摘　　要：以雪花梨为试材,研究了4种生长调节剂对梨果实生长发育的调控效应。结果表明,F1和C14既促进了果实膨大,又提高了果肉可溶性糖含量和糖/酸比值或Vc含量,而且二者均未引起果肉硬度与可溶性固形物含量的降低;F4对果实大小以及可溶性糖、可溶性固形物和可滴定酸含量无显著影响,但显著增加了果肉硬度和Vc含量。<Abstrcat> Effects of 4 growth regulators on fruit development in pear (Pyrus bretschneideri Rehd.cv.xuahua) were studied. The results showed that F1 and C14 promoted fruit expansion ,and advanced flesh soluble sugar content and ratio of sugar and acid or Vitamin C content.Moreover,Neither of them lead to (decrease) of flesh firmness and soluble solid content. F4 didn't significantly effect fruit size,soluble sugar,titratable acid and soluble solid content,however, significantly increased flesh firmness and Vitamin C content..
