浙江省主栽水稻品种种子活力鉴定与评价
|
摘要
以浙江省主栽的常规籼稻、常规粳稻、籼粳杂交稻各3个品种种子为材料,比较了标准发芽试验、耐旱性测定、耐涝性测定以及模拟大田试验4种活力测定方法,并将试验结果进行了聚类分析和相关性分析。结果表明,不同水稻品种种子活力差异显著,籼粳杂交稻品种种子活力较好,为高活力种子类型,其中,甬优1540的活力最佳;常规稻品种种子活力均较弱,可为中、低活力类型,其中中早39的活力最低。相关性分析结果发现,淹水发芽指数与所有指标均呈显著相关关系,因此,本研究认为淹水发芽指数是评价水稻种子活力的最有效指标。
In the present study,three kinds of conventional indica,japonica and indica-japonica hybrid rice varieties were used to evaluate four seed vigor testing methods,including standard germination test,drought tolerance test,waterlogging resistance test and simulated field experiment.Cluster analysis and correlation analysis were carried out for the data obtained.The results showed that there were significant differences in seed vigor among different rice varieties,the seed vigor of indica-japonica hybrid rice varieties were better than other varieties,especially Yongyou 1540,which had the highest vigor;whereas the seed vigor of conventional rice varieties were lower,especially Zhongzao 39,which showed the lowest vigor.The correlation analysis showed that the waterlogging germination index was significantly correlated with all the indices,therefore,it was suggested that waterlogging germination index was the most effective index for evaluating rice seed vigor.
