Ecophysiological response of Astronium fraxinifolium (Anacardiaceae) in degraded and non-degraded brazilian Cerrado

Abstract Plants native from Cerrado generally have peculiar characteristics that allow tolerating water and nutritional stress. Astronium fraxinifolium is a Anacardiaceae tree of Brazilian Cerrado. The aim this research was to characterize A. leaves morphophysiologically, in order recognize related acclimatization the species different soil conditions. Two populations were sampled study areas, A1 (Degraded Soil) A2 (“Undegraded Soil”). Nitrogen compounds, total carbohydrates, chlorophyll, content, stomatal density gas exchanges quantified, comparing areas. A high number stomata observed on abaxial surface leaves, with higher occurring individuals. values chlorophyll boron content significantly plants. It’s possible lowest concentration plants production. Regardinf other analysis, there weren’t significant differences between results show undergoes changes production but liquid photosynthesis isn’t impaired, considering low being compensated by density. Thus, these may be result acclimating environmental conditions which it’s exposed.
