摘　　要：[目的]研究果实发育前期喷施低浓度乙烯利对菠萝[Ananas comosus(L.)Merr.]果实生长发育和品质的影响。[方法]每株叶面喷施40μg/L乙烯利溶液,测量菠萝果实的单果重、横径、纵径、可溶性固形物含量、VC含量、可溶性糖含量、有机酸含量。[结果]在花后喷施40μg/L乙烯利溶液,对果实的纵径、横径、单果重、可溶性糖含量、可溶性固形物含量都有不同程度的促进作用,对可滴定酸含量有不同程度的降低作用。[结论]该研究可为科学合理地使用乙烯提供指导。[ Objective ] The aim was to study the effeets of applying ethephon in early fruit development on fruit growth and development and quality of pineapple. [ Method] Every pineapple plant was sprayed 40 μg/L ethephon on the leaf, and then determined its single fruit weight, fruit＇s transverse diameter and vertical diameter, soluble solids content, Vc eontent, soluble sugar content, and organic acids content. [ Result] 40 μg/L ethephon liquid applying after flowering on the leaf had a promoting effeet on fruit＇ s transverse diameter and vertieal diameter, single fruit weight, soluble sugar content, and soluble solids content in a degree, while had opposite effect on titratable acidity eontent. [ Conclusion] The study provides a reference for the scientific applieation of ethephon.
