Ecophysiological responses of Abies fabri seedlings to drought stress and nitrogen supply.

abstract：:Plants in the savanna-valleys in Southwest China are annually exposed to different combinations of multiple stresses from the hot-rainy, to chill-dry, and to warm-dry seasons. This study monitored seasonal changes in photosynthesis and photoprotection in an evergreen oak (Cyclobalanopsis helferiana) from one of these ...
