摘　　要：低温条件下对不同地区的多个优质水稻品种进行分蘖盛期冷害鉴定试验,研究结果表明,龙稻18和通育269品种耐冷性表现强,上育397、通35等3个品种耐冷性表现中。分蘖盛期耐冷性表现优异品种其保护酶活性(SOD、POD)增加明显,多数品种酶活性与其耐冷性表现成正相关。Under low temperature condition,the chilling damage identification test was carried out on several high quality rice varieties in different regions at the peak tillering stage.The results showed that Longdao-18 and Tongyu-269 showed strong cold tolerance,while Shangyu-397 and Tong-35 showed moderate cold tolerance.The activities of protective enzymes(SOD and POD)increased significantly in the high tillering stage,there was a positive correlation between enzyme activity and cold tolerance in most varieties.
