First, vegetative reproduction is apomixis, which can make a highly successful genotype last forever without complicated sexual processes such as gene recombination, flower bud differentiation, flowering and fruiting, and this highly successful genotype is often unable to be inherited due to sexual sterility. Secondly, the vegetative reproductive organs usually begin to appear at the seedling stage, which is earlier than flowering, has a single growth period and simple environmental conditions, and does not need special ecological conditions needed for flowering and fruiting. Thirdly, apomixis can produce a large number of individuals with the same genotype. At the same time of vegetative growth, it can continuously produce new plants, expand individuals, occupy space, seize water and nutrients, and has more growth advantages than seed reproduction. Fourthly, the whole clone is a whole in physiology, and its parts are connected with each other. It is of great value to transport water, assimilates and hormones to developing or sprouting buds or poorly positioned parts, which is of great value for competition and accelerating recovery after injury.
