摘　　要：以温敏型雄性不育系T-4及保持系First为试材,通过观察花粉发芽情况、统计果实种子数、观察花器官,并测定花药内脯氨酸、淀粉及可溶性糖含量,探究不同温度处理条件下,番茄生殖生长期不育系与保持系生理生化特性差异。结果表明:T-4在昼28℃/夜18℃的可育温度条件下花粉发芽率、果实种子数、脯氨酸、淀粉及可溶性糖含量均高于昼28℃/夜24℃及昼28℃/夜12℃的不育温度条件下的处理;与保持系First不存在显著差异。Take thermo-sensitive male sterile tomato line ＇T-4＇ and maintainer line ＇First＇as the material,and researches on physiological and biochemical properties of male-sterile line and maintainer under different temperature,by observing pollen germination,floral organ,counting seeds number,and measuring the contents of proline,starch,as well as soluble sugar respectively in anthers during the reproductive stage were conducted.The results showed that pollen germination,seeds number,the proline,starch and soluble sugar content of ＇T-4＇in fertile conditions（at day 28℃/night 18℃）were respectively significantly higher than those which were in sterile conditions（at day 28℃/night 24℃ and day 28℃/night 12℃）.There were no significant differences between ＇T-4＇and maintainer line ＇First＇.
