| 摘 要： | 以3个橡胶树引进品种为研究对象,‘热研73397’和‘RRIM600’为对照,测定胶乳产量、干胶含量、排胶初速度及胶乳中蔗糖、无机磷、镁离子和硫醇等生理参数,比较分析不同品种的产排胶特性。结果表明,各测定参数在品种间存在较大差异。‘热试09-5’干胶产量高,蔗糖含量、排胶初速度低于‘热研73397’,干胶含量、硫醇含量、无机磷含量差异不显著,认为该品种产胶潜力大,胶乳稳定性好,排胶快,糖利用率高;‘热试09-6’干胶产量一般,与‘RRIM600’相比,干胶含量、堵塞指数高,排胶初速度和蔗糖含量差异不显著,认为该品种有较好的产胶潜力,但胶乳代谢强度低,可考虑通过刺激提高代谢强度,达到增产;‘热试09-7’干胶产量低,与‘RRIM600’相比,干胶含量高,排胶初速度低,蔗糖含量相当,认为该品种排胶障碍,糖的利用效率低,是否可以通过刺激割胶增加产量还需要进一步的试验验证。

| Abstract: | The latex physiological characteristics of three introduced rubber clones, such as latex yield, dry rubber content, initial flow rate, sucrose content, phosphorus content, Mg2+ content, and thiol content, were measured and analyzed. The results showed that, compared to the control clone ‘Reyan 73397’ and ‘RRIM 600’, there were significant differences among the rubber clones. According to high dry rubber yield, good latex stability, fast rubber-discharging, and high sugar utilization rate, ‘Reshi 09-5’ showed high-yielding potential, but the content of sucrose and initial flow rate of ‘Reshi 09-5’ were lower than that of ‘Reyan 73397’, and there was no significant differences in dry rubber content, thiol content and phosphorus content between them. ‘Reshi 09-6’ had higher dry rubber content and plug index than ‘RRIM 600’, and there was no significant differences in initial flow rate and sucrose content between them. All of these showed that ‘Reshi 09-6’ had better potential in latex production, but a low metabolic intensity, so the production can be increased by stimulated tapping. Compared to ‘RRIM600’, ‘Reshi 09-7’ had lower dry rubber yield, initial flow rate, and higher dry rubber content, which showed high latex discharging barrier and low sugar utilization efficiency, so it need to be further tested whether the yield can be improved by stimulated tapping in ‘Reshi 09-7’. |
