旱后复水对水稻生长的后效影响（Aftereffects of Rewatering after Water Stress on the Rice Growth）
水稻 水分胁迫 复水 后效性
2010/12/29
通过盆栽和测坑试验，研究了水分胁迫后复水对水稻生育后期的后效性影响。结果表明：水稻前期旱后复水后效性明显，尤以分蘖末期短历时重旱、拔节初期短历时轻旱后效性最佳。前期适度的胁迫后复水使水稻后期保持了较大的光合面积，明显降低生育后期叶绿素的降解，使功能叶在生育后期维持较高的光合效率，有利于干物质累积。

We examined the responses of doubled-haploid lines (DHLs) of rice (Oryza sativa L.) to drought and rewatering in controlled rainfed lowland conditions, to test the the hypothesis that the DHLs would p...
水分胁迫及复水对水稻冠层结构的补偿效应（Compensation Effects of Water Stress and Rewatering on the Structure of Rice Canopy）
水稻 水分胁迫 复水 冠层结构 补偿效应
2010/4/1
通过盆栽和测坑试验，研究了水分胁迫及复水对水稻冠层结构的补偿影响。结果表明：水分胁迫在抑制水稻茎秆、叶片、叶面积延伸生长的同时，能有效地诱导冠层结构，为旱后复水补偿效应的产生提供条件。旱后复水促进了后期穗节的伸长、延缓后期叶片衰老速率、苗后期胁迫使作物对再次受旱的适应能力增强。但补偿效应是有条件的，苗后期重旱和拔节初期轻旱补偿效应最佳，应避免两阶段连旱和拔节期重旱。 Research was ca...
