以15年生丰后、细叶青、小青和大粒种果梅品种为试材,研究了越冬期间枝皮中几个生理指标的变化。结果表明,越冬期间,果梅枝皮含水量变化较大;可溶性糖含量先升后降,且品种间存在着显著差异;可溶性蛋白质含量在越冬初期下降,而高峰出现在越冬中期;游离脯氨酸含量表现为前期下降,中期上升到最高峰后下降,后期又升高,表现出不稳定性。 The changes of several physiological indices in the bark of 15-year-old bonsai (Fenghou), Schisandra chinensis, Xiaoqing and large-grain Prunus mume varieties were studied. The results showed that during the winter, the water content of the branch of Prunus mume significantly changed; the content of soluble sugar increased first and then decreased, and there were significant differences among the varieties; the content of soluble protein decreased in the early winter and the peak appeared in the mid-winter; The content showed a decrease in the early period, a decrease in the middle period after rising to the peak, an increase in the later period, showing instability.
