How to distinguish male and female yew trees?

Question 1: Are there male and female yews? 30 points Yew is a shallow-rooted plant with an unobvious main root and well-developed lateral roots. It is recognized as an endangered natural rare anti-cancer plant in the world.

The male and female yews can be distinguished during the flowering period: the male ones are slightly thinner and cannot bloom and bear fruit, while the female ones are not only lush, but also produce bright red fruits every autumn.

Question 2: How to distinguish male and female yew trees. It’s best to explain it with pictures. It’s easy to tell when it’s in bloom, but it’s basically impossible to tell with the naked eye without seeing the flowers. The male flowers are yellow and spherical, spreading out, with many anthers; the female flowers are orange-red and always in the shape of small balls.

Question 3: How to distinguish male and female yews? The male and female yews are mainly distinguished by their leaves. Female plants have straight and dense leaves, and their growth rate is slower than that of female plants. Then here comes the problem! What is dense, what is sparse, and what speed is slow! There is no intuitive explanation! This answer actually doesn’t solve the problem! Right! Today I will put this issue to the point without any ambiguity! There are pictures and the truth!

How to identify male and female yew plants? The most practical way is to look at the flowers. The first thing to state is that yews will bloom regardless of whether they are male or female! The male flowers of Taxus are spherical, with short stalks, light brown to yellow, 5 to 6 mm long, about 3 mm in diameter, densely grown in the leaf axils on both sides of the branches, with 6 to 14 stamens, shield-shaped, and each branch has 5 (4 to 9) stamens. An anther. The female flowers are nearly spherical, sessile, 5 to 6 mm in diameter, disc-shaped on the pericarpate, and have sparse solitary branchlets in the leaf axils on the back. Okay, without further ado, here’s the picture!

The difference between the two types of flowers is particularly emphasized here: the male flowers have short stalks, and the female flowers are sessile; the male flowers are densely borne in the leaf axils on both sides of the branch (to put it bluntly, they are in clusters); the female flowers are sparse and solitary in the leaf axils on the back of the branch (female flowers are Definitely not one flower next to the other).

The flowers of male yew grow on the underside of the leaves, while the flowers of female yew grow on the top of the flower axis, and there is an obvious seed coat under the flower disk. Secondly, you can also observe whether the yew flowers have stamens. As long as the function is pollination, the stamens are 6 to 14, shield-shaped, and each stamen has 5 (4 to 9) anthers. If it is a Mandian yew, you can also distinguish male and female yews by the way their leaves grow. If the leaves are ringed, the plant is a female Mandean yew, and if the leaves are double-layered, the plant is a male Mandean yew.

Taxus is dioecious. The male cones are solitary in the leaf axils, and the ovules of the female cones are solitary at the top of the short lateral axes on the upper part of the flower axis, with a disc-shaped aril at the base. The seeds are flat and oval, with 2 ribs, oval in shape, cup-shaped aril, and red. The female yew trees bear fruits, which are red and look better. However, it takes a long time for the yew trees to bear fruit, which can take as little as 10 years, and certain pollination conditions are required!

Question 4: How to distinguish male and female yews? For Mandya yew, you need to rely on experience to distinguish seedlings within 2 years. For seedlings more than 2 years old, the simplest method is to have flower buds starting in July and next year 3 The ones that bloom in the moon must be male. The flower buds of male trees are larger and more obvious, and the flower buds are round. The flower buds of the mother tree are very small, and there are small water droplets on them when they bloom in March. Compared with the male tree, the leaves of the female tree are shorter, thicker and darker in color. The growth rate is also much slower than that of the male. There is also a method to identify the male and female on the leaves, but not everyone can learn it at once. You need to look more. No one can tell the difference between male and female Southern yew trees before they bloom and bear fruit. Generally, it takes at least 7 years to bear fruit.

Question 5: How to identify the male and female yew trees? I spent 1100 to buy a fruit-bearing yew bonsai. It is true that there is one female and one male. The male is higher and the female is lower. I will switch to another computer to see the picture above gt; gt;

Question 6: How to distinguish male and female yew. The male cones are solitary in the leaf axils, and the ovules of female cones are solitary at the top of the lateral short axis in the upper part of the flower axis, with a disc-shaped aril at the base. The male cone has 9 to 14 stamens, and the female cone has one ovule, which is oval, light red, and straight. The male to female ratio of wild yew is generally 1:9, while the male to female ratio of yew in artificial plantations can reach about 3:7. The sex of the seedlings cannot be distinguished.

The results over several years vary depending on species, management measures, and natural conditions.

Assuming that yours is a yew, it is confirmed to be correct. Under normal natural conditions, it will bear fruit in the fifth year. Anyway, the results within five to seven years are considered normal. Of course, you can also manage it to make it bear fruit in the third year

Its material is excellent, with straight texture, dense structure, elasticity, high mechanical strength, glossy, fragrant, resistant to decay, not easy to crack and warp, does not contain rosin, the sapwood is narrow and yellowish white, and the heartwood is purple auburn (yew is therefore named).

Question 10: How to distinguish male and female yew trees? They can be separated when they bloom. The flowers on the male tree are as big as half a small fingernail.
