Abstract:: To solve the problem encountered in Xinjiang Turpan melon factory nursery proccess that were easy to produce leggy seedling and difficult to cultivate strong seedling，‘XiZhou Mi 17’ melon was selected as test material，different concentration of plant growth retardant multi-effect PP333 and B9 on the influence of melon seedling quality was studied.The results showed that，the seedling germination potential decreased with the increase of concentration of PP333 solution；plant height and hypocotyl length of seedling was significantly less than control；under the concentration of 60 mg/L PP333 solution，seedling blade thickness and seedling index reached the maximum；under the concentration of 60 mg/L and 80 mg/L，seedling root cap was the maximun.Inhibitory effect of PP333 seed solution was strong than B9 solution at seedling height，hypocotyl length，petiole length，leaf size and thickness of inhibitory effect than B9 solution.
