Abstract
The experiment
consisted of two popular mango varieties in Bangladesh (viz., Langra and
Khirshapat) and four different levels of Gibberellic acid (GA3)
solution, namely, control, 100, 200 and 400 ppm. The two factors experiment was
assigned in randomized complete block design with three replicates. Data obtained from various biochemical
analyses in terms of physicochemical properties and shelf life of postharvest
mango, were recorded and statistically analyzed for comparison among the mean
values using Duncan's Multiple Range Test (DMRT) and Least Significant
Difference (LSD). The Khirshapat showed better performance in achieving higher
quantity of moisture, progressively lost physiological weight, increased pulp
pH, TSS after 6th day of storage, produced more quantity of sugar
(total, reducing and non-reducing), as well as extended shelf life and delayed
skin color changes than Langra at all the storage duration. Different levels of
GA3 solution subjected to the investigation demonstrated significant
variation in most of the physicochemical properties and shelf life of mango at
different days after storage. The results explored that some physicochemical
properties viz., physiological weight
loss, moisture content, pulp pH, TSS, sugar (total, reducing and non reducing),
were rapidly increased from untreated mangoes. GA3 at 400 ppm showed
better performance in delaying the changes in physicochemical properties and extended
shelf life.
