Abstract

The 2500 ppm MH “toothpick” treatment had the highest weight of sound bulbs in both cold and common storage, though it was not statistically significant. Rotting was significantly more in common storage than in cold storage. MH treated bulbs rotted more readily than the untreated bulbs in common storage. In general, sprouting was less in common storage, but almost all the buls were rotten.

The stimulating effect of MH among sprouted bulbs was observed during the first week in common storage. Dipping sprouted bulbs for about one hour in 4000 ppm MH had the shortest sprout after the third week and third month in common and cold storage, respectively. MH treated bulbs had shorter sprouts than the check in both storages at the end of the experiment.

Onion bulbs withdrawn from cold storage and placed in common storage had less number of rotten bulbs than those kept in common storage prior to the experiment. The number of sprouted bulbs in the former was eight times that of the latter.
