摘要
Abstract
In order to solve the problem of chilling damages of cold rice ,effect of low temperature on different genotypes rice varieties in Heilongjiang province was investigated ,total number of glumous flower and seed setting rate in artificial chilling conditions were analyzed .The results showed that the total number of glumous flowers were increased with the temperature rising ,different chilling conditions affect the total number of glu‐mous flower and seed setting rate .If the total number of glumous flower was more ,the seed setting rate was lower in three kinds of chilling temperature treatment .It was suggested that the effect of large capacity of rice varieties were more susceptible to chilling injury ,and then affect the final yield of rice .关键词
