| 摘 要： | 试验表明番茄苗期低夜温不仅提高了畸形果发生率，而且也提高了畸形果平均级数和综合指数，并增加了畸形果的类型，同时乱形果在畸形果中所占的比例也增大。试验还认为：引起番茄畸形果大量发生的界限温度在大于６℃和小于１２℃的范围内，低温所需时间为幼苗２片子叶充分展开后１０～１６天，幼苗低温敏感期为２～４片真叶展开期。因此，番茄育苗期间应避免２～４片真叶展开期夜温低于１２℃。

| Abstract: | The results indicated that low night temperature in tomato seedling stage increased incidence,average grade and intergated index of malformed fruit,as well as the types of them. It was found that the critical temperature which induced high incidence of malformed fruit was between 6～12℃,the 10th～16th days after the two cotyledons fully expanded. The susceptible period for low temperature was at the stage of the 2nd～4th true leaves fully expanded. Therefore,tomato seedlings with 2～4 true leaves must be kept a... |
