茶树芽叶的榨汁浓度是芽叶细胞液浓度的反映,在生产实践中,通常以芽叶的榨汁浓度作为判断茶树生长状况、灌溉和抗寒性的生理指标加以应用,国內外均有报导。十几年来,我们在选育茶树新品种的同时,对芽叶榨汁浓度的变化也作了一系列的观测,现归纳报导如下: 材料与方法 The juice concentration of tea leaves is a reflection of the concentration of bud cells. In the practice of production, the juice concentration of shoots is usually used as a physiological indicator to judge the growth status of tea trees, irrigation and cold hardiness. Both domestic and foreign Reported. In the past ten years, we have also made a series of observations on the changes of the juice concentration of bud leaves while breeding new varieties of tea trees. We have summarized the following reports: Materials and Methods
