摘　　要： 为探讨橡胶树高产的机理,分析了不同产量水平橡胶树(PB86)砧木和接穗胶乳养分含量的差异。通过对干含、总固形物、硫醇、糖、无机磷、粗蛋白等的比较分析,结果表明:(1)橡胶树自身的砧木与接穗之间,除超高产橡胶树砧木中蔗糖、硫醇的含量极显著高于接穗外,其他养分含量在超高产、高产橡胶树自身的砧木与接穗之间差异并不显著,但一般单株橡胶树接穗胶乳中干胶含量、总固形物含量均极显著高于自身砧木。(2)不同产量水平的橡胶树之间,产量越高的橡胶树其砧木胶乳中各种养分的含量也越高,超高产橡胶树砧木中干含、总固形物、硫醇、糖的含量均极显著高于高产树和一般单株。(3)不同产量水平橡胶树接穗间硫醇、蔗糖、粗蛋白的含量差异均未达极显著水平。相对而言,与嫁接后橡胶树砧木与接穗之间的营养物质运输对橡胶树产量的影响相比,嫁接时优良砧木材料的选择更为重要。 The change of the dry rubber content, soluble solids content, thiol content, sucrose content, inorganic phosphorus content and protein content in the latex of rootstock and scion on different yield rubber budding tree were analysis in the article for discussing the relationship between nutrient content and yield. The results showed that：（1） There was no difference between the rootstock and scion in supper-high-yield and high-yield rubber tree beside the thiol content and the sucrose content in rootstock of supper-high-yield rubber tree was very significantly higher than the scion itself, but the dry rubber content and the soluble solids content in scion of CK was very significantly higher than the rootstock itself.（2） The nutrient content in rootstock of higher yield rubber tree were higher relatively, the dry rubber content, soluble solids content, thiol content and sucrose content in supper-high-yield rubber tree were very significantly higher than the highyield and CK.（3） The thiol content, sucrose content and protein content had no very significantly difference in the scion. The good rootstock material was more important than the nutrient transportation between the rootstock and scion for higher yield on rubber budding tree.
