摘    要:研究了低温弱光对13个番茄品种苗期生长的影响,并对不同品种耐低温弱光性能进行了比较。结果表明:低温弱光下番茄幼苗的生长量、叶片叶绿素含量、光合速率下降;根系活力与细胞质膜相对透性变化,不同品种表现差异明显。综合比较,以黄洋梨、黄矮、马纳佩尔、紫玫瑰耐低温弱光能力较强,红洋梨、红矮、花绣球、红樱桃耐低温弱光能力较弱。植物体内发生的生理反应与植物的生长情况基本一致。幼苗生长量、叶片电导率、叶绿素含量、光合速率等,可以作为番茄苗期低温弱光抗性指标,几项指标应互相参照。

关 键 词:番茄  低温弱光  幼苗生长

Abstract:The authors studied the influences of low temperature and poor light on physiological character of the seedlings of 13 tomato varieties and identified the different tolerance of these varieties to low temperature with poor light.The main results showed that,at low temperature and poor light,there were significant differences among these varieties for the tolerance of the following varieties such as Huangyangli,Huang'ai,Manapei'er ect.were stronger than that of Hongyangli,Hong'ai,Huaxiouqiu and so on.The growth increment of seedlings,leaf conductivity,chlorophyll,content and photosythetic rate could be used as the indicators for the tolerance of tomato seedlings to low temperature and poor light.
Keywords:Tomato  Low temperature with poor light  Physiological character
