土壤施钾可增加胶树胶乳产量。本文试图以产胶生理为重点去揭示这一现象。蔗糖是胶乳的糖原,它的酵解由转化酶控制。因此,乳管蔗糖含量的多少和转化酶活性,是决定胶树生产潜力的两个重要因素。钾可激活酶的活性,在PH值高的条件下其活性更高。已经知道,钾对蔗糖运输有肯定的影响。我们利用同位素示踪技术,研究钾对其他矿物营养元素流动的影响,特别是钙在韧皮部是相对不流动的,它对生物膜和组织的稳定性起着重要作用。当钙施于树皮割口时,它进入树皮向乳管的移动是通过离子交换场所,并随钾数量的增加而移动率加快。与乳清相比,尽管黄色体部分的天然钙浓度很高,但大部分外用钙都累积在黄色体中。 细胞质可容纳钙的上限量受有机酸组分的控制。胶树施用刺激剂后发现乳清中的钙浓度和pH值有变化。因此,通过对胶乳,特别是细胞质乳清的研究,可以预测种植在不同农业气候条件下胶树的产胶潜力、适宜的割胶制度和褐皮病的发病率。
Soil potassium can increase gum rubber latex production. This article attempts to reveal the phenomenon of rubber production physiology. Sucrose is the glycogen of latex and its digestion is controlled by the invertase. Therefore, the amount of sucrose in the milk tube and the activity of invertase are two important factors that determine the production potential of gum trees. Potassium activates enzyme activity and is more active at high pH. It is already known that potassium has a positive effect on sucrose transport. We use isotope tracing techniques to study the effects of potassium on the flux of other mineral nutrients, especially calcium, which is relatively non-mobile in the phloem and plays an important role in biofilm and tissue stability. When calcium is applied to the bark cut, it moves through the bark to the tube through the ion exchange site and moves faster as the amount of potassium increases. Compared with whey, although the yellow body part of the natural calcium concentration is high, but most of the topical calcium accumulation in the yellow body. The maximum amount of cytoplasm that can hold calcium is controlled by the organic acid component. Changes in calcium concentration and pH in whey were observed after the gum tree was stimulated. Therefore, through the study of latex, especially cytoplasmic whey, it is possible to predict the plasticizing potential of gum trees planting under different agro-climatic conditions, the appropriate tapping system and the incidence of brown skin disease.
