摘要
为探讨羊草有性繁殖能力极低的原因 ,不同学者曾研究了性细胞发育、气候变化、营养条件和其它各种干扰因素对羊草有性繁殖的影响 ,在综述以上各方面研究进展的基础上 ,对进一步研究提出了一些初步看法。
Leymus chinensis is a rhizomatous herbage.It was reported that the sexual reproductivity of this species is very low,the sexual reproductivity could be influenced by the development of pollen cell,the change of climate,the absorption of nutrition,the disturbance of men and animals.This paper summarized earlier studies about the low sexual reproductivity and provided some suggestions for further research on improvement of the sexual reproductivity.
