Abstract:

Ethephon has been widely used to stimulate latex tapping in the natural rubber production for its remarkable promotion of the yield, but the mechanisms of how it works are not clear and, now it is still a hot subject on mechanisms of latex regeneration and latex flow. This paper summarizes the results of research on yield-increasing mechanism stimulated by ethephon on H. brasiliensis from various disciplines and aspects. It is showed that the reasons are multifaceted, and aquaporins probably play a role in the rubber tree yield-increasing mechanism..

Key words: Hevea brasiliensis, ethephon, yield-increasing mechanism
