What leads to rubber leaf senescence in the northern edge of the Asian tropics?

The rubber tree (Hevea brasiliensis) belongs to the evergreen broadleaved species in its native ranges, but it has a concentrated leaf senescence period after it was introduced to the Asian tropics. The mechanism behind the leaf senescence is still unclear. Models for predicting leaf senescence dates of this introduced tree have been rarely explored. This study proposed a series of models to identify the main abiotic drivers for the rubber leaf …
