利用新研制的植物调节剂———果利达 (GLD)在芒果上进行了初步应用研究 ,结果表明 :( 1 )GLD能促进芒果座果 ,其中GLD3# 、GLD5# 效果较好 ,应用GLD3# 、GLD5# 药剂2 0、1 0、5mg/L ,座果率分别比对照提高 1 1 .5%、2 9.7%、2 6 .6 %和 8.6 %、1 6 .2 %、2 4 .7% ;( 2 )GLD能够拉长果径 ,促进果实增大 ,提高芒果的平均单果重 ,紫花芒果平均单果重比对照提高 6 .2 2 %以上 ,桂香芒果提高 1 3.6 %以上 ;( 3)GLD可以提高果实的硬度 ,使果实后熟期延长 ,更耐贮存 ,果实的可溶性固形物百分含量与对照相比持平或稍降低 ;( 4 )果利达对芒果的营养生长具有一定的促进作用
The results showed that: (1) GLD can promote the fruit of the mango, including GLD3 #, GLD5 # effect is better, the application of GLD3 #, GLD5 # 2, 10, 05 mg / L, and fruit set rate increased by 11.5%, 27.7%, 26.6% and 8.6%, 16.2% and 24%, respectively. 7%; (2) GLD could elongate the fruit diameter, promote the fruit enlargement, and increase the average fruit weight of mango. The average fruit weight of Vitex mango was over 6.22% higher than that of the control, while the cinnamon mango increased by 13.6% ) GLD can increase the hardness of fruit, prolong the ripening period of fruit, more resistant to storage, the percentage of soluble solids in fruit is flat or slightly lower than that of the control; (4) Fruit Leader has a certain effect on the vegetative growth of mango enhancement
