[Objective] The aim was to study the effects 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 content,soluble sugar content,and organic acids content.[Result]40 μg/L ethephon liquid applying after flowering on the leaf had a promoting effect on fruit' s transverse diameter and vertical diameter,single fruit weight,soluble sugar content,and soluble solids content in a degree,while had opposite effect on titratable acidity content.[Conclusion]The study provides a reference for the scientific application of ethephon.%[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40 μg/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.
