对多年生豆科牧草包括苜蓿在内的硬实种子的研究,已有大量的专著。实验中取得的大量资料,得出了关于硬实种子产生的原因、条件及发展过程的明确概念,也找到了消除硬实种子的方法。硬实种子性状对于保存野生品种有明显的效用,但是有很多研究人员否认这种性状对栽培苜蓿的良好作用。在遗传育种方面对该性状的研究还很不够。为数不多的一些著作中,把注意力集中在怎样用育种方法来淘汰这种性状。在和的著作中对此问题阐述得较充分、全面。他们建
There have been numerous monographs on the study of hardy seeds, including perennial legumes, including alfalfa. A lot of data obtained in the experiment, come to a clear concept on the causes, conditions and development of hard seeds, but also found a way to eliminate hard seeds. Hard seed traits have obvious utility for preserving wild varieties, but many researchers have denied the good effect this trait has on cultivated alfalfa. The study of this trait in genetics and breeding is still not enough. In a few works, the focus is on how to eliminate this trait by breeding methods. This issue is more fully and comprehensively described in his work. They built
