Summary

The effects of preculture on freezing resistance, sugar and water content, and the cell structure of asparagus shoot tips were examined. Freezing resistance of tips was increased by a 48 hour preculture on a medium supplmented with a high concentration of sugar. The optimal concentration of sugar in the preculture medium was 0.5 M, regardless of the sugar. It is suggested that the uptake of sugars and dehydration occurred in cells during preculture, with consequent increase of freezing resistance of precultured shoot tips.
