摘要
对粳型不育系津3A的日开颖比率、午前花率等开花习性进行了初步研究,结果表明:津3A开花历期约为7d,始花后第2天即进入盛花期;每日11:30—12:30为盛花时间,比C418约迟30min,在制种中应该注意适当喷施花时调节剂,提早津3A花时,使父母本盛花期、盛花时相遇,提高制种产量。
The preliminary observation on the flowering habits of Jin 3A a new Japonica male sterile line was studied involving the rate of spikelets daily opening and the rate of flowering before noon. The result showed that the florescence could last for 7 days. The number of spikelets opening increased remarkably from the second day. And the full blooming time,from 11:30 to 12:30,began later than that of C418 about 30 minutes. Some measurement must be taken to advance the flowering habits of Jin 3A and to improve the yields of seed production.
