| 摘 要： | 通过3H-葡萄糖标记示踪，盆栽条件下研究干旱对水稻灌浆期间贮存同化物再分配的影响。分蘖末期用3H-葡萄糖标记水稻最上部完全展开叶，在扬花期时标记3H主要积累在鞘和倒二叶中。从扬花期到成熟期水稻穗部的放射性活度增加主要来源于鞘和剑叶，常规水稻高于旱作水稻。扬花期旱作水稻非结构性标记物较多，但灌浆期间向籽粒转运和再分配过程中的转化效率远低于常规水稻。

| Abstract: | ~3H-glucose trace technique were applied to rice to study the response the redistribution of reserved-assimilate to aerobic condition at seed-filling stage.Labelled the top full-opened leaf at late tillering stage,the mark stored mainly in sheath and the second leaf from the top at flowering stage.The source of radioactivity in spike came mainly from sheath and the top leaf from flowering to mature stage,and the radioactivity in spike of paddy rice was more than aerobic rice.There was more non-structural ma... |
