摘要
试验了不同浓度的ＣａＣｌ２、Ｃａ（ＮＯ３）２和ＣａＳＯ４三种钙盐对大豆（晋豆１号）生长前期盐胁迫的缓冲效应，结果表明：ＣａＣｌ２、ＣａＳＯ４都有明显的缓解作用，其中以１５ｍｍｏｌ／ＬＣａＣｌ２的缓解效果最佳。Ｃａ２＋能提高大豆萌发种子的蛋白酶和脂肪酶活性，提高呼吸速率。
The mitigative effects of three kinds of Ca 2 + solution (calcium nitrate, calcium chloride and calcium sulfate) with different concentrations on salt stress in the early stages growth of soybean were tested. The results showed that calcium chloride and calcium sulfate were better to mitigate salt stress of soybean growth, while the effect of 15 mmol/L calcium chloride was the best. Calcium could increase the activities of proteinase and lipase in germinating of soybean seeds, enhance the respiratory rate, improve the germinating capacity and promote the growth of radicle.
