Abstract:

Aims Stipa purpurea is a dominant species of alpine grassland in northern Tibet, a region sensitive to climate change. Environmental variations in temperature, water and atmospheric carbon dioxide (CO2) concentration caused by regional climate change should affect the photosynthetic physiology of plants. Our objective was to investigate the response of S. purpurea to environmental variation. Methods We irrigated natural alpine grassland to imitate rainfall increasing soil moisture and then used a portable gas exchange system (LI-6400) to measure photosynthesis parameters at the irrigated field (H) and a natural field (CK). During measurement, we set three levels of leaf temperature (15, 20 and 25 °C) and gradually elevated CO2 concentration from 50 to 1 500 μmol·mol–1. Important findings CO2, temperature and soil moisture affected photosynthesis parameters of S. purpurea significantly, and interactions were apparent among these three factors. Rising CO2 gradually increased net photosynthetic rate (Pn) until it decreased at extremely high CO2. Higher temperature caused Pn to decrease, but sufficient water supply partially alleviated the negative effect. Sufficient water supply increased Pn. With rising CO2, intercellular CO2 concentration (Ci) increased, transpiration rate (Tr) decreased, water use efficiency (WUE) increased and stomatal conductance (Gs) decreased; higher temperature caused Gs to decrease faster. The photosynthesis parameters above were also impacted by the combined actions of humidity and temperature. Gs was maximized at 20 °C, and sufficient water supply increased Gs further. Ci increased with increased temperature, and this response was more pronounced with sufficient water. Tr was positively correlated with temperature and soil water. Vapor pressure deficit (VPD) was directly proportional to temperature and decreased with sufficient water. Increased temperature and increased water supply made WUE decline. Therefore, increased soil water had compensatory effects on the relationship between high temperature and photosynthetic parameters.
