Abstract

The effect of different photoperiod(D0L24,D10L14,D15L9) on growth,root activity and soluble protein content of summer squash seedling were studied.The results showed that: the growth rate,stem diameter,R/T,seedling index,and soluble protein content of summer squash seedling were the highest when the light time was 24 h,next was 15 h,and they were the lowest when the light time was 9 h.The summer squash seedling growth can be promoted,root activity and the soluble protein content in leaves increased when extend the illumination time.
