利用某些植物营养体的一部分进行无性繁殖,可以保持母体的遗传特性,使后代形成整齐一致的无性系,这是加速植物优良品种的发展的一种重要手段。但是无性繁殖往往会带来严重的病害,主要是病毒一类的病害。因此,在生产上必须引起特别的注意。病原菌的传播途径引起植物病害的病原菌有真菌、细菌、病毒、还有类似病毒的支原体(又叫菌质体)等。真菌是危害植物的主要病原菌,它的危害部位一般是局部性的,生命周期比较短。病毒危害一般是整株性的,对于多年生的木本植物,
Cloning vegetative parts of some plants for asexual reproduction can maintain the genetic characteristics of the mother and make the offspring a clonal clone. This is an important means of accelerating the development of fine varieties of plants. However, asexual reproduction often leads to serious diseases, mainly virus-like diseases. Therefore, in the production must pay special attention. Pathogen transmission Pathogen causing plant diseases are fungi, bacteria, viruses, and similar virus mycoplasma (also known as the bacterial body) and so on. Fungi are the main pathogenic bacteria that endanger plants. The harmful parts of them are generally localized and the life cycle is relatively short. Virus damage is generally whole plant, perennial woody plants,
