Description:

In a controlled experiment, Salix matsudana cuttings were subjected to three atmospheric temperatures (i.e. control, 0.5 and 1.0 °C above the control, respectively) to explore their short-term plastic responses to simulated atmospheric temperature rise. Warming affected significantly net photosynthetic and transpiration rates, but had no significant impacts on water use efficiency, ratio of sub-stomatal to atmospheric CO2 concentration, maximum quantum yield, water saturation deficit, tissue density, and water loss. Leaf natality and leaf mortality were affected significantly by increasing atmospheric temperature. Total plant biomass, leaf mass ratio, root mass ratio, and canopy productivity index exhibited significant responses to the warming treatments, but obvious differences in the changing details did appear among the four traits. Hence: (1) S. matsudana cuttings were sensitive to small-range atmospheric temperature increases such as 0.5-1.0 °C, which can alter growth and allocation through modifying photosynthetic rate and leaf turnover. (2) Short-term physiological acclimation did not occur in young individuals of S. matsudana. (3) The warming depressed growth of young individuals of S. matsudana to various extents. and W. M. He, M.
