Abstract: 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.
