Heterogeneous light environments induce plasticity in leaf morphology and photosynthesis of two sympodial bamboo species

Introduction: Light heterogeneity is common in forest ecosystems. It arises from both horizontal (orientation) and vertical (canopy layer) gradients, driving adaptive strategies in plant morphology and physiology. Methods: were studied to clarify the adaptative mechanism of these two sympodial bamboo species to heterogeneous light environments. Results and discussion: attained precise acclimation via morphological and physiological plasticity. This study reveals a consistent increase in leaf investment under high light conditions in two sympodial bamboos, alongside species-specific variations in the extent of their morphological and physiological plasticity. These findings provide a theoretical basis for the sustainable management of bamboo forest ecosystems.
