Responses of photosynthetic rate of lucerne and the mechanisms under cutting at different water availabilities

摘要：

Introductoion The regrowth after cutting (defoliating) is essential to the utilization of forage and grassland. After forage cutting, the residue has to change its original function to adapt new situation. Some clue showed that photosynthetic rate ( Pn) of the aboveground part would increase after cutting and would keep higher for a longer period ( Nowak and Caldwell,1984; von Caemmerer and Farquhar, 1984).
