摘　　要：对热研７—３３—９７、ＲＲＩＭ６０＇、ＰＢ８６、海垦１号。天任３１４５等５个品系的一年生幼苗的橡胶转移酶活性于不同月份进行测定，其结果基本一致，与橡胶产量呈正相关。对热研４３—（８—７９）、ＲＲＩＭ７１２、合口３—１１。南强１—９７等１３个品系的橡胶树幼苗的橡胶转移酶活性的测定结果表明，橡胶转移酶可以作为橡胶树产胶能力的重要指标，对橡胶树产量进行早期预测。为了适应早期预测工作，建立了简便快速的全胶乳橡胶转移酶活性的测定方法。Rubber transfercqse activity of one year old plants of Hevea clones Reyan 7—33—97，RRIM600，PB86，Haiken 1 and Tianren 3145 determined in various months was found consis-tent in general，and showed a positive relation to rubber yield．Determination of rubber trans-ferase activity of one ye，ar old plants of 13 clones such as Reyan 43—（8—79），RRIM712，Hek-ou 3—11 and Nanqiang 1—97 also revealed that rubber transferase can be used as an importantindex of latex producing abbility for prediction of latex yield at nursery statge. By employing thismethod,early prediction of latex yield of five clones offered for evaluation proved accurate in gen-eral.
