| 摘 要： | 选用生产上常用的4个杂交水稻不育胞质WA型、JW型、G型、K型与高配合力水稻保持系G46B转育形成一套同核异质二元系,在PEG模拟干旱胁迫处理下研究不育胞质对水稻抗旱生理的影响.结果表明:不同水稻不育胞质材料在干旱胁迫下各生理活性差异显著,胞质对核基因调控生理抗旱反应也存在明显差异;JW型等不育胞质在10 % PEG干...

| Abstract: | Four kinds of sterile cytoplasm of hybrid rice commonly in production,WA-type,JW-type,G-type and K-type,and high combining ability maintainer line G46B were used to transfer for binary system with nuclear heterogeneity.And effects of different kinds of sterile cytoplasm on drought resistance of rice were studied under simulated drought stress in PEG.The results showed that sterile cytoplasm of different rice under drought stress in the physiological activity was significantly different.The responses of cyto... |
