水稻孕穗期耐冷研究展望

Advances in Research of Cold Tolerance at Rice Booting Stage

水稻对低温较为敏感,尤为孕穗期阶段,如遇低温冷害则导致产量显著降低。文章从水稻耐冷机制、孕穗期冷害鉴定方法和评价指标以及孕穗期QTL定位等三个方面总结分析孕穗期耐冷研究成果,明确国内外研究进展,并对今后水稻孕穗期耐冷性的研究提出了展望。

Rice to low temperature sensitive,especially the booting stage,in case of low temperature chilling injury are significantly reduced their yield.In view of this,from the mechanism of cold tolerance in rice,booting stage chilling injury appraisal methods and the evaluation index and booting stage QTL mapping and so on four aspects to analyze booting stage cold tolerance research results,a clear research progress both at home and abroad,and cold resistance of rice booting stage f or the future research prospect was put forward.
