“…Foliar spray of GA 3 might also have affected the physiological processes resulting into higher production of mango. These results are in conformity with the finding of Bezerra et al [17], Nkansh [18] and Ghosh [19] and Dheeraj et al [20] in mango.…”

An experiment on “Effect of Plant growth regulators on fruit yield and fruit quality of Mango (Mangifera indica L.) cv. Amrapali” was conducted at the research plot, College of Horticulture, Chiplima during the year 2020-21 by using Randomized Block Design with three replications and ten treatments. Three concentrations of NAA i.e. 10, 20 and 30 ppm, three concentrations of GA3 i.e. 10, 20 and 30 ppm and three concentrations of 2,4-D i.e. 10, 20 and 30 ppm were applied at pea and marble stage of fruit. Research work was held on 07 years old plants of mango cv. Amrapali. Highest fruit weight (263.21g), and total yield of 18.34 kg per plant were recorded under T7. The minimum yield (4.41 kg per plant) was recorded under T1 (Control). The highest number of fruits per plant(69.67) and fruit yield (18.34 kg per plant ) was recorded under treatment T7 (30 ppm foliar application of GA3). The maximum TSS: acid ratio (115.81) was obtained with T10 (30 ppm concentration of 2,4-D) which was known to be superior from all other treatments. The minimum TSS: acid ratio (55.00) was estimated under T1. Ascorbic acid content of mango cv. Amrapali ranged from 39.34 mg/100g (T10) to 55.97 mg/100g (T1). The highest total sugar content (14.99 %) was estimated in T10 (2,4-D at 20 ppm) while the lowest total sugar content (10.42 %) was estimated in T1 (Control). T10 (30 ppm foliar applications of 2,4-D) showed maximum ascorbic acid content (55.97 mg/100g), while lowest (39.34 mg/100 g) was recorded under T1 (Control). It is concluded that the foliar application of 30 ppm GA3 (Gibberellic acid) and 30 ppm 2,4-D were found to be optimum concentrations which showed best results by increasing yield and fruit quality of mango cv. Amrapali.

Could an Early Treatment with GA and BA Impact Prolonged Cold Storage and Shelf Life of Apricot?

Application of plant growth regulators (PGRs) in apricot orchards is a common practice with a goal of improving yield and/or quality of fruits at harvest. However, the question of whether such treatment alters postharvest properties is seldom answered. The effects of an early application of PGRs on postharvest changes on apricots were investigated on cultivar NS-4, grown on Myrobalan rootstock with blackthorn interstock in a 5-year-old orchard. PGR treatments included 50 and 100 ppm of benzyladenine (BA) and 200 ppm of gibberellic acid (GA3), which were applied when the green ovary was surrounded by dying a sepal crown, at the stage where sepals beginning to fall. Apricots at the stage of commercial ripeness were used for the postharvest experiments. Analysis was performed at harvest, after 21 days of cold storage (at 1 ± 1 °C and 80 ± 10% RH), and after 3 days of shelf life (24 ± 2 °C). At harvest, significant differences were observed between treated and untreated fruits regarding flesh firmness, color, ethylene production and respiration rate, flavonoid, carotenoid and citric acid content, while application of BA100 changed TA and TSS. Prolonged cold storage reduced the initial differences in firmness, respiration rate, flavonoid and carotenoid contents, but new differences in fructose, malic and succinic acid contents began to appear. Shelf life reduced the difference in citric acid, but differences in TA, TSS, phenol and flavonoid content appeared. There is no difference in the sensory properties of treated and non-treated fruit after cold storage and shelf life.
