在芒果《Mangifera indica L》栽培品种Dusehri的芽膨胀后期,分别用0、500、1000、2000、3000、4000、5000PPm的硼酸进行叶面喷施.结果和对照然相比,显著地增加了果树的营养生长、花穗的长和宽、保果率、总的可溶性固形物(TSS)、TSS/酸比值和果实的总糖含量.硼酸浓度超过3000PPm则表现了抑制两性花百分率的效果.施用浓度大于4000PPm时,则减少了果实的长度、宽度和重量以及内/核比例.所有各处理的果实抗坏血酸含量都显著低于对照.施用3000PPm的硼酸可以获得大多数满意的结果.
Foliar application of boric acid at 0, 500, 1000, 2000, 3000, 4000, and 5000 ppm, respectively, in the late stage of bud swelling of mango “Mangifera indica L” cultivar Dusehri resulted in a significant increase in fruit trees (TSS), TSS / acid ratio and the total sugar content of the fruit.When the concentration of boric acid exceeds 3000PPm, the effect of inhibiting the percentage of bisexual flower is shown. At concentrations greater than 4000 ppm, the fruit length, width and weight, and internal / nuclear ratio were reduced.The fruit ascorbic acid content was significantly lower for all treatments than for the control.Applying 3000 ppm boric acid yielded most of the satisfactory results.
