| 摘 要： | 比较分析了4个胶木兼优橡胶树品系的生长量、初产期干胶产量与排胶生理参数。结果表明:热试99-10、热试99-8生长较快,热试99-2、热试99-8、热试99-10干胶产量较高;4个品系间生理参数存在一定的差异,且季节性变化明显,其中热试99-2、热试99-8具有与高产相适应的生理基础,热试99-10生理状况良好,但胶乳再生能力较差,而热试99-5的生理基础可能较适合乙烯利刺激割胶。

| Abstract: | An analysis was made of the growth and yield of four latex/timber clones at initial production stage and their physiological characteristics. The results showed that Reshi99-10 and Reshi99-8 had optimum growth rate while Reshi99-2, Reshi99-8 and Reshi99-10 gave a higher yield. The four clones were different in physiological characteristics, notably with season. Reshi99-2 and Reshi99-8 displayed physiological parameters of high yield; Reshi99-10 had better latex physiological parameters but poor latex regeneration stability; Reshi99-5 had the physiological parameters that might be suitable for stimulated tapping system. |
