观察巴西橡胶树胶乳产量在一日之间的变异和在季节之间的变异,并不能说明排胶现象的特性。产量的波动可能与下列两种现象有关:①随一天之内不同时间和不同季节而变异的植株内的胶乳贮备量;②排胶特性的变异。对排胶现象的系统研究,证明了另一个假设,即在割胶后排胶困难是产量的限制因子。
It is not clear from the observation that the rubber tree latex production variation between one day and the variation between seasons does not explain the phenomenon of the rubber discharge phenomenon. Fluctuations in production may be related to the following two phenomena: (i) stock of latex in plants that varies with time and season at different times of the day; (ii) variability of discharge characteristics. A systematic study of the phenomenon of plastic discharge proved another hypothesis that the difficulty of plasticizing after tapping is the limiting factor of production.
