An Analysis of all kinds of nouns in the Genus of Twelve volumes introduction to Science Popularization of succulent plants

Recently, there was another real life tearing: a sold a plant temporarily called black muscle solid plant to BMagneB who was very happy to receive the goods. He should show it to other people who understood it, and found that it was not a pure black muscle at all, but a hybrid string. He was upset and asked the seller to return 300 yuan, but the seller did not agree. (thank you for the non-immortal material.)

Ben Xiaoxian and everyone discussed the concepts of real life and so on as follows. Welcome to correct and supplement ~ hope to be a clear concept in the future.

There is only one kind of seed, and the seed sows and grows. The seed of so-and-so indicates that this variety is the seed of the female parent.

For example, writing music in real life means that the mother is writing music. Of course, this source of writing music as the mother must come from all kinds of asexual reproduction. Whether it's tissue culture or leaf insertion or lateral buds.

Furthermore, there is only one real-life writing music, that is, the named one. If someone else hybridizes and obtains it in the same way, you can add the last name before it. Like Yamamoto.

For example, Bai Miao, the real half-wild Bai Miao, there is only one plant.

Many people called Bai Miao Shisheng are not Bai Miao. Bai Miao Shisheng is the first generation of Bai Miao as the female parent. Many traders will take advantage of this loophole, because many people will mistakenly think that so-and-so is a real object.

Volume 12 is matrilineal society. The offspring of the female parent of the inscription is called the department.

For example, write music department, write music as the offspring of the female parent, and these offspring as the offspring of the female parent.

The difference from the real life mentioned above is algebra.

The lateral buds are asexual reproduction, and the lateral buds are not. The characters of lateral buds were expressed early and sturdy. After planting, it will also go through the process of character decline and strength.

The female parent is A, written in front, international practice.

Indicates that it is obtained by leaf insertion.

If a real leaf is inserted, it means that her mother is a real person. Of course, this is also very rare, especially the inscription.

Generally do not emphasize the seedling, the female parent is the leaf insertion of all kinds of asexual reproduction seedlings. For example, the leaf insertion of leaf cuttings, the leaf insertion of tissue culture seedlings and the leaf insertion of lateral buds are all called leaf cuttings.

Leaf cuttings are also usually stronger (except those obtained with hormones).

Like lateral buds and leaves, both belong to asexual reproduction. All the characteristics of the maternal parent can be integrated, of course, there is also the possibility of variation. For example, the super green island was cultivated in R2. Watermelons were cultured in red stripes, and Kongming lanterns were cultured in OB.

Variation is always there, there will be real life, and there will be asexual reproduction. Of course, variation has two directions: good and bad. Only with variation can there be inscription brocade or new products produced by tissue culture as mentioned above. Mingpin brocade is a variation produced in the process of asexual reproduction. The variation is shown in many aspects, such as grain, body shape, brocade and so on.

For example, the Baimiao variation of tissue culture in Shenyang (which has not yet been named) has green lines; the super green island in tissue culture of R2 is large and the lines become thicker; and watermelons in tissue culture of Hongqingshou show a back window.

The flowering plants may also maintain the grain of the female parent, or there may be some changes. You can only see it when you grow up.

The way of artificial intervention promotes variation. Radiation is commonly used or mutagens such as colchicine are added. These methods need not be too exclusive, because they have been used in agriculture for a long time. The price is also high. For example, if you irradiate the seeds with radiation, a large part of them will die.

Famous such as Yanda embryoid body induction technique (I don't understand fine lines), which can not only maintain the characteristics of famous products, but also produce brocade at the same time.

I just don't grow up. Both external environment and self-factors can lead to rigid seedlings. For example, improper care of seeding seedlings may lead to stiff seedlings; leaf insertion and tissue culture obtained with excessive hormones may cause stiff seedlings.

Answer three questions

1. Stiff seedlings, how can you tell? Many seedlings have been collected, and sellers say that they are dehydrated on the road or have been dehydrated for a period of time before delivery, or that the planting has not yet recovered. So is there any way to tell whether it is a rigid seedling in the first place?

2. excluding hormone problems, is it the highest probability of stiff seedlings in tissue culture?

3. How to distinguish the quality of tissue culture plantlets?

1. Stiff seedlings can be judged by some experience that they grow obviously slowly and hardly grow. The first time you can't tell the difference, you have to plant it for a while. I also talked about external and internal causes before. Rigidity caused by external causes can be avoided by veterans. So if a veteran complains that it is a rigid seedling, nine times out of ten, it will be the problem of Miao itself.

2. In general, tissue culture seedlings are weaker than leaf cuttings and lateral buds at the seedling stage. However, if the technology is good, it can be handled well, such as a large tissue culture that has been raised.

3. I look at the producer, or I try to grow it myself. Generally speaking, it doesn't matter whether the seedlings are cultured or not, they are all the same when they are brought back.
