Abstract

Micro-cut is a new exploiting technique.There is a significant correlation between flow area and latex yield.Turgor pressure of trunk in the flow area on a rubber tree (Hevea brasiliensis) Clone PR107 with 1/8s↑d/4 tapping system was measured at NO.7 trial team, Chinese Academy of Tropical Agricultural Sciences.The result showed that there were differences among turgor pressure of different loci of trunk, and all of them decreased less after tapping.Turgor pressure of trunk keeping a comparative higher level is one of factors that flow of rubber trees with micro-cut and gaseous stimulation kept longer.

Key words： Hevea brasiliensis; micro-cut; flow area; turgor pressure
