Résumé

Heat shock applied before chilling has previously been shown to increase the chilling tolerance of cucumber and rice seedlings and of tomato fruit. The subsequent rate of radicle growth after chilling of these seedlings is a sensitive measure of chilling injury as is the subsequent increase in ion leakage from chilled discs of tomato pericarp fruit tissue. The data presented show that a brief heat-shock applied after chilling decreases the subsequent development of chilling injury symptoms in cucumber and rice seedlings and in tomato pericarp discs. This induced effect is optimal if applied 1 h after removal from chilling.
