Temperature is a regulator of leaf production in the family Dipterocarpaceae of equatorial Southeast Asia.

ABSTRACT:

Premise

Leaf phenology is an essential developmental process in trees and an important component in understanding climate change. However, little is known about the regulation of leaf phenology in tropical trees.

Methods

To understand the regulation by temperature of leaf phenology in tropical trees, we performed daily observations of leaf production under rainfall-independent conditions using saplings of Shorea leprosula and Neobalanocarpus heimii, both species of Dipterocarpaceae, a dominant tree family of Southeast Asia. We analyzed the time-series data obtained using empirical dynamic modeling (EDM) and conducted growth chamber experiments.

Results

Leaf production by dipterocarps fluctuated in the absence of fluctuation in rainfall, and the peaks of leaf productio
