用10 mg·l - 1的NAA和5、10、15 mg·l - 1的二氯丙分别处理5个苹果品种，为期2年。虽然不同品种的反应不同，但与对照相比，NAA普遍延迟果实脱落。5 mg·l - 1的二氯丙通常比NAA更有效地降低采前滴落。“Stayman”、“Rome Beauty”和“Winesap”的采收前滴度与二氯丙浓度呈负相关，但“Delicious”没有。果实的红度、果肉硬度、可溶性固形物含量和淀粉等级在收获或储存期间没有受到任何处理的一致影响。二氯丙在果实中的残留量与处理浓度有关，并持续到收获。化学名称：萘乙酸（NAA）；2-（2,4-二氯苯氧基）丙酸（二氯丙）。
Five apple (Malus domestica) cultivars were treated with NAA at 10 mg·liter–1 and dichlorprop at 5, 10, and 15 mg·liter–1 during 2 years. Although the response varied with cultivar, NAA generally delayed fruit abscission compared to the control. Preharvest drop was usually reduced by dichlorprop at 5 mg·liter–1 more effectively than by NAA. Preharvest drop of ‘Stayman’, ‘Rome Beauty’, and ‘Winesap’, but not ‘Delicious’, was inversely related to concentration of dichlorprop. Fruit redness, flesh firmness, soluble solids content, and starch ratings were not affected consistently at harvest or during storage by any treatment for any cultivar. Residue levels of dichlorprop in the fruit were related to treatment concentration and persisted until harvest. Chemical names used: naphthalene acetic acid (NAA); 2-(2,4-dichlorophenoxy) propanoic acid (dichlorprop).
