本试验结果表明：苗期光照度对番茄畸形果发生有显著的影响。遮光度为３２％就可显著地降低畸形果的发生率和发生程度，尤其是降低乱形果中混发果的发生率和发生程度。随着遮光度的增加，降低畸形果发生的作用就更大，但遮光对畸形果发生类型及椭圆果的发生率无显著影响。低温会削弱遮光对番茄畸形果发生率的降低作用和发生程度的减轻作用。因此，番茄在低温期育苗，适当减弱光照度也会减轻畸形果的发生
The results showed that: seedling light intensity on tomato malformations have a significant impact. Shading degree of 32% can significantly reduce the incidence of deformities and the degree of occurrence, in particular, reduce the incidence of confused fruit jamming and the occurrence of degree. With the increase of shading degree, the effect of reducing the occurrence of deformity is greater, but shading has no significant effect on the type of deformity and the incidence of oval fruit. Low temperature will weaken the effect of shading on the reduction and occurrence of tomato deformity. Therefore, tomato nursery seedlings at low temperatures, appropriately reduce the light intensity will reduce the occurrence of deformed fruit
