钠、钾和钙离子对小麦幼苗叶片质膜透性和组织活力的效应
Effects of Na+, K+ and Ca2+ Ion on Plasma Membrane Permeability and Tissue Vigor of Wheat Seedlings Blade
【摘要】 在等渗和等阴离子有效浓度条件下。 Ｎａ＋和 Ｋ＋的单独效应都使小麦幼苗叶片的质膜透性增大。且Ｎａ＋＞Ｋ＋，而 Ｃａ２＋的单独效应却使其减小； Ｋ＋和 Ｃａ２＋的单独效应都使小麦叶片组织 ＴＴＣ还原率增大．且Ｃａ２＋＞Ｋ＋，而Ｎａ＋的单独效应却使其减小。
【Abstract】 Na+ and K+ both independently increased plasma membrane permeability of wheat seedlings blade at the effective consistence of the isosmotic and negative isoionic. and the effect of Na+ is greater than that of K+, but independent effect of Ca2+ is decreased. Under the same conditions. K+ and Ca2+ both independently increased TTC reducing rate of wheat blade tissue, and the effect of Ca2+ is greater than that of K+. but independent effect of Na+ is decreased.
