摘要
Abstract
The freezing resistance of three Diospyros species and seventeen cultivars of D.kaki was evaluated by the differential thermal analysis (DTA) and electrolyte leakage from the tissues after freezing treatments. The results showed that the difference of freezing resistance between the three Diospyros' was significant, but there was no significant differnce among the kaki cultivars. The hardiest species during the coldest period of the season was D.lotus(♂ was -29.1℃, ♀ was-28.6℃)followed by D.kaki (-21.0～-27.0℃)，and the least hardy was D.taitoensis(-16.5℃)which is distributed in subtropical Taiwan. The rate of temperature decreasing significantly affected the trees' freezing resistance. The duration to attain some low injury temperature was shown to be of significance: the resalts showed that, the more the duration was long, the more the trees suffered from freezing injury. To some degree, cold acclimation could increase the freezing resistanes of kaki cultivars. No relationship was found between freezing resistance and sweet or astringent cultivars of Japanese persimmons.关键词
