Effects of different storage humidity on the quality of vegetable seedlings

The effect of different store and transport humidity (50%, 70%, 90%) on the main quality index of tomato seedlings during store and transport was studied. The results showed that activity of root system decreased by 87.68%, 68.93% and 72.93% respectively; Chlorophyll content decreased by 69.39%, 58.71% and 66.65% respectively on the 9th day. The decrease of activity of root system and chlorophyll content in 70% humidity were relatively little, and after field planting, heart leave grew faster, seedlings quality was the better.
