摘　　要：为解决新疆吐鲁番地区甜瓜工厂化育苗当中遇到的容易出现徒长苗,不易培育出适龄壮苗等问题,选用甜瓜品种"西州密十七号"为试材,研究不同浓度植物生长延缓剂多效唑(PP333)和比久(B9)浸种处理对甜瓜幼苗质量的影响。结果表明:甜瓜幼苗发芽势随着PP333溶液浓度的增大而降低,幼苗的株高和下胚轴长显著小于对照;浓度为60mg/L的PP333溶液浸种处理下的幼苗叶片厚度和幼苗壮苗指数最大;60mg/L和80mg/L的PP333溶液浸种处理下幼苗根冠比最大。PP333溶液浸种处理对甜瓜幼苗的株高、下胚轴长、叶片大小和厚度的抑制作用大于B9溶液,可以用于防止幼苗徒长,培育壮苗。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 B9on the influence of melon seedling quality was studied.The results showed that,the seedling germination potential decreased with the increase of concentration of PP333solution;plant height and hypocotyl length of seedling was significantly less than control;under the concentration of 60mg/L PP333 solution,seedling blade thickness and seedling index reached the maximum;under the concentration of 60mg/L and80mg/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.
