通过多种途径和方法，进行番茄耐低温和耐弱光性能鉴定，结果表明，苗期受低温伤害程度（冷害），结合低温处理后叶片电导值增加量、细胞膜伤害率测定和弱光下的相对座果率、相对产量，可作为番茄耐低温、耐弱光性能的鉴定指标。
Through a variety of ways and methods, the identification of low temperature tolerance and low light tolerance of tomato was carried out. The results showed that low temperature damage (cold injury) at seedling stage, combined with the increase of leaf conductance value after low temperature treatment, Relative fruit rate, relative yield, can be used as tomato low temperature, resistance to weak light performance identification index.
