Perhaps the short-day treatment of SD is necessary to the fertility.(2): Compared the 88-428 SD(14.8-15.2h/d) with the 88-428 LD(14.9-15.3h/d), a new isozyme band of Rf=0.19 was found for the first time in the leaves of the 88-428 SD from the branching.

大豆光敏雄性不育材料88-428在出苗后经过连续20天的短光照处理后，与长光照条件下的88-428相比，从分枝期起多了Rf=0.19的酶带，特别值得指出的是Rf=0.19的酶带在以后的发育时期内一直存在，说明经过短光照的诱导以后产生了新的物质，而且这种物质可以在细胞间运输，影响到植株的生殖生长。

In any case, technologies for assisted reproduction cost thousands of dollars. So public health systems usually do not offer them.
