作为一种单倍体育种技术,小麦花粉培养已被广泛采用。但是单倍体植株的加倍问题,仍然是花培中需要继续探讨和有待进一步解决的问题。采用秋水仙精处理单倍体植株。加倍率固然高一些;但是操作过程导致死苗伤苗现象难以避免。所以在花粉培养中单倍体植株的自然加倍,仍然是很多组培工作
As a haploid breeding technology, wheat pollen culture has been widely used. However, the doubling of haploid plants is still a problem that needs to be further explored and needs to be further solved in flower culture. Treating haploid plants with Colchicine. Although the doubling rate is higher; however, the operation causes the phenomenon of dead seedling and wounding seedling to be unavoidable. Therefore, the natural doubling of haploid plants in pollen culture is still a lot of tissue culture work
