03:23Spanning different climate zones and diverse mountain and landforms
03:27Arriving in the Fruit Paradise of China
03:33This is one of the world's most important centers of origin for fruit trees.
03:37There are approximately 700 fruit tree species, accounting for more than half of the world's total.
03:47Citrus fruits are a special category among them.
03:52The citrus family has many members, including many important species.
03:55Most species originated in China
03:58As the world's largest fruit category, the taro family is a global agricultural trade...
04:03Yi Zhong occupies a very important position
04:05Members of the Citrus Family; Members of the Osmanthus Family; The Huge Size of the Osmanthus Family
04:20Beyond imagination
04:22These fruits of different sizes and shapes
04:25They are all children of the citrus family.
04:29Why does this family have so many children?
04:37These are the three elders of the citrus family.
04:39That is, their ancestors
04:44The first elder was Xiangyuan
04:46Thick skin and little meat
04:47sour and astringent taste
04:50The second one is called Orange.
04:52Loose peel
04:54Juicy and plump flesh
05:00The third veteran is Yuzu.
05:02Large
05:03The flesh is egg-yellow
05:16Fruits in this family
05:18Any two can hybridize to produce a new species.
05:25In nature
05:26Not all plants possess this ability.
05:30The citrus family, however, is not restricted.
05:32The variety is therefore increasing.
05:37Early
05:38Oranges are produced by crossbreeding tangerines and grapefruits.
05:41It also crossbred with another veteran, Xiangyuan, to produce Lemon and Crude Lemon.
05:47Later, oranges were crossbred with their ancestor, Xiangyuan, to produce lemons.
05:51Grape lemon was created by crossbreeding with the ancestral pomelo.
05:56This epic ethical drama that keeps unfolding in nature
05:59The citrus family is growing larger and larger.
06:10In search of deeper secrets of reproduction
06:13People are exploring at the cellular level of citrus fruits.
06:18Green and white solutions in the test tube
06:21They came from two different varieties of citrus.
06:29Under an optical microscope
06:31After magnifying them 40 times, you can see
06:34Two types of cells with their cell walls removed
06:36They gradually merged into one in just 60 seconds.
06:48Open life attributes
06:50It makes it easy for members of the citrus family to occur.
06:53Such a wonderful reaction
06:55The fused cells were then cultured.
06:57Perhaps this will give birth to a new species that will have a global impact.
07:03Human creativity
07:04Shortened the cycle of new members appearing in the citrus family
07:08But in nature
07:09This often requires waiting for a chance encounter.
07:201820
07:21One gene mutation
07:23The citrus family has gained a special new member.
07:37After consuming a large amount of nutrients
07:39The tree is in full bloom.
07:42White flowers hung all over the branches
07:46Most plants can transmit energy through their flowers.
07:48To produce seeds and reproduce offspring
07:51However, this tree is quite special.
07:53Its flowers were filled with extraordinary anticipation.
07:59The fruit that grows contains only pulp.
08:02No seeds
08:03It is Qicheng
08:10Unable to reproduce through seeds
08:12Qi Cheng became the only descendant in the citrus family.
08:26Long before Qi Cheng appeared
08:28Humanity is inspired by nature
08:30Invented a surgical procedure
08:57Two different trees connected together
09:00Natural healing and regrowth
09:02Capture and nurture new life
09:04This is the fake street.
09:211870
09:22People saved Qicheng with fake streets.
09:24It can reproduce even without seeds.
09:34Through fake streets
09:35People's appetites were satisfied.
09:39And Qi Cheng's fate was completely changed.
09:45Using human desires
09:46Qicheng was able to thrive and multiply on Earth.
10:15Royal Tree
10:18Julai Fuxi
10:21Lifespan does not change
10:23Saint South West
10:26Chamomile is a plant that was once a part of the spiritual life of the Chinese people.
10:30Fruit played an important role
10:34More than two thousand years ago
10:36Qu Yuan wrote the Ode to the Chrysanthemum
10:38Praising the chrysanthemum tree, the most beautiful tree in the world.
10:42Praise its independent, unyielding, and noble character.
10:48At that time
10:49It was once a spiritual totem for the Chinese people.
11:03Spreading westward
11:05In Israel, the garden of perilla is regarded by the Jews as a symbol of God.
11:101471 AD
11:11Chamomile-type fruit trees were introduced to Portugal
11:14Planting began along the Mediterranean coast
11:18King Louis XIV of France was obsessed with the taste of oranges.
11:21It was planted all over the Palace of Versailles
11:25Age of Exploration
11:26Scurvy killed hundreds of thousands of sailors
11:30But Captain Cook's three voyages
11:32However, not a single crew member died from the disease.
11:36Captain Cook's Savior
11:38Also from the citrus family
11:40Qingning
11:42Later research revealed that...
11:44It was the vitamin C in Qingning that made the difference.
11:48It is precisely because of Qingning
11:49People discovered vitamin C
11:51This also marked a step towards the birth of modern nutrition science.
12:01The citrus family of fruits with different shapes and colors
12:04With their ever-changing flavors
12:07Captured humans
12:08It nourished humankind
12:09It also cultivates people's imagination of taste.
12:15Also because of human beings
12:17The citrus family is growing stronger.
12:19It has become the world's best-selling fruit category.
12:41The Yangtze River Basin is one of the richest regions in China in terms of plant resources.
12:47Deep in the mountains of this watershed
12:49There is a place called Da Lao Ling
13:01The wild plant resources here are ancient and unique.
13:04It was once a paradise for botanists to discover new species.
13:32Botanist Huang Hongwen is currently searching for a type of wild fruit.
13:46This wild fruit is hidden deep in the jungle at an altitude of 1,700 meters.
14:04More than a hundred years ago
14:05Commissioned by a British nursery
14:07Botanist Wilson also searched for this fruit.
14:12Huang Hongwen is retracing Wilson's route today.
14:22Wilson visited China four times in his lifetime.
14:26He spent nearly twelve years on it.
14:28More than 65,000 plant specimens were collected in China.
14:32Many new species were discovered.
14:34And successfully transplanted more than 1,500 kinds of native Chinese plants.
14:39Economic plants introduced to Europe and America
15:10Hua Hongwen is looking for everything
15:12This jungle is teeming with poisonous insects, snakes, and wild animals.
15:19Wilson risked his life to enter this unknown area.
15:23Just to discover plants and collect and introduce them.
15:38In the course of human civilization
15:40The introduction and domestication of important plants often drive economic and social development.
15:44Even changed human history
15:51The greatest contribution a botanist can make
15:53Nothing beats adding a useful cultivated plant.
16:01Wilson may have been trying to fulfill this wish.
16:04Only then can it travel upstream along the Three Gorges Gorge time and time again.
16:11Every step he took was exploratory at the time.
16:19I've definitely been to this place before.
16:20The stream back then was far from what it is now after the Three Gorges Dam was built.
16:25Water level rise
16:26The water is so wide, so deep, and so calm.
16:28You can bump into a stone anywhere.
16:30This kind of shipwreck and man-destroying situation is happening frequently.
16:34As long as it is transported by boat
16:36Sailing is also a gamble.
16:45A difficult gamble
16:47A wild fruit came into Wilson's view.
16:52In the south it is called starfruit
16:55In the north, it's called dog date.
17:02Today it is well-known to people.
17:04kiwi
17:11Slender vines
17:13It cannot grow upright
17:15One must rely on something else to climb upwards
17:22For them
17:24Surviving deep in the forest is no easy task.
17:30Kiwifruit is a typical vine plant.
17:34After taking root
17:35It then issues commands to all the new vines.
17:38Climb as high as possible
18:08Because they can only climb on tall plants
18:10Only then can it seize the passage closer to the sky.
18:14Rare resources bathed in the dense forest
18:17Sunlight
18:25Leaves grew on the vines
18:27Food is produced after absorbing sunlight.
18:29Kiwifruit can survive
18:35In order to find taller trees
18:38Climb higher
18:39Kiwifruit can sometimes even grow in an area of ten acres.
18:42An area equivalent to the size of a football field
18:45keep searching
18:52This way, every penny is precious.
18:53A single vine can often climb across an entire forest.
19:09Survival is already difficult
19:11And the desire to reproduce through flowering and fruiting
19:14Other opportunities are needed
19:26Kiwifruit meticulously planned an encounter.
19:29It is waiting for a helper to arrive.
19:34Starting from dawn
19:35The kiwi opens its petals.
19:52It will take several hours of effort.
19:54Only then can its petals fully open.
20:08When the sun dries the flower stamens
20:11Bees appeared
20:26Kiwifruit is a monoecious plant.
20:30Its male plants only have stamens.
20:32Able to produce pollen
20:36Although female plants have both pistils and stamens
20:39But the stamens are just for show.
20:41The pollen produced is infertile.
20:51Therefore, only when the bee pollinates the stamens on the male flower...
20:55Spread to the stigma of the pistil
20:57Only then can kiwifruit possibly bear fruit.
21:15More than a hundred years ago
21:16Wilson carried kiwifruit out of the mountains.
21:20When arriving at Yichang Port
21:21The secret to kiwi fruit reproduction
21:24Still know nothing
21:30Although it sent kiwi seeds to Britain and the United States
21:34But kiwifruit grown from these seeds
21:37It just so happens that they are all male pigs.
21:39Unable to bear fruit
21:43that's all
21:43Kiwifruit embarks on its first global expedition
21:47It ended in failure.
21:59Yichang Port
22:01Kiwifruit is destined for a miraculous life adventure.
22:05At that time, through Wilson
22:07Kiwifruit and Isabel, a female teacher from New Zealand
22:11Encounter
22:14This place, this house, is the Scottish Evangelical Fellowship.
22:18Isabel lives in this location
22:21After Wilson returned
22:22Just take the kiwi fruit
22:24It was inhabited by Europeans
22:27It's a miscarriage.
22:28Give them food
22:29Share his collection results
22:34Isabel not only tasted this delicious fruit
22:38He also brought his seeds to New Zealand.
22:42This wild fruit was originally hidden deep in the mountains
22:45Another opportunity to change one's destiny has arrived.
22:51Kiwifruit crossed the equator to reach the unfamiliar Southern Hemisphere.
22:55But the failures they had previously suffered on the European and American continents
22:58Will it happen to him again?
23:041904
23:05Isabel handed over a handful of seeds to local fruit farmers to plant.
23:09Kiwi fruit was adopted
23:12Fortunately
23:13New Zealand for kiwifruit
23:15It is a perfect cradle
23:18There are no consecutive low temperatures here in winter.
23:20There is no frost in spring.
23:22More importantly
23:24The soil here is loose and well-drained.
23:26It perfectly meets his survival needs.
23:431910
23:44This plant in the orchard is called Chinese goose plum.
23:48Finally, there is a record of fruition.
23:52at this time
23:52He has been in New Zealand for six years.
23:56first
23:57Kiwifruit flowers and bears fruit outside of China
24:01He finally ushered in a new life in the Southern Hemisphere.
24:05And all of this stemmed from the seed that was cultivated.
24:08A bear-pig
24:09Two Magnetic Pigs
24:10Luck has been on New Zealand's side.
24:23At the beginning
24:24Kiwifruit is only spreading among plant enthusiasts.
24:27However, through continuous domestication and improvement
24:29It has a multi-layered sweet and sour taste.
24:36When humans choose fruit
24:37Taste is an important criterion for making a judgment.
24:41This preference is not only controlled by genes
24:44It is also influenced by the environment and life experience.
24:47People from the same region often have similar tastes.
24:54Kiwifruit has such a rich variety of flavors
24:57How can we choose the right type for different groups of people?
25:01A test has begun
25:10Scientists recruited a group of people who had just arrived in the area
25:12Consumers whose tastes haven't changed
25:15They carefully selected fruit samples for testing.
25:20In order to avoid people's prejudice
25:21They used irregular three-digit numbers to label kiwifruit.
25:25And the distribution was disrupted.
25:27To prevent people from guessing Yu Lie based on the order
25:32Then use color-changing lights to subtract the effect of color difference.
25:37All experimental samples were provided in the same manner.
25:41There is only one purpose to do this.
25:43That is to get people away from all distractions.
25:45Judging solely based on the taste of the kiwi fruit itself
25:59Kiwifruit satisfies New Zealanders' pursuit of the ultimate flavor.
26:03However, its early fruits are very soft.
26:06It is easily perishable and cannot be transported over long distances.
26:11Kiwifruit needs to be sourced from New Zealand, located in the Southern Hemisphere.
26:14This problem must be solved before we can reach other continents.
26:18Will it have another extraordinary encounter?
26:28This is Ayiri, a local Chartreux.
26:33More than a hundred years ago
26:35This is the Sharda of Sharda of Sharda.
26:38We can see the Shattal's Shattal.
26:41This is the new journey.
26:42In the Saudi Arabian Saudi Arabian Saudi Arabian Saudi Arabian
26:46These are all new houses.
26:48But some of them should be those antem will
26:5250-100 billion cloud
26:55Hayward White sowed seeds in the nursery.
26:59Through its continuous development
27:011928
27:02Forty kiwifruit plants have grown here.
27:05One of the plants had large fruits.
27:07Good taste
27:08Most importantly, it is durable and can be stored for a long time.
27:11This variety was later called
27:13Hayward
27:27Chance opportunities created jointly by nature and humankind
27:30This changed the fate of kiwifruit once again.
27:35The potential of the seeds is fully developed.
27:37Kiwifruit has since embarked on a long journey.
27:40The possibility of going global
27:44It then ignited the passion of New Zealanders.
27:47It began to be planted on a large scale
27:55New Zealand's kiwifruit harvest season begins in April.
28:00In order to unify management
28:01The fruit farmers had already formed an organization.
28:04From variety selection and orchard planning to production and transportation
28:08They all have a set of scientific procedures
28:33A thorough examination was conducted on weight, hardness, color, dry matter, and sweetness.
28:38back
28:38The kiwifruit can finally be picked!
29:01New Zealand accounts for one-third of the world's kiwifruit production.
29:06And the hometown of Chinese kiwifruit
29:09It has become its largest sales market.
29:27In 1904, kiwifruit was still a wild fruit.
29:341910
29:35It was reborn in New Zealand
30:05And it has a new name
30:07It is exported to 59 countries and regions around the world.
30:10It became the country of New Zealand
30:13Accompanying the discovery and domestication of a species
30:16A fruit industry system was born.
30:19In a sense
30:21Kiwifruit even changed the fate of a country.
30:33apple
30:34apple
30:34An ordinary yet extraordinary fruit
30:38It is hailed as the king of fruits in many regions.
30:42It has more than 7,500 cultivars.
30:48The apples that people eat today are modern apples.
30:52It has been less than 150 years since it landed in China.
31:06Ancient times
31:07If people find a sweet apple
31:10I will eat it immediately
31:13Because sweet foods are high in calories
31:14It can provide more energy to sustain life.
31:27Sweetness seems to mean being able to fill your stomach.
31:31In the long process of evolution
31:33The pursuit of sweetness has gradually been etched into the human gene pool.
31:37Until now
31:38Sweetness can still evoke pleasure in people.
31:46Big and red
31:47Sweet and crisp
31:49The taste of each fruit is almost exactly the same.
31:53Red Fuji born in Japan
31:54This satisfies human needs to the greatest extent possible.
31:57The pursuit of sweetness
32:00In China, the world's largest apple-producing country
32:02Red Fuji became the most popular variety.
32:0670% of apple orchards
32:08They planted all of it.
32:11But humanity's ultimate pursuit of flavor
32:13However, this has led to a decrease in the variety of apples.
32:19For all species
32:21A single entity often implies risk.
32:25So
32:25What are the ways to mitigate this risk?
32:43The heartland of Eurasia
32:45Deep in the Tianshan Mountains
32:47Large areas of wild fruit forests are distributed.
32:50This is an important genetic treasure trove for apples.
32:54Millions of years
32:55Wild apple trees thrived on this land.
33:00During the last ice age
33:02This was their last refuge.
33:06In the coconut grove
33:08Apple King stands tall at the highest point
33:11He is over six hundred years old
33:13Surviving through the Ming and Qing dynasties of China to this day
33:18It is in this wild fruit forest
33:20The oldest fruit tree
33:32For many years
33:33Numerous animals and fungi have made their home on the King Apple.
33:37Many movements and grooves were left behind.
33:40But the Apple King and they lived in peace.
33:44Because during the long process of evolution
33:46They have learned to live in harmony.
33:53During a bumper harvest
33:54This apple king can still wrap around more than 600 pounds.
34:06No two leaves in the world are the same.
34:09This statement is more accurate when applied to Apple.
34:13Every seed of an apple
34:14All contain a completely new set
34:16Completely different genetic structures
34:18It can grow different kinds of fruit trees.
34:22In this kingdom beneath the feet of the Apple King
34:24Apple trees come in all shapes and sizes
34:26Each one is unique.
34:29This diversity is precisely
34:31The vitality of wild apples
34:42The secrets to the life of apples are hidden in the wild fruit forest.
34:47However at this moment
34:48These wild apples are facing...
34:50An unprecedented test
35:18The killer is hiding in
35:19Unseen places
35:22These larvae are only 15 to 22 millimeters in size.
35:34They hide inside the apple branches.
35:37With the weapon of hard evil
35:39Continuously gnawing on tree branches
35:41Damaging the fruit tree's ability to transport nutrients
35:45Apple trees that do not receive enough nutrients
35:48He withered and died.
35:51Look, these are the paths it walked after it finished eating.
35:53Look
35:55It's all empty inside.
35:56What do we Kazakhs say?
36:00This is ironwood.
36:02The hardest is fruitwood.
36:03It can drill.
36:04Look
36:05You said the skin can be removed.
36:06It burrows into the heart of the tree.
36:08Look
36:10Inside the tree heart
36:11Just like the human heart
36:191993
36:21At the foot of Tianshan Mountain
36:23People grafted the things brought from the mainland
36:25Unsimplified apple twigs
36:28These creatures are called jewel beetles.
36:30And followed
36:33Its sudden invasion
36:34It broke the whole wild apple grove
36:36The original ecological balance
36:38The wild apple tree was caught off guard
36:40No defense mechanism has been established yet
36:44This insect has reproduced rapidly.
36:46A population was formed
36:52Apple King stood on the high place
36:55They escaped the harassment of the small jewel beetle.
36:59But at the foot of the mountain
37:00Its companions were not so lucky.
37:03The vast majority of wild apple trees
37:05Drying out or dying
37:08The Apple empire is collapsing.
37:17Apple genetic diversity
37:18This gift from nature
37:20It is precarious because of people's negligence.
37:36Fortunately, the Chinese scientific community
37:38The seriousness of this problem has been recognized.
37:41They are in a competition with the jewel beetle.
37:44Find a way to solve this problem
37:56Botanists almost every year
37:58Everyone wants to come to this wild fruit forest to collect samples.
38:00Investigating the survival status of wild apples
38:13They utilized the genes of wild apples from Xinjiang.
38:16They have cultivated a variety of apples, including those with entirely red flesh.
38:19Help the Apple Kingdom rebuild its home
38:29Now, even with human assistance...
38:31But to survive on this planet
38:34Apple has to become stronger itself.
38:41Because of this battle for survival
38:43Never-ending
38:49And the wild apple grove is a testament to human thought.
38:52How to get along with plants - an old, familiar place
38:59It is also a new starting point for harmonious coexistence between humans and nature.
39:29This is the highest place in the world.
39:32Qinghai-Tibet Plateau
39:36A fruit that is very familiar to Chinese people
39:39His hometown is here.
39:49Yarlung Tsangpo River
39:50For this cold place
39:52A water vapor channel was left behind.
39:54It also left a chance for life.
39:58Hundreds of millions of years ago
39:59When the ancient glacier retreated from here
40:02It left behind a series of weapon-themed hills
40:07In this environment
40:08This is the only plant that appears in large patches.
40:13It is the ancestor of the peach.
40:15Its name is Guanghe Peach
40:21Backed by towering mountains
40:23A clear river flows beneath my feet.
40:26The Peach of Light River with extremely strong vitality
40:28Feeling exhilaration and pride in this home
40:31The robustness and grandeur of growth
40:44To adapt to this high altitude
40:46Low-temperature and low-oxygen living environment
40:48Guanghe Peach tries to consume as much energy as possible.
40:51Reduce to the lowest level
40:53Maintaining this low-consumption state
40:55Only then can it store energy.
40:57Bloom early
41:11The pollen morphology of Prunus guanghei is simple.
