摘　　要：为深入细致地研究黑龙江省水稻冷害生理机制,介绍了全世界种植水稻的110多个国家中大约有24个国家经常遭受冷害的威胁。我国从南到北种植水稻的省份,也不同程度上遭受冷害带来的产量损失,黑龙江省是水稻冷害发生最为严重;分析水稻发生冷害的原因是细胞器发生结构上的改变,酶、激素和其它生理指标根据不同程度的冷害而发生浓度变化;指出当前黑龙江省水稻冷害发生类型主要是孕穗期障碍型冷害;提出深入系统研究黑龙江省水稻冷害生理机制的研究思路。In order to study the physiological mechanism of rice chilling injury,there were 110 countuies planting rice,about 24 countries in them were harmed by chilling injury.Rice yield was reduced when chilling injury was occurrened in provinces of planting rice in China,Heilongjiang province was the most serious province of chilling injury;The cause of rice chilling injury were the structure change of organelles,the concentration change of enzymes,hormones and other physiological indexes;The main chilling of Heilongjiang was sterile-type chilling injury at booting stage;The research approach of physiological mechanism for chilling injury in Heilongjiang province was put forward.
