摘要
以玉米(鲁玉11号)为实验材料.分别用150mmol/LNaCl,150mmol/LNaCl+15mmol/LCaCl2及150mmol/LNaCl+15mmol/LCa(NO3)2的1/2浓度Hoagland溶液连续处理5天后,分别测定MDA含量、质膜透性、植物鲜重、植物干重及植物体内Na+含量.实验结果表明,NaCl严重地抑制玉米的生长,而CaCl2和Ca(BO3)2均能降低由NaCl引起的抑制效应,且Ca(NO3)2优于CaCl2此外,NaCl增加细胞质膜透性、植物体内Na+和MDA含量CaCl2和Ca(NO3)2降低质膜遍性,减少植物体内Na十和MDA含量,Ca(NO3)2的这种效应好于CaCl2.
Corn (Zea mays'L.Luyu 11)has been traied by 150 mmol/L NaCl, 150 mmol/LNaCl+15 mmol/L CaCl2, 150mmol/L NaCl+15mmol/L Ca(NO3)2in 1/2 Hongland solution for 5 days respectivelys MDA, permeability of plasma membrane,dry weight, fresh weight and concentration of Na+ in plants were determined after treatments. Results show that NaCl seriously inhibits the growth of corn,CaCl2 and Ca(NO3)2 have lowered the inhibition effects induced by NaCl.Besides,NaCl has increased plasmalemma permeability and the content of Na+ as well as MDA in plants. CaCl2 and Ca(NO3)2 have lowered plasmalemma permeability,while the content of Na+ and MDA has decreased, and the effect of Ca(NO)2,is bettr than that of CaCl2.
