Primary nerve (vein) density influences spatial heterogeneity of photosynthetic response to drought in two Acacia species

Sommerville, Katy; Gimeno , Teresa E; Ball, Marilyn


We examined the relationship between variation in phyllode nerve density and the spatio-temporal response of the photosynthetic apparatus to water-stress in two Acacia s.str. species with contrasting nerve patterns: Acacia floribunda (Vent.) Willd and Acacia pycnantha Benth. A. floribunda had greater primary nerve density than A. pycnantha and also showed greater spatial homogeneity in photosynthetic function with drought than phyllodes of A. pycnantha. A. pycnantha had lower maximum quantum...[Show more]
