Ethylene inhibitor compound 1-methylcyclopropene (1-MCP), sanitizer chlorine dioxide (ClO2) and polyhexamethylene guanidine (PHMG) were studied to know the postharvest behavior and storage life of banana fruits (cultivar Yelakki), harvested at second stage of its ripening. Banana fruits were pretreated with the above chemicals either singly or in combination and stored in corrugated fiber board boxes at ambient condition. The 1-MCP treatment had delayed the colour change of peel as well as fruit softening and extended t h e shelf life by suppressing the respiration. | Effect of chlorine dioxide polyhexa methylene guanidine and 1-methylcyclopropene on shelf life of banana Musa paradisiacal L.
