氯化钙对坝亚7号亚麻种子萌发及幼苗活力的影响
Effect of CaCl2 Priming on Seed Germination and Seedling Vigor of Sub-7
【摘要】 为了提高干旱条件下亚麻种子的发芽率和幼苗活力,以坝亚7号为供试材料,采用PEG模拟干旱胁迫,不同氯化钙溶液引发坝亚7号种子,研究其在干旱胁迫条件下的萌发特性和幼苗活力。结果表明:氯化钙处理可提高坝亚7号种子种子的发芽势、发芽率、萌发指数和幼苗活力,氯化钙最适处理浓度为0.5g/L和1.0g/L。
【Abstract】 In order to improve the seed germination rate and seedling vigor of flax varieties on the drought conditions,Sub-7variety was taken as the material,the seed germination characteristics and seedling vigor were studied on drought stress condition by using PEG to simulate drought stress and CaCl2 priming.The results showed that seed germination potential,germination rate,germination index and seedling vigor were improved by CaCl2 priming.The optimum concentration of calcium chloride trigger were 0.5g/L and 1.0g/L.
