通过实验室水培方法对油菜种子耐盐性快速筛选的研究

Rapid Screening of Salt Tolerance of Rapeseed by Laboratory Hydroponics Method

通过实验室水培的方法,测定不同油菜品种在不同浓度NaCl配制的营养液中芽期和苗期的农艺性状指标,并通过多元统计分析,对油菜的耐性进行鉴定评价。结果表明:在实验室盐油杂3号和秦优10号种子在高盐萌条件下计算得到的综合耐盐性D值要显著高于其他品种的D值,说明这两个品种受到的盐害较小,适合沿海高盐碱地区的大面积种植。

In this research,the agronomic traits of different rapeseed cultivars in the germination and seedling stages of different concentrations of NaCl were determined by laboratory hydroponic method,and the multi-statistical analysis formula was used to identify and evaluate the tolerance of rapeseed.The results showed that the comprehensive salt tolerance D of the seeds of Yanyouza 3 and Qinyou 10 in the laboratory was significantly higher than that of other varieties,indicating that the salt damage to these two varieties was smaller.These two varieties are suitable for large-scale planting in coastal high salinity areas.
