An attempt has been made to treat sensation mango fruits with 10 mmol X L-1 boric acid with the aim to see whether boric acid has some effect on delaying ripening process, especially those ripening associated changes. Results obtained during an 8-day ripening period have shown that (1) in boric acid treatment fruits didn't lose fresh weight so drastically as in control, so did the chlorophyll content in the skin, (2) boric acid treated fruits were higher in activity of pectin methyl esterase (PME) and polygalacturonase (PG) than control with PME peak coming 2 days earlier than that of PG and (3) boric acid lowered respiratory activity of the fruit as compared to control with no effect on total sugar content in the pulp
