通过测定胶乳生理参数和胶乳产量,首次比较分析了橡胶树(Hevea brasiliensis)3个品系(热研7-33-97、热研8-79和PR107)的产排胶特性.结果表明,3个品系在初产期、未施乙烯利刺激时的胶乳产量和生理参数差异明显,胶乳产量为热研8-79>热研7-33-97>PR107;蔗糖转化酶活性与胶乳产量显著正相关,但其它生理参数与产量的相关性均不明显;割胶前一段时间的降水量是影响割次胶乳产量的重要因素,其中PR107品系受影响最大.这说明橡胶树品系的产排胶具有特异性,需要建立品系适宜性割胶制度.

The latex physiological parameters, such as total solid content, inorganic phosphorus, thiob, sucrose content, and invertase activity, and the yield in three clones (Reyan 7-33-97, Reyan 8-79 and PR107) of Hevea brasiliensis were analyzed. The results showed that there were significant difference in latex yield and physiological parameters among the three cbnes at early latex productive stage and tapped without ethrel stimulation. The latex yields were in order as: Reyan 8-79 > Reyan 7-33-97 > PR107. The activity of latex invertase had positive correlation to latex yield (P<0.01), while the other physiological parameters had not. The cumulative rainfall before tapping had different effects on the three clones, in which PR107 had the most influence, so it seemed to be an important factor in latex yield. These results suggested that there were specificity in latex production among clones, and it needs establish clone-suitable tapping systems.
