摘要
通过比较培矮64S、1356S、博A、安农S─1、明恢63和G67的开花习性,发现培矮64S具有柱头受粉面积小,颖花开闭时间较短,柱头生命力下降快,柱头外露率较高,花期和花时集中,与父本同步开花比率较高等特点。并就提高培矮64S的制种产量进行了讨论。
Pei’ai 64S had smaller stigma dimensions for receiving pollens, shorter glume opening period,lower stigma vitality and higher stigma exsertion percentage,compared with 1356S, Bo A,Annong S─1,Minghui 63 and G67.Its flowering period and hour were found more concentrated and synchronous withmale parents。 It was also discussed about how to increase the yield in the F1 seed production of Pei’ai 64S.
