Homeostasis of respiration under drought and its important consequences for foliar carbon balance in a drier climate:insights from two contrasting Acacia species

Gimeno , Teresa E; Sommerville, Katy; Valladares, Fernando; Atkin, Owen


Under drought, when photosynthesis (A) is impaired, foliar respiration (R) becomes crucial to estimate plant carbon balance. However, the effects of drought on R remain unclear and little is known about differences between congeners with divergent anatomy. In this study we compared the physiological response to imposed drought in plants of two Acacia species: Acacia pycnantha Benth. and Acacia floribunda (Vent.) Willd. in a controlled environment. We subjected half of the plants to two...[Show more]
