How to distinguish a male and female ginkgo tree? The difference between male and female ginkgo tree

As we all know, people are divided into male and female, and animals are divided into male and female, which is the law of survival in nature, but some fruit trees in fruit tree seedlings are also divided into "male and female", that is, male and female plants, and ginkgo biloba trees are this kind of seedlings.

Morphological and structural differencesThe seedlings of female Ginkgo biloba showed the characteristics of short stem, early germination and late defoliation. The outer edge of the leaves of adult trees is shallow, the branches are open and layered, the proportion of long branches is small, and the crown is sparse. The opposite is true for male plants. However, these nuances are also affected by a variety of factors, and sometimes it becomes difficult to distinguish, so they can be used as preliminary judgments because of the simplicity of the method.

This is a male tree leaf, and it is obvious that the middle carved line is deeper.

Since ginkgo trees are divided into "male and female", how should we judge the "cemetery" of ginkgo trees in normal life? I'll teach you a few tricks today!

1) Distinguish from the body of the ginkgo tree:

Ginkgo biloba males are usually tall. The female ginkgo tree is slightly shorter.

2) From the posture of the tree: Usually the male ginkgo biloba is upright, and the tip of the branch is small, but the base angle of the branch is large. The female ginkgo biloba tree is open, and the tip of the branch is large, but the basal angle is small, especially after fruiting, the waist angle becomes larger due to the effect of fruit pressing the branch.

This is the mother tree leaf, with a shallow middle notch.

3) Judging from the number of ginkgo branches: the branches of the male plant are sparse and the layering is obvious. The female plant has more branches, the branches are densely crowded, and the layering is not as obvious as that of the male plant.

4) Distinguish from the cracks and colors of the bark: the cracks of the male plant are deep, the color is dark, and the dry bark is rough. The female plant has light cracks, light color, and is grayish-white.

Staminate flower. 5) From the length of the flower branches: the length of the flower branches of the male plant, generally 1 4 cm. Female plants have short flower branches, generally 1 2 cm.

6) From the leaves: The leaves of the male plant are dark in color and fall late in the leaves. The female plant is light in color, and the leaves turn yellow after autumn and fall early.

7) From the seeds: the pits are pointed at the head, and there are three-edged seeds to raise male plants. The kernel is round, and there are two-edged seeds to raise female plants.

Female flower. 8) From the flower buds and inflorescences, the male flower buds are large and full, and the top is flat. The flower buds of the female plant are thin and pointed. The male inflorescence is a soft inflorescence and resembles a mulberry flower. The female inflorescence grows at the tip of the peduncle, splits into two forks, and resembles a matchstem.

Ginkgo biloba male and female are mainly based on experience, and need to be seen and compared.

1) The male tree is upright and has branches stretched out. The female tree is open and flattened.

2) The branches of the male plant are sparse and layered. The female plant has more branches, the branches are densely crowded, and the layering is not as obvious as that of the male plant.

3) The bark of the male plant is deeply cracked, dark in color, and the dry bark is rough. The female plant has light cracks, light color, and is grayish-white.

4) Male plants have long flower branches, usually 1 4 cm. Female plants have short flower branches, generally 1 2 cm 5) Only female plants can bear fruit.

Look at the shape of the tree, the trunk is straight and does not fork, and the length is the same as that of bamboo, which is male. The main trunk will fork, and the one that grows around the crown will be female, and the female will bear fruit, but the male will not.

It's very simple, look at the leaves, it's easy to tell! The leaves of the male tree are forked a little.

Is it that complicated? The ginkgo fruit is the mother, and the book bag is dropped one by one.

Is there any way for a male tree to make it bear fruit?

Sometimes I don't like ginkgo because so.

The differences between male and female ginkgo trees are as follows:

1. If large seedlings are used in construction, and the seedlings are not in the flowering period, then we can distinguish between male and female according to the comparison of branches and leaves

1. The leaves of the male plant are larger than those of the female plant, and the lack of carves is deep. There is a lipid gap around the vascular bundles of the leaves of the female plant, while the male plant does not.

2. The male plant has short branches, only about l zcm. The short branches of female plants can extend to more than 10 cm due to the continuous seeding for many years, so the short branches appear to be longer.

Second, if the seedlings are in the flowering stage, then we can combine the flower buds and inflorescences according to the above two points to distinguish the male and female more accurately

1. The flower buds of the male plant are large and full, and the top is flat. The flower buds of the female plant are thin and pointed.

2. The male inflorescence is a soft inflorescence, and the appearance is like a mulberry. The female inflorescence grows at the tip of the peduncle, splits into two forks, and resembles a matchstem.

3. If small seedlings are used in construction, they must be carefully separated, and if only a few plants are used, they must be clearly distinguished. In addition, it should be noted that the general nursery chooses to compare with trees of the same age

1. The crowning time of male plants is late, and the defoliation is also late, and the branch level is clear; Early spring germination is relatively early. The female plant has an earlier crowning time; Autumn leaves also fall early; There are many branches, and the arrangement is very scattered.

2. The most obvious and useful difference in practice: the angle between the main school and the main trunk of the male plant is very small, mostly within 30 degrees Celsius, and some are almost parallel to the main growth. The straight branches look thicker and better than the female.

The female plant has a large angle. It can reach more than 50 degrees Celsius, and some seem to grow perpendicular to the main trunk, and expand in all directions.

As the temperature in our country drops, it is time for some plants to begin to disguise, and in autumn it is a season of color change, and in autumn there are ginkgo biloba on both sides of the road.

The falling leaves are really beautiful. While enjoying the beautiful scenery, no one will notice that some ginkgo trees have a lot of fruits, but some are lightly armed and straight to the sky, in fact, in our country ginkgo biloba is divided into male and female trees, and the male trees of ginkgo only bloom and do not bear fruit. Many people do not know much about the division of ginkgo trees into male and female, and we see that female trees are relatively short, and male trees are taller.

And if you look closely, the canopy of the two trees is also different, we see that the angle between the branches of the male ginkgo tree is smaller, the branches look relatively long, and the branches are luxuriant, and the whole crown looks like a tower, and the top and bottom are very beautiful. The branches of the female ginkgo trees we see are more scattered, the trunk is the angle of the branches looks relatively large, and the whole crown looks round like a ball from a distance. The depression on the edge of the leaves of the female tree is relatively shallow, and the leaves will turn yellow and fall early after the autumn of each year, and the leaves of the male tree are larger than the female trees, and the depressions on the edge of the leaves are deeper.

The above is an introduction to how to distinguish between male and female ginkgo.

Yes.

Ginkgo biloba (scientific name: ginkgobilobal.).) is a deciduous tree of the family Ginkgo and Ginkgo biloba.

Ginkgo biloba appeared hundreds of millions of years ago, is the oldest relict plant of gymnosperms left after the Quaternary glacial movement, the surviving ginkgo biloba is scarce and scattered, hundreds of years old trees are rare, and all other plants of the same class have been extinct, so ginkgo biloba has the reputation of living fossils. There are 26 varieties and varieties: yellow-leaved ginkgo, tower-shaped ginkgo, split ginkgo, weeping ginkgo, spotted leaf ginkgo and so on.

<> female (female) ginkgo tree: the plant planted by the 2-edged ginkgo fruit is a female plant, the angle between the female plant and the main trunk is about 50°, the crown is large, the female plant has a notch in the middle of the leaves, and the flowers have long stems.

Male (male) ginkgo tree: The plant planted with 3-edged ginkgo is a male plant, the angle between the male plant and the trunk is about 30°, the male plant leaves are more missing, and the flowers are inflorescence-like.

1. Fruits. Some places sell fried ginkgo fruit, in fact, it is ginkgo biloba, people generally see the ginkgo fruit is 2 edges, and there are a few of them are 3 edges, that is, the head of the ginkgo seed is round and has 3 edges, these are also one of the characteristics of distinguishing male and female, among which the ginkgo biloba planted by the ginkgo fruit with 2 edges is a female plant, and the plant planted with 3 edges of ginkgo fruit is a male plant, and at the same time, from the ratio distribution, the mother fruit of the ginkgo fruit accounts for about 95% of the proportion.

2. Canopy morphology.

Generally speaking, the angle between the female plant and the trunk is about 50°, and the angle between the male plant and the trunk is about 30°, which also makes the crown of the female plant larger, and the crown of the male plant is spire-shaped.

3. Leaf type. Generally from the ginkgo leaves picked down to distinguish, it is easy to judge the male and female ginkgo biloba, the more obvious difference is that the male leaves are more missing, and the female is only one missing in the middle, if you subdivide it, you can see that the male in the middle of the missing is very deep, and the female is relatively shallow.

Fourth, flowers. The flowers of the male ginkgo tree are inflorescence-like, drooping, the stamens are loosely arranged, with short peduncles, the apex is flat, and the flowers are shaped like caterpillars; The flowers of the female ginkgo tree have long stems, and the end of the stem is often divided into 2 forks, similar to a "ya" structure, and the two forks at the top are each 1 ovule (the predecessor of the seed), and a small part is 3-5 forks or no forks, and generally only 1 fork end of the ovule can develop into seeds.

<> Ginkgo biloba trees are male and female (male and female). Ginkgo biloba is a dioecious plant, male beads can not bear fruit, female beads can bear fruit, but the fruiting period will be very late, generally takes 20 years and more, but you can use the method of grafting male and female plants with each other, so that male beads can bear fruit, female beads can speed up the fruiting time, generally 2-3 years can flower and bear fruit.
