| 中文摘要: |
| 以橡胶树PR107 为试验材料，比较了不同浓度乙烯气刺微割下的产量和胶乳生理变化。通过对气刺微
割中不同乙烯浓度的产量和生理效应的分析，发现橡胶树PR107 气刺微割的增产效应与乙烯气体浓度并不成比例，
乙烯气体浓度过高达不到增产效果。采用高浓度（超过60%）乙烯刺激割胶，会造成胶树生理亏缺，干含下降，产量不
稳定。采用低浓度（<40%）的乙烯刺激割胶，胶树生理性状较平稳，胶乳干含稳定，且可获得较高的产量。 |
| 英文摘要: |
| In this study, rubber tree clone PR107 was selected, and the yield and physiological features under microtapping
with different concentration of ethylene were compared. The results showed that no significant correlation was found
between the rubber yield and ethylene concentration applied by micro-tapping on PR107. Too high level of ethylene
couldn't increase yield. The physical deficits, dry rubber content (DRC) decline, and yield fluctuate of rubber tree were
induced by micro-tapping with high level of ethylene (greater than 60%). Instead, micro-tapping with low level of ethylene
(less than 40%) gave good yield, stable DRC and steady physiological features of rubber tree. |
