摘　　要：测定了弱光条件下番茄幼苗的根、茎、叶干物质重量的变化,从中得出不同弱光条件及处理时间长短对番茄幼苗生长的影响。结果表明,处理时间越长,光照越弱,对番茄幼苗生长的影响越明显;不同的番茄品种之间对弱光反应存在较大差异,培育耐弱光的番茄品种是切实可行的。The varieties of tomato were used to study the effect of weaklight on plant growth in seedling stage.The results indicated that two light levels and different stages are affect on the growth of plant.And the changes were obvious different among varieties in the weaklight condition,the effect is according to the time of tolerance.It was possible to find varieties fitting for weaklight.
