用四株12龄的橡胶树PR107无性系定量地研究了抽生第一蓬叶时,新植物体的日平均生长和体内贮藏性物质的消耗和再生规律。发现树冠叶蓬的干物质增长以变色至稳定期最快,而体内的贮藏性物质也以此时消耗最多。叶蓬稳定后,便开始了非同化器官的生长和新鲜淀粉等的贮藏。不同器官和组织在消耗和集存贮藏性物质的速度和数量上是有差异的。以枝条中贮藏性物质的消耗速度最快,次为茎干,最次为根部;而重新积累的速度恰恰相反,先根系而后茎干和枝条。因此,在叶莲老化后14天,根部的干物重可恢复到萌动时的水平,淀粉贮量亦可恢复到原有贮量的83％;而茎干和枝条的干物重则只能分别恢复到原有重量的90％(茎干)和44％(枝条),淀粉贮量的恢复速度更慢,仅分别相当于原有贮量的74％(茎干)和23％(枝条)。根据贮藏物质转换效率的实测值,估算了形成新植物体所消耗的贮藏物质总量,得到了其总消耗量中约1/3来自原有贮藏性物质,2/3来自叶片本身的光合作用的有趣结果。 Four clones of 12-year-old rubber tree PR107 clones were used to quantitatively study the daily average growth of new plants and the consumption and regeneration of in vivo storage materials when the first leaf was sprinkled. It was found that the dry matter of C. canopy increased to change color to the fastest, while the storage material in the body consumed the most at this time. Ye Peng stability, they began to non-assimilate organ growth and storage of fresh starch and so on. Different organs and tissues differ in the speed and quantity of stored matter stored and stored. To the branches of the fastest consumption of stored substances, times for the stem, the most for the root; and the speed of re-accumulation on the contrary, the first roots and stems and branches. Therefore, 14 days after the leaf lotus leaf was aged, the dry matter weight at the roots recovered to the level at the time of germination, and the starch storage capacity could be restored to 83% of the original storage amount. However, the dry matter weights of the stems and shoots could only be restored Starch stocks recovered more slowly at 90% (stems) and 44% (branches) of the original weight, at 74% (stems) and 23% (branches) of the original stock, respectively. According to the measured values ​​of the storage material conversion efficiency, the total amount of storage material consumed in the formation of a new plant was estimated, and about 1/3 of the total storage material was obtained from the original storage material, and about two-thirds came from the photosynthesis of the leaf itself Interesting result.
