Physiological Characters of Latex from Three Hevea Clones (Reyan 8-79, Reyan7-33-97 and PR107)
橡胶树三个品系（热研8-79、热研7-33-97和PR107）胶乳生理参数的比较研究

The latex physiological parameters,such as total solid content,inorganic phosphorus,thiols,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 clones 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 lat...
