番茄在低温弱光下生理特性的变化研究

Studies on the Physiological Characteristic of Lycopersicon esculentum Mill at Low Temperture under Low Irradiance

通过对2种不同的杂交一代番茄进行低温弱光(5℃、100μmol.m-2.s-1)处理5 d后,与未处理时(0 d)相比较。结果表明:其超氧化物歧化酶(SOD)活性会降低,丙二醛的含量、可溶性糖的含量会升高,叶绿素的含量则呈现出前3 d降低,后2 d升高的变化。

After the seedlings of two tomato being exposed in chilling stress under low irradiance（5℃ ; 100 μmol · m^-2 · s^-1 ） for five days , contrast to no stress（O d）. The SOD activity of plant decreased,the content MDA and soluble sugars are increased, the content of chloropyll decreased after the stress for three days, but increased in the forth day.
