摘　　要：以海南主栽杧果品种‘贵妃’为试材,在果实生育期进行萘乙酸(NAA)、爱多收(复硝酚钠)不同浓度处理的喷施试验,旨在明确2种植物生长调节剂对杧果产量和果实品质的影响。结果表明:爱多收增加产量效果较好,以高浓度的100 mg/L处理产量最高,比对照增加了102.6%,NAA低浓度可显著增加产量,高浓度则起到疏果的作用,增产效果不显著。NAA能显著促进果实膨大,爱多收则不能。在影响果皮色素方面,NAA和爱多收较低浓度(5、10 mg/L)处理延缓果皮叶绿素的降解,各处理均促进了果皮类胡萝卜素的积累,NAA较高浓度(60、100 mg/L)和爱多收5 mg/L处理抑制了果皮花青素的合成,尤其是NAA 100 mg/L,对果实采收期和完熟期的红色着色造成不利影响。NAA和爱多收对果实内在品质的影响不大。综合比较,以NAA 30 mg/L和爱多收100 mg/L处理为宜。该研究为NAA和爱多收在海南‘贵妃’杧种植中的合理应用提供了科学依据。A mango cultivar‘Guifei＇（Mangifera indica L.） was used to study the effect of naphthaleneac eticacid（NAA） and Atonik on the yield and fruit quality. The results showed that Atonik treatment had a better effect on the yield, the yield of treatment with 100 mg/L Atonik was the highest and increased 102.6% than the contrast, lower concentration of NAA could significantly increase yield, higher concentrations had the effect of thinning and could not significantly increase yield. NAA could promote fruit enlargement obvious, but Atonik could not. NAA treatment and lower concentrations of Atonik treatment（5 and 10 mg/L） delayed the degradation of mango peel＇s chlorophyll, NAA and Atonik treatments promoted accumulation of carotenoid,higher concentrations of NAA treatment（60 and 100 mg/L） inhibited synthesis of anthocyanin, NAA 100 mg/L caused adverse effects on the fruit harvest and ripening period coloring. NAA and Atonik had a little effect on the internal quality of the fruit. According to comprehensive comparison, treatments with NAA 30 mg/L and Atonik 100 mg/L were suitable. This study will provide reference for the security production of mango fruit.
