1988和1989年,对座果后的椰香芒(Dashehari)叶面喷施100、200、300或400mg/L赤霉酸(GA_3),10天后再喷一次。GA_3处理使常温下(36±2℃和40±3℃)贮藏的芒果推迟6天后熟。随着GA_3浓度升高,采后芒果在前6天的后熟过程显著减慢。经200mg/L(或以上浓度)处理的芒果,采收时总可溶性固形物(TSS),TSS/酸度比、总类胡萝卜素、淀粉酶和过氧化物酶的活性均较低,总酸度、维生素C和果皮中的总叶绿素含量均显著较高。
In 1988 and 1989, 100, 200, 300 or 400 mg / L of GA3 was sprayed on the foliage of Dashehari after the fruit setting and sprayed again 10 days later. The GA_3 treatment delayed the storage of mango stored at room temperature (36 ± 2 ℃ and 40 ± 3 ℃) for 6 days. With the GA 3 concentration increased, postharvest mango significantly slowed down after the first 6 days of ripening. Mangosters treated at 200 mg / L (or above) had lower total soluble solids (TSS), TSS / acid ratio, total carotenoids, amylase and peroxidase activity at harvest and lower total acidity, Total chlorophyll content in vitamin C and peel was significantly higher.
