我省迟熟早稻及中稻中、后期的高温伤害是影响生产的一大障碍。高温对水稻的影响早已引起国内、外水稻育种和栽培工作者的关注。但是关于水稻抗热性的研究却开展得较迟,有关这方面的文献资料也不多,并且大多数研究工作都停留在形态学水平上。对于热害的研究进行较早且比较系统的是日本学者佐藤庚、西山岩男、松岛省三等,随后中国科学院上海植物生理研究所和武汉大学生物系等单位也分别在不同的条件下,从不同的角度对水稻热害的敏感期,临界温度,热害机理等问题进行了较深入的研究。现将他们的研究结果和笔者的一些看法综述如下。
Early maturing rice in our province and middle rice, late high temperature injury is a major obstacle to production. The impact of high temperature on rice has long aroused the concern of domestic and foreign rice breeding and cultivation workers. However, studies on the heat resistance of rice have been carried out relatively lately, and there are not many references in this field, and most of the research work remains at the level of morphology. For the study of thermal damage earlier and more systematic Japanese scholars Sato Geng, Xishanyan Matsushima third, followed by the Shanghai Institute of Plant Physiology, Chinese Academy of Sciences and Wuhan University Department of Biology and other units were also under different conditions, From different perspectives, we conducted a more in-depth study on the sensitive period, the critical temperature and the mechanism of thermal damage in rice. Now their findings and some of my observations are summarized below.
