What are the differences between flower buds and leaf buds? How can you tell the difference?

Accurately identify apple trees.

The flower buds and leaf buds are extremely important to guide the pruning of fruit trees, reasonably adjust the load, overcome the "big and small years", and ensure the high yield and quality of fruit trees. When spring comes, the sap slowly begins to flow, which is the key time for spring pruning.

1. Leaf buds1. Armpit leaf buds:The body is flattened and short, mostly triangular.

It is attached to the branches, the tips of the buds are small and not skewed, and the scales are dark and hairy. Its internal characteristics are similar to those of the parietal leaf bud.

2. Parietal leaf buds:The buds are thin and erect, thin and shriveled, with a thick neck. The scales are hairy and flaccid, the brown edge is broad, and the middle scale is not large or prominent.

The protrusions of defoliation marks are not obvious, the scales are few and loose, the ridges start obviously, the hands are soft and soft, the hairs are many and long, the buds are dark and dull, the scales are peeled off, and there are 3 10 needle-like green tender tips in the buds, which is the prototype of next year's leaves.

2. Flower buds1. Top flower buds:The neck is thin, the bud body is full and full, the shape has obvious ridges, the tip of the bud is obtuse and skewed to the side, the number of scales is large, the hugging is tight, and there is a large and prominent scale in the middle to buckle the top of the bud body. The scales of high-quality flower buds are sparse and shiny, and the brown parts of the margins are narrow and indistinct.

Most varieties have three prisms on the bud body, with a large scale protrusion in the middle, the base of the bud is thinner, the upper part is tilted to the side, and the lower part of the defoliation mark protrusion is obvious. Peel off the scales, and there is a clump (2 7) of small hairy green particles in the bud, which is the spring flower bud.

Everyone should pay attention to the fact that the top flower buds are generally full, so the result is ***, so try to keep it when the amount of flowers is insufficient!

2. Armpit flower buds:It is usually found in the autumn shoots of well-developed branches. The external morphological characteristics are:

The bud body is thick and oblong-oval, obviously larger than the lateral leaf buds, most of the bud tips are skewed, the buds are slightly open from the outward, not close to the branches, and the scales are bright and hairy. Its internal characteristics are similar to those of the terminal flower buds, except that the young round balls are smaller and slightly flattened, and the number of small round balls is smaller. Many varieties such as Golden Crown and Fuji (Qiaohua) can form axillary flower buds, especially for large year trees.

Generally speaking, the flower buds of strong trees are full and full, while the flower buds of weak trees are relatively thin; The flower buds of different branches are different from one part to another, and the flower buds on the inner chamber, the bottom and the weakened branches are thin, while the flower buds on the upper and robust fruit branches are hypertrophied. Therefore, when pruning in spring, it is enough to distinguish between flower buds and leaf buds.

The flower buds are fuller, and the leaf buds are thinner. The flower buds of strong trees are full and full, while the flower buds of weak trees are relatively thin. The flower buds of different branches are different from one part to another, and the flower buds on the inner chamber, the bottom and the weakened branches are thin, while the flower buds on the upper and robust fruit branches are hypertrophied.

Generally speaking, the flower bud body is hypertrophied and full, the tip is round and blunt, the scales are many and bright, and the hugging is tight, and it feels hard when pinched by hand, with fewer hairs, darker color, prominent prismatic body, and the leaf marks are prominent and pimple-like, and after peeling off the scales, there is a small green round ball in the middle. The leaf buds have smaller buds, fewer scales, and looser holdings, and after the scales are peeled off, there are several needle-like green tines in the middle.

Since flower buds are formed by the differentiation of leaf buds, it is difficult to distinguish between the initial stage of flower buds and leaf buds. In the past, it was thought that the base of the young shoots was more enlarged than flower buds, but now it seems to be unreliable. According to the anatomical observation of young shoots, the apical part of the axillary bud primitive body of each young bud will always develop into a leaf bud in the future, and only the axillary bud primitive body on the scales may develop into a flower bud in the future, so the young bud is a mixed bud.

Flower bud differentiation is basically over from mid-June to late August. The flower bud has a long stalk, the growth cone is relatively rounded, and the leaf primordium is underdeveloped, located at the base of the young bud. The leaf buds are not stalked, the growth cone is slightly pointed, and there are 3 7 original leaflets, located at the top of the young buds.

The apical buds are generally 1 3, more than 5, the middle one is a leaf bud, and the rest are flower buds. If there is only 1, it is a leaf bud. The leaf buds are thin and long, and the flower buds are round and fat.

During the development of flower buds, the leaf buds are latent, and sometimes the leaf buds shrink and fall off due to the strong development of flower buds. If the nutrients are abundant, the leaf buds and flower buds develop at the same time; If the nutrients are insufficient, the leaf buds are inhibited by the flower buds. Therefore, when the flower buds are formed, strengthening the fertilization management of Camellia sinensis can promote the formation of flower buds.

How to distinguish flower buds and leaf buds, look at these 2 orchids, the seedling type is rare, the orchid leaves droop and elegant, the flower buds and leaf buds should be distinguished, Suizhou fragrant orchid.

Leaf buds are primitive bodies of undeveloped shoots. The structure of the longitudinal cut leaf bud is as follows:

Bud axis: **axis, on which all parts of the bud are born, is an undeveloped stem.

Growth cone: Meristem at the apex.

Leaf primordium: A small protrusion around the growth cone that is the original body of the leaf.

Young leaves: large protrusions around the growth cones that will form mature leaves in the future.

Axillary bud primordium: The protrusion that grows in the axils of young leaves and forms axillary buds in the future.

Scales: Surrounded on the outside of the bud, it plays a protective role.

1. When the flower buds grow, they are mostly skewed, and the relative leaf buds are round and rolling (the leaf buds are slightly flattened when they grow, and the leaf buds are also a few round, but they are also thin, and there are no flower buds thick and drumming).

2. There is a root under the leaf bud, and there is no under the flower bud (except for the flowers on the leaf). So you can dig a little bit and see if there are roots.

3. You can gently pinch it with your hands slightly, the flower buds are looser, and the leaf buds are harder.

The flower buds are thin and the leaf buds are bulging. The flower buds are in the front and the leaf buds are in the back.

Orchid (scientific name: cymbidium ssp.).）：

Epiphytic or terrestrial herbs, leaves several to many, usually born at the base of the pseudobulb or on the lower nodes, in two rows, banded or rarely inverted-lanceolate to narrowly elliptic, the base is generally broadly sheathed and encloses the pseudobulb, and the nodes are related. The racemes have several or multiple flowers, and the colors are white, pure white, white-green, yellow-green, light yellow, light yellow-brown, yellow, red, blue, and purple.

The orchid in the traditional Chinese famous flower only refers to several species of native orchids distributed in the Chinese orchid genus, such as Chunlan, Huilan, Jianlan, Molan and Hanlan, which are commonly referred to as "Chinese orchids". This kind of orchid is very different from the tropical orchid with large and colorful flowers, no eye-catching showiness, no huge flowers and leaves, but it has a simple and quiet, elegant and noble temperament, which is very in line with the aesthetic standards of the Orientals. It has been cultivated in China for more than 1,000 years.

There are also a few leaf buds that are garden, but they are also thin, and there are no flower buds in the thick garden drum. In addition, the leaf buds generally grow on the pseudobulb of the new bluegrass seedling, and the flower bud generally grows on the false bulb of the bluegrass seedling of the previous year.
