Abstract

A pot experiment was conducted to probe the effects of potassium on yield,quality, and resistance of tomato to unfavorable enviorenments. The results showed that the yield of tomato fertilized with potassium increased by 15. 71% which was more than that without K. The applying potassium promoted the absorption of N and increased the utilization ratio of N. potassium also improved the quality of tomatoes. Compared with the contrast (no - K), the content of VC of tomatoes with K increased by 13.05%, the content of reduction sugar increased by 3.95%, the content of free acide (pH) decreased by 1.83%, and the ratio of sugar acid increased by 10.68% ; But potassium had no obvious effect on total acidity of tomatoes. Application of potassium increasd the content of chlorophyll, decreased the fermeability of the cell membrane,and maintained relative stability of the cell membrane, strengthened the resistance to bad enviorenment, and decreased the accumulation of the proline. in tomato plant under the drought stress.
