Postharvest application of salicylic acid to onion bulbs for sprout inhibition.

Salicylic acid was applied to a red-skinned variety of onion bulbs in at 200, 400, 600, 800 or 1000 ppm by dipping. The bulbs were stored along with a control treatment for 4 months under ambient conditions of 35 deg C, with 70% RH. Significant loss of moisture occurred in all the treated and untreated bulbs during storage; this was highest in the control and lowest in bulbs treated with 1000 ppm salicylic acid. It was observed that sprouting started after storage for 4 weeks in the controls and increased consistently during storage. The samples treated with 600, 800 or 1000 ppm salicylic acid showed some sprouting but it was delayed as compared to control and other treatments. Rotting increased during storage in all the treatments, but it was highest in untreated bulbs, intermediate in onions treated with salicylic acid at 200 or 400 ppm and lowest in onions treated with 600, 800 or 1000 ppm salicylic acid. Overall acceptability scores were highest in bulbs treated with 600, 800 or 1000 ppm sal

icylic acid. Bulbs in the control treatment were not liked by the panel judges due to softness and heavy sprouting.
