Abstract

Abstract: In order to explore the effects of Hydrangea on ex situ conservation environment, the effects of temperature and light on physiology and morphology of two Hydrangea species, Stratford and Todi, were studied. The results showed that the photosynthesis of Stratford was stronger than that of Todi under four temperature and light conditions. The stomatal conductance of Stratford was higher than that of Todi under high temperature and high light, high temperature and low light and low temperature and high light. The transpiration rate of Todi was higher than that of Stratford under high temperature and high light, high temperature and low light and low temperature and low light; the specific leaf weight of Stratford was more sensitive to high light, while the root top ratio of Stratford was lower than that of Todi under different temperature and light. The stomatal area of Stratford was lower than that of Todi, but the stomatal density of Stratford was higher than that of Todi. The plasticity indexes photosynthesis, stomatal conductance and transpiration rate of Stratford were relatively small, and its self-regulation ability was stronger. It was more receptive to the changes of the external environment. When encountering environmental changes, its physiological characteristics would be more stable, and its survival ability and environmental adaptability were stronger than Todi.

Key words: Hydrangea, environmental adaptability, temperature, light, physiology and morphology
