| 英文摘要 | 从光敏核不育水稻“农垦585“幼穗分化至二次枝梗期开始，在每天的短日照光期（10H日光）结束、暗期开始时（EOd）进行15d的远红光（fr）照射实验，以比较开花、育性转变过程对短暂的远红光（fr）或红光（r）的反应。EOdfr明显抑制水稻植株开花（穗分化），导致“农垦585“和原种“农垦58“的抽穗期均比短日照下推退7d，表现为长日照效应，而“农垦58S“的结实率与原种相比却无显著变化。这暗示诱导农垦58S开花、育性转变过程的光反应可能有差异，前者不仅与光周期有关，且受EOdfr的剧烈影响，而育性主要受光周期（临界暗期）控制，基本上不受EOdfr的调控。; Photoresponses of flowering (panicle development) and fertility alteration of photoperiod-sensitive genie male-sterile rice "Nongken 58S" were compared after brief end-of-day (EOD) far-red light (FR) or red light (R) irradiation.From secondary rachis-branch primordia differentiation on, EOD experiments were Performed following 10 h of natural sunlight for successive 15 d.The heading date of "Nongken 58S"plants delayed for 7 d (long-day effect) by EOD FR,whereas its fertility had little or no change relative to the original-line rice "Nongken 58".These results implied that in" Nongken 585" plants photoperiod response mediating fertility alteration somewhat differed from that required by flowering.; 国家自然科学基金!39800087 |
