| 摘 要： | 在大田条件下，对水稻茎基伤流量、穗颈伤流量与产量库及群体质量的关系进行了研究。结果表明，颖花穗颈伤流量与粒叶比、抽穗至成熟期积累的干物量关系密切，颖花茎基伤流量与实粒数／ｃｍ＾２（叶）、粒重／ｃｍ＾２（叶）关系密切。颖花伤流量可作为水稻经济产量形成期源库关系的质量指标。 |

| Abstract: | The bleeding intensity at basal internode and neck panicle node and the relations of bleeding intensity with yield sink and population quality of rice were studied in the field culture experiments.The results indicated that the spikelet neck node bleeding intensity was closely related with grain leaf ratio and accumulation of dry matter from heading to mature,and so were the spikelet basal internode bleeding intensity with the filled spikelet leaf(cm 2)ratio and the grain weight leaf(cm 2)ratio.The spikelet bleeding intensity could be used as a quality index for the relationship of source and sink after heading. |
| Keywords: | rice spikelet bleeding intensity population quality |
