摘要:: 以6叶1心期“金棚一号”番茄幼苗为试材，研究了外源喷施1400mg/L CaCl²对低温逆境下番茄幼苗相对电导率、丙二醛含量、开花期、花粉活力、坐果率、单果重及单穗果产量的影响。结果表明：低温逆境下，外源喷施CaCl²在调控番茄开花结果中发挥着重要作用。与低温对照相比，在低温处理的第6、9天，低温前或低温后喷钙均降低了番茄幼苗的相对电导率及丙二醛含量，低温前喷钙处理显著提高了番茄第1穗花花粉活力（P<0.05），低温前或低温后喷钙处理，使番茄第1穗花开花期提前2d，显著提高了第1穗果坐果率及产量（P<0.05）。

Abstract:: With ‘Jinpeng No.1’ tomato with six true leaves as materials,the effect of exogenous CaCl² which concentration was 1 400 mg/L on the relative electric conductivity,content of MDA,flowering stage,pollen vitality,fruit setting rate,single fruit weight and single panicle yield of tomato under cold stress were studied.The results showed that the exogenous calcium played an important role in blossom and yield of tomato under cold stress.Compared with the low temperature control,the relative electric conductivity and MDA content of the two groups which treated with spraying CaCl² were significantly reduced (P<0.05).The flowering stage in the first inflorescence of the two groups treated with spraying CaCl² was 2 days earlier than the low temperature control.And the pollen vitality in the first inflorescence of the group treated with spraying CaCl² before the low temperature treatment was significantly higher than the low temperature control(P<0.05).Compared with the low temperature control,the fruit setting rate and the tomato yield in the first inflorescence of the two groups which treated with spraying CaCl²significantly increased (P<0.05).
