以台农1号芒果为试验对象,研究CPPU对芒果的壮果效果及吲熟酯对芒果的疏果效应。结果表明,花后7 d及花后21 d各喷施1次32 mg/L CPPU,芒果的果实大小显著提高,对果实品质和风味影响不明显;花后7 d喷施1次200 mg/L吲熟酯,能明显提高芒果的落果率和单果质量,果实等级规格提高,可溶性固形物含量增加并达到最大值,疏果效果较好。 The effect of CPPU on the mango fruit and the thinning effect of indole ester on the mango fruit were studied in the experiment. The results showed that on the 7th day after anthesis and on the 21st day after anthesis, 32 mg / L CPPU was sprayed once, the fruit size of mango was significantly increased and the effect on fruit quality and flavor was insignificant. On the 7th day after anthesis, L indolesterol can obviously improve the fruit drop rate and fruit quality of mango. The grade of fruit grade increased, the content of soluble solid content increased and reached the maximum value, and the fruit thinning effect was better.
