| Abstract: | The tomato cultivar resistant to leaf mold was screened by innoculation identification at seedling stage,the effect of the following factor on disease index was studied,the factor included seedling age of plant,concentration of innoculated fungi,temperature and time of innoculation.The optimal condition of seedlings inoculation identification for tomato leaf mold disease is as following:The 6th-true leaf seedling;The culture time of fungi for leaf mold disease is 20 days;The oncentration of inoculated fungi is 107;The temperature of cultivating yong seedlings after inoculation is 22℃. |
