Will long-term asexual reproduction of succulent plants lead to plant degradation?
Introduction to the core of the body: Knowledge of succulent plants and succulent plants, will long-term asexual reproduction of succulent plants lead to plant degradation?, The relevant content is as follows: Regarding the asexual reproduction and degradation of succulent plants, there is a question. For example, narcissus are triploid and can never have seeds. They have been asexual reproduction for thousands of years. Why hasn't it deteriorated so far? There are also some species that are not easy to bear seeds, such as naked lotus. As far as I know, they rely on cuttage propagation, so why doesn't it degrade?
First of all, I must explain that I am not a major in plants, so some expressions will not be rigorous enough. In addition, my understanding of some issues will be biased, and I often know what it is but don't know why.
In fact, many species in nature have the characteristics of asexual reproduction. Take succulent plants as an example. Kalanchoe daiggremontiana, a root-rooted plant of the genus Calamaria in the family Crassulaceae, is a very typical one. A large number of bulbules can grow into an independent individual and have a strong self-reproduction ability, which is why they have the name "root-rooted". I believe that all (C-S) people who take root in the market are asexual individuals. Of course, it can also bloom for sexual reproduction, but after most Crassulaceae flowers, the life span of the entire plant basically ends, so I have never seen it take root and bloom.
It can be seen from this that through nature's selection, different species will evolve unique ways to adapt to survival in nature, including the way to continue the race. In this case, it is naturally reasonable for some plants to evolve methods that can provide stable asexual reproduction. Narcissus are plants of the Lycoridaceae family and can grow large numbers of bulbs, enough to ensure the continuation of their species. Therefore, asexual reproduction of these species will not lead to degradation of traits.
However, there are also many plants that do not have the ability to reproduce asexually. Even if they can reproduce through cuttage and other methods, it is just that in nature, these plants do not use asexually reproduction as the main way to continue their species. For example, some cactus varieties rarely have large ones. Jinhu is one of them. What do they rely on to maintain the stability of the race in nature? It can only be sexual reproduction!
Nude Hu is a short-thorn variety of Jinhu. As far as I know, it is not difficult to bear seeds. However, this variety has to grow very big before it can blossom. When it blooms, it should not be difficult to harvest seeds. In addition, although I have never seen gold amber or naked amber seeds, based on the very cheap price of their seeds, they will not be rare.
As for degradation, it actually includes many aspects, and does not specifically refer to the external characteristics of the ball. Asexual reproduction is actually cloning, and its biggest feature is to maintain the maternal traits. The degradation I mean the quality of the breed. To give an unelegant example, due to the unhealthy lifestyle of modern people, isn't it that the sperm count of men is significantly lower than in the past? Hehe. Therefore, the so-called degradation is reflected in the difficulty in rooting roots, difficulty in blooming, poor disease resistance, etc. The most obvious thing is, can you still see the red balls from Fujian blooming?
So to sum up, when I say that long-term asexual reproduction leads to the degradation of species characteristics, I mean that varieties that were not originally dominated by asexual reproduction will inevitably lead to the degradation of the species due to a large number of asexual reproduction, especially deliberate, uncontrolled and excessive asexual reproduction. You can ask some flower friends who have raised tissue culture seedlings of Wale reed, and they will have a deep understanding of this, although Wale reed lateral bud reproduction is also asexual reproduction.
Of course, I do not deny the value of asexual reproduction itself, especially in saving endangered species, which still has its special significance.
Will long-term asexual reproduction of the succulent plants described in [] above lead to plant degradation? A comprehensive method to explain, hope that a throw a brick to attract jade can solve your problems in green plants bar.
