摘要
以宁夏日光温室栽培常用的番茄品种"以色列168"幼苗为试材,通过智能人工气候箱模拟设施生产中的昼/夜温度为24℃/11℃、21℃/8℃、18℃/5℃3个亚适温环境,比较了不同温度条件下番茄幼苗丙二醛、脯氨酸、电导率和过氧化氢酶4个生理生化指标的变化。结果表明:与适宜温度CK(28℃/15℃)生长的植株相比,T1处理(24℃/11℃)的番茄幼苗能适应至少10d的亚适温环境,T2(21℃/8℃)处理的番茄幼苗在经历了8d的亚适温环境后适应力增强,T3处理(18℃/5℃)的番茄幼苗经历6d亚适温环境后生长力下降。
Taking ＇Israel 168＇ tomato seedlings as materials,using the intelligent artificial climate box to simulate 3 suboptimal temperature environment（Day/Night 24℃/11℃,21℃/8℃,18℃/5℃） in production facilities,MDA,proline,electric conductivity and catalase four physiological and biochemical indexes of tomatoes under different temperature were measured.The results showed that,compared to the plant growth in the appropriate temperature CK（28℃/15℃）,T1 treatment（24℃/11℃） of tomato seedlings could adapt to suboptimal temperature environment at least 10 d,T2 treatment（21℃/8℃） of tomato seedlings adaptability enhancement after 8 d suboptimal temperature environment,T3 treatment（18℃/5℃） of tomato seedlings growth declined through 6 d suboptimal temperature environment.
