以3个杂交水稻品种不同活力水平的种子批为试验材料,比较了标准发芽试验、低温发芽测定和高温催芽试验3种活力测定方法,并将试验结果与田间成苗率进行相关性分析,发现标准发芽试验的发芽指标、低温发芽10 d的发芽率和高温催芽后的发芽率均与田间成苗率存在显著正相关关系,且高温催芽后的发芽率与田间成苗率相关系数最高。研究结果表明,高温催芽法可以作为杂交水稻种子活力测定的有效方法。

Ab strca t:In the present study , three hybrid rice cultivars with different vigor levels were used to evaluate three seed vigor testing methods , including standard germination test , low temperature germination test and high temperature pre-germination test .The results of three methods were correlated with the results of seedling percentage in field .The results showed that germination indexes of standard germination test , germination percentage on the 10th day of low temperature germination test and germination percentage of high temperature pre-germination test were all significantly positively correlated with seedling percentage in field .Besides, correlation coefficient between germination rate of high temperature pre-germination test and seedling percentage in field were the highest .The results suggested that high temperature pre-germination test was an appropriate seed vigor method for determination of rice seed vigor .
