| 摘 要： | 对黑龙江省不同熟期的21个水稻品种进行低温胁迫研究,以水稻死苗率作为评价指标,分析得出不同熟期水稻的死苗率中熟品种晚熟品种早熟品种,各低温胁迫条件下以3℃/13 d处理21个水稻品种死苗率在0～100%分布最为均衡。

| Abstract: | 21 rice varieties of different maturity in Heilongjiang province were studiet under the low temperature stress.Taking dead seedling rate as indicator,the result showed that the dead seedling rate of different maturity was mid-maturing varieties〉late-maturing varietiese〉arly-maturing varieties,the dead seedling rate of 21 varieties was the most balanced distrbuted in 0～100% under the treatment of 3℃ lasting 13 days. |
