Abstract:
The present investigation was conducted at the Instructional Farm, Department of Horticulture, College of Agriculture, Ummedganj, Kota during October, 2020 to March, 2021. The experiment was consisting of 16 treatment combinations with two factors i.e. GA₃ with four levels (0, 25, 50 and 75 ppm) and boron with four levels (0, 0.2, 0.4 and 0.6 per cent) was laid out in Factorial Randomized Block design with three replications. After harvesting, fruits were kept in brown paper bag and stored at ambient room temperature and relative humidity. The treated fruits were analyzed for (PLW) physiological loss weight the minimum (16.67%) during storage was recorded with T₁₅ (GA₃ @75 ppm + B @0.6%), which was statistically at par with treatment T₁₀ (GA₃ @50 ppm + B @0.4%) and T₁₄ (GA₃ @75 ppm + B @0.4%) against the maximum (26.17%) physiological loss in weight under control. Rotting (%) at 0, 3rd, 6th and 9th day of storage among the various treatments, the minimum percentage of rotting (67.80%) was recorded with T₁₀ (GA₃ @50 ppm + B @0.4%) which was statistically at par with treatment T₁₁ (GA₃ @50 ppm + B @0.6%) at the end of storage period against the maximum (79.23%) under control. During storage maximum reduction in dry matter content (28.47%) observed in T₁₅ (GA₃ @75 ppm + B @0.6%), which was statistically at par with treatment T₁₀ (GA₃ @50 ppm + B @0.4%) and minimum in T₀ (control) and storage period ascorbic acid content of ber fruits (92.33 mg) was recorded maximum with treatment T₁₁ (GA₃ @50 ppm + B @0.6%), which was statistically at par with treatment T₁₅ (GA₃ @75 ppm + B @0.6%) and T₁₀ (GA₃ @50 ppm + B @0.4%) minimum in T₀ (control). It may therefore, be recommended that the pre-harvesting application of (GA₃ @50 ppm + B @0.4%) is statistically improve the storage life and quality at ambient room temperature.
