燕麦种子抗盐碱特性研究
|
摘要
为了研究不同品种燕麦种子抗盐特性,本试验通过配置浓度为0(对照)、1.5g/kg(低)、2.5g/kg(中)、3.5gl/kg(高)的NaCI盐溶液,接种6个燕麦品种种子测定,发芽率、发芽势、胚根长和胚芽长等,几方面指标探讨了燕麦种子的抗盐特性并筛选出抗性较强的燕麦品种。结果表示:(1)盐分对燕麦种子的萌发有一定的抑制性。(2)基于发芽率、发芽势、胚根长、胚芽长的特性函数值-隶属值可知6个燕麦品种中对照组的发芽率整体高于实验组浓度增加后所有品种燕麦发芽率都呈下降趋势,牧王和领袖的抗盐碱型最高,贝勒2和爱沃耐盐碱型最弱。
In order to study the salt tolerance of different varieties of oat seeds,the seed germination rate,germinating potential,radicle length and radicle length of 6 oat varieties were tested by using NaCI salt solution with concentration of 0(control)of 1.5 g/kg(low concentration of 2.5 g/kg).Several indexes were used to study the salt tolerance of oat seeds and to screen the oat varieties with strong resistance.The results showed that:first,salt had a certain inhibition on the germination of oat seeds.2.Based on the characteristic function value of germination rate,germinating potential,radicle length and germ length,six oat varieties can be known.The germination rate of the middle control group was higher than that of the experimental group.The germination rate of all the varieties showed a downward trend after the increase of the concentration of the experimental group.The salt-alkali resistance of Liangwang and its leaders was the highest,and the salt-alkali tolerance of Baylor 2 and Avo was the weakest.
