摘要
研究未刺激、乙烯利刺激、乙烯气体刺激胶树微割排胶影响面内不同高度部位胶乳的蔗糖、无机磷、总固形物含量和水势,并比较分析同种处理割胶前后及不同处理间割胶前后胶树胶乳中这些生理参数的差异变化,结果表明:乙烯气体刺激较其他2种处理能够较明显扩大胶树排胶影响面,有利于增加胶树胶乳产量。并提出用开割前和停排后的胶乳干含差来指导割胶生产。
Minicut with gaseous ethylene stimulation is a new tapping method which can increase latex yield.To investigate the physiological mechanism,sucrose,phosphorus and total solid content,and its water potential were measured in the latex from flow area of rubber trees by micro-cut with gaseous ethylene,ethephon treatment or without treatment control,respectively.Differences of these physiological parameters were analyzed between before and after tapping in same treatment,as well as among different treatments.The results showed that the gaseous ethylene stimulation significantly promoted latex yield by increasing rubber flow area of trees.It was found that the difference of dry latex content between before tapping and after stopped flow could be used as an indicator in managing tapping production.
