DORMANCY BREAKING IN JAPANESE PEARS GROWN IN A HEATED GREENHOUSE
Phenological and biochemical studies on dormancy breaking in Japanese pear were conducted; to compare the response to chilling of 'Kosui' trees growing in the normal winter climate either with or without the experience of a protected cultivation system before winter, excised shoots from the both trees were forced to break bud by approximately monthly sampling over a two year period (1991–1993). As in the experiment, it was found that the tendency for trees be more susceptible to chilling when grown under warm conditions than those grown under normal temperature conditions, as shown by the difference in periods to bud break and by the metabolism of carbohydrates, especially sugar contents, and fatty acid composition in lipid of buds and shoot.
