Responses of gas exchange and growth in Merkus pine seedlings to expectedclimatic changes in Thailand

摘要

Responses of gas exchange and growth in Merkus pine (Pinus merkusii Jungh. et de Vriese) seedlings to changing climate were analysed for high- and low-altitude sites in Thailand. A gas exchange model, based on the optimality approach, derived the effect of drought from the probability of rains. A carbon-and nitrogen-balance growth model applied structural regularities of a tree and a modification of functional balance between foliage and fine roots as growth-guiding rules. Adaptation to local climates was incorporated in the models.
