摘　　要：研究了不同光周期(L24D0、L14D10和L9D15)对西葫芦幼苗生长状况、根系活力和可溶性蛋白含量的影响。结果表明:西葫芦幼苗叶面积、茎粗、生长速率、根冠比、壮苗指数、根系活力和叶片可溶性蛋白含量都是24 h光照处理的最高,其次是15 h光照处理,9 h光照处理最低。长日照促进西葫芦幼苗生长,提高根系活力和叶片可溶性蛋白含量。The effect of different photoperiod（DOL24,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.
