【摘要】 在长沙地区的自然温光条件下，安农Ｓ—１—６、衡农Ｓ—１、Ｗ７４１５Ｓ、１３５６Ｓ、１３７６Ｓ、 １４０２Ｓ和衡农Ｓ— ２属温敏类型； Ｎ—１０Ｓ和Ｎ—１３Ｓ属反温敏类型，农垦５８Ｓ、 ３１１１Ｓ、５０４７Ｓ和５０８８Ｓ的育性主要由光照长度控制。安农Ｓ－１—Ｇ、１３５６Ｓ和Ｗ７４１５Ｓ全败育的临界日均温为２７℃，衡农Ｓ—１、１３７６Ｓ、１４０２Ｓ全败育的临界日均温为２９℃ ； Ｎ—１０Ｓ和Ｎ—１３Ｓ全败育的日均温为２４．４℃以下。农垦５８Ｓ、３１１１Ｓ、５０４７Ｓ和５０８８Ｓ由不育向可育转换时敏感期的日均温为２８．７℃，光强大于５０ｌｕｘ的光长为１３小时３７分。更多还原

【Abstract】 Under the natural light and temperature conditions in Changsha .An-NongS- 1 - 6, Heng -NongS-1, W7416S, 1356S. 1376S, 1402S and Heng-NoneS- 2 belong to temperature sensitive type, N-10S and N-13S belong to advise temperature .sensitive type. and the fertility of None-keng 58, 3111S 6047S and 6088S is controlled mainly by the light duration. The critical daily mean temperature for complete abortion is 27℃ for An-Nongs- 1 - 6. 1356s and wT415s. 29℃ for Hens-Nongs- 1, 1376s and 1402s and 24℃ for N10-S and N-13S. The condition under which Nong-keng 58s 3111s, 5047s and 6088s transform from sterility to fertility is that the daily mean temperature is 28.7℃ and the light duration(light intensity >50 lux)is as long as 13 hours and 37 minutes.更多还原
