摘要
以抗寒性不同的3个茄子品种为试材,研究了不同浓度的CaC l2(10,25,40 mmol/L)对其抗寒性的影响。结果表明,不同浓度的CaC l2处理后,各品种植物体内的SOD,POD,CAT活性升高、可溶性蛋白质含量增加;除荷苞长茄经40mmol/L的CaC l2处理的MDA含量增加外,其余浓度处理的各品种都降低。CaC l2对美国红茄的抗寒性影响最大。不同浓度对抗寒性的效果来看,10 mmol/L的CaC l2处理效果最好。
CaCl2 at 10, 25 and 40 mmol/L was used to treat eggplant seedlings. CaCl2 raised SOD, POD and CAT activities and soluble protein of the seedlings and decreased MDA contents in all the varieties studied with the exception of Hebaochanghqie treated with CaCl2 at 40 mmol/L. The greatest effect of CaCl2 was noticed in the American eggplant variety Meiguohongqie. Of the 3 concentration used, 10 mmol/L gave the most satisfactory result.
