| Abstract: | The result of the application of 10,5,2.5,1.25,0.625 g/L of "Lengdongbao" with different concentrations in tomato seedling under low temperature stress showed that "Lengdongbao" not only raised the content of the soluble sugar and pro, but also increased the activity of protective enzyme. At the same time, electrolytic leakage decreased and the contents of chlorophyll was increased. The treated tomato showed high chill-resistance with better comprehensive appreciation and the best concentration was 2.5～1.25g/L. |
