不同大豆种子萌发期耐盐性分析
|
摘要
为探究大豆萌发时耐盐性差异,选取栽培大豆晋大53和野生大豆平南,设置多种NaCl溶液浓度对发芽过程进行胁迫处理,选取胁迫对发芽性状影响最适的差异浓度,对13种大豆材料进行耐盐性鉴定。结果表明,NaCl溶液浓度200 mmol/L为盐胁迫的最适浓度;与对照相比,盐胁迫下大豆种子的发芽率、发芽势、发芽指数和活力指数明显降低,而不同大豆材料受胁迫影响差异显著,材料间各指标也具有一定差异。综合来看,在13种大豆材料中,SNSZ177,SNSZ266为耐盐材料;SNWS93,SNWS265为不耐盐材料;其余为中等耐盐材料。
To explore the differences of salt tolerance of soybean at germination stage, Glycine max Jinda 53 and Glycine soja Pingnan were selected to screen the optimum stress concentration using different salt concentration gradient, 13 soybean materials were identified using the optimum stress concentration and control. The result showed that the optimum concentration of salt stress was200 mmol/L NaCl. Compared with the control, the germination percentage, germination potential, germination index and vigor index of salt stress decreased significantly. Different soybean materials were significantly different under stress, and there were some differences among indicators. SNSZ177, SNSZ266 were salt-tolerant materials, SNWS93, SNWS265 were non-salt-tolerant materials, and the rest were medium salt-tolerant materials.
