摘要
观察结果表明 :光温敏核不育系“635s”单株的开花历期平均为 1 5 .5d,开花高峰期出现在抽穗后第 5～ 1 0d;在盛花期内全天 6∶0 0～ 1 9∶0 0均可开花 ,且在 1 1∶0 0～ 1 3∶0 0出现一个开花高峰 ,有时在 7∶0 0左右还出现另一个开花高峰 ;“635s”的柱头外露率达73.7% ,异交结实率达 5 9.1 % ,颖花张开时间为 2 .1 3～ 3.2 5h。
The observation results show that the single-plant of photo-thermo-sensitive genic sterile line “635s” has long flowering duration (15.5d on average) and obvious peak flowering period (on the 5th～10th day after heading); during peak florescence, the glume can flower at 6∶00～19∶00 in a day, and one peak flowering occurs at 11∶00～13∶00, sometimes the other peak flowering appears at 7∶00 or so; the rate of outshowing stigma of “635s” is 73.7%, its setting rate of outcrossing is 59.1%, and the opening time of the glume is 2.13～3.25h.
