The study was conducted in mango to understand the relationship of various metabolites with flower sex ratio (hermaphrodite/male) and fruit set using stem girdling technique. Girdling one year old branches was carried out in two cultivars, Mangifera indica 'Alphonso' and 'Totapuri' to retain 50, 100 and 150 leaves to vary the content of hormones, sugars, and amino acids. The increased leaf number was found to increase the total sugars, glucose, fructose, and other sugars. Girdling also significantly increased the concentration of abscisic acid (ABA), salicylic acid (SA), jasmonic acid (JA), indole acetic acid, indole butyric acid but decreased gibberellins and cytokinins. Amino acids also increased in the girdled branches. Girdling improved the flower sex ratio as well as fruit set more efficiently in 'Alphonso' than in 'Totapuri'. Results indicate that the increase in production of hermaphrodite flowers may be more related to the higher production of growth inhibitors, like ABA, SA, and JA along with increased concentration of sugars. Increased auxin concentration also might play an important role in increasing the fruit set.

“…Khandakar (2011) performed girdling technique on wax jamun fruits and concluded that chlorophyll content, yield, fruit size as well as faster fruit growth increases in wax jamun due to girdling. More seed-pulp ratios in litchi have been found in the case of the girdling x 40 DAfS x leaf elimination, which is in line with Singh et al, (2006), and Das et al, (2006). Rufato (2015) performed girdling on European pear variety "packham"s Triumph" grafting on pyruscalleryana root stock and reported that due to girdling yield of pear increases.…”

The objectives of this investigation are to study nitrogen uptake, translocation, accumulation and distribution in mango tree organs using labeled nitrogen (15N) and to understand the mechanism of boron action in increasing fruit yield in the off-year. A field experiment was conducted using fifteen-year-old mango trees (cv. Zebda) grown at Al Malak Valley Farm, El-Sharkeya Governorate-Egypt. Treatments included the application of (15NH4)2SO4, “in the on-year”, at a rate of 50 g nitrogen/tree through the stem injection technique. While boron was sprayed on the same trees “in the off-year” at the following rates: 0.0 (control), 250 and 500 mg·L–1. The authors hypothesize that boron and nitrogen act synergistically to increase mango fruit yield in the off-year. Results indicated that the highest 15N uptake and accumulation in the on and off-years was observed in the upper (young leaves). When boron was applied at 250 mg·L–1, in the off-year, the upper (young leaves) recorded the highest 15N uptake and accumulation (%15Ndff = 13.93) relative to the other two leaf categories and those of the on-year. In the on-year fruit accumulated higher 15N than leaf or bud. In the off-year, bud exhibited the highest 15N accumulation without boron application, while leaves exhibited the highest 15N with boron application. The highest %15Ndff in all tree organs was observed at 250 mg·L–1 boron rate. Boron increased nitrogen uptake, translocation and accumulation in mango tree organs. A synergistic relationship was observed between boron and nitrogen which led to an increase in fruit yield in the off-year.
