摘要
为明确番茄黄化曲叶病毒病(TY病毒病)与番茄叶片中各金属元素含量的关系,利用原子吸收分光光度计对不同品种及不同定植时间的番茄叶片中Mg、Ca、Fe、Mn、Cu、Zn共6种金属元素的含量进行了测定。研究结果表明:不同抗性水平的番茄品种的各金属元素含量存在显著性差异,番茄的病情指数与Mg、Mn和Zn 3种元素的含量呈线性负相关关系,且随着定植时间的增加,感病品种叶片中Mn和Zn的含量呈显著性降低。因此,在番茄生长过程中,为了抑制番茄黄化曲叶病毒病的发生,可对植株施加适量的Mn肥和Zn肥。
To clarify the relationship between tomato yellow leaf curl virus(TYLCV) and metal element contents in tomato leaves, atomic absorption spectrophotometer was used to determine the contents of Mg, Ca,Fe, Mn, Cu and Zn in leaves of different tomato varieties and different planting time. The results suggested that there were significant differences in the contents of various metal elements of tomato varieties with different resistance levels, and a negative linear correlation between the disease index and the contents of Mg, Mn and Zn. The contents of Mn and Zn in the leaves of affected varieties reduced significantly with the prolongation of planting time. Accordingly, to inhibit the development of TYLCV during tomatoes growth, appropriate amounts of Mn and Zn fertilizers could be applied to the plants.
