割胶的一种影响看来是使乳管壁的性质发生变化,以致溶质的进入受到限制和胶乳的溶质浓穹大大降低。提高割胶强度时,这种反应就更为显著,可以说胶树死皮的原因是由于被酶作用物的临界缺乏和胶乳最后就地凝固。增加割胶强度必然增加乳管对浸渍剂的抗力(浸渍剂用25N硫酸、纤维素酶、冷的氯化钾硝酸溶液和次氯酸盐溶液轮流浸提)。未割胶的正常组织差不多能完全溶解,然而,褐皮病的皮层组织却产生大量完全孤立的乳管碎片残留物。这种残留物保持它的正常的联接型式,它不能粘
One effect of tapping appears to be to alter the properties of the tube wall so that solute entry is limited and the solute vault of the latex is greatly reduced. Improve the tapping strength, the reaction is even more pronounced, we can say that the reason for dead skin gum is due to the critical lack of enzyme substrate and latex in situ solidification. Increasing the tapping strength inevitably increases the resistance of the mains to the impregnating agent (the impregnating agent is alternately leached with 25 N sulfuric acid, cellulase, cold potassium chloride nitric acid solution and hypochlorite solution). The normal tissue that is not tapping is almost completely dissolved, however, the brown cortex tissue produces a large number of completely isolated pieces of ductal debris. This residue retains its normal coupling type and it can not stick
