| 摘 要： | 本文以不同抗寒力的巴西橡胶实生母树、无性系幼树和幼苗等为对象,比较研究它们在越冬期间的生理特性差异。研究结果表明,抗寒性强的橡胶实生母树、无性系幼树和幼苗的枝条和叶片,通常比抗寒性弱者具有较弱的呼吸强度、较低量的水分和还原糖,而含较高量的淀粉、蛋白氮,以及叶片含有较多的束缚水和蔗糖。

STUDIES ON THE PHYSIOLOGICAL CHARACTERS OF DIFFERENT COLD-RESISTANCE OF HEVEA BRASILIENSIS |
| |
| Abstract: | The physiological characters of different cold-resistance rubber clone younglings and rubber seedling plants were investigated in winter. The results were obtained as follows; the sprigs and leaves of the cold-resistant rubber clone younglings and the cold-resistant rubber seedling plants generally had weaker respiration, lower water content and reducing sugar content, higher starch content and protein-N content than non-resistaat. In addition, the former had more sucrose content and bound water content in the leaves than the later. |
