| 摘 要： | 1998年早季于广州,用两系法水稻高产新组合培矮64s/E32、培矮64s/9311、粤杂 122和常规高产品种粤香占、特三矮2号,研究了它们移栽后叶、鞘生长动态的差异。结果见到:（1）主茎上的出叶速度与其生育期长短相对应;（2）鞘长/叶长比例小对孕育大穗、提高结实率有利,“叶长鞘短”应属水稻高产育种中所寻求的一个重要指标。

| Abstract: | Three two-line rice hybrids Peiai 64s/E32, Peiai 64s/9311 and Yueza 122, and 2 inbred rice varieties Yuexiangzhan and Tesan'ai 2, were used to study the difference of growth dynamics of their blades and sheath in the early cropping season at Guangzhou. The results showed that (1) the emergence rate of leaves on the main culm accorded with the plant growth duration, the longer the growth duration, the faster the emergence rates of the leaves on the main culm; (2) the small ratio of sheath/blade length was helpful for the formation of large panicles and the increase of seed sets. 'Long blade and short sheath' should be one of the important targets for high yield rice breeding. |
