Resumo:
The search for new alternatives for use of natural resources emerges the necessity of demand for new raw materials to facilitate development. Regarding the Caatinga biome, the production of knowledge in several areas of knowledge, is of fundamental importance for the generation of public policies that allow environmental management strategies and prioritize, conservation and preservation of biodiversity of the savanna, wealth, endemics, economic and social potential, ecological value. Thus understood, there was a survey on the species Cnidoscolus quercifolius Pohl (faveleira) in areas of the West Seridó of Paraiba State, precisely in Santa Luzia and São Mamede, from march 2009 to february 2011, addressing aspects of the biology of this species, which houses a major socio-environmental value in areas where it occurs. Were monthly data, the study addressed aspects of ethnobotanical faveleira, worked in those communities, aspects of the ecophysiology of the species, which showed anatomical and cytogenetic characteristics, evaluation of photochemical quantum efficiency of photosystem II, evaluation of water potential and study leaf area, biomass of leaves and fruits, phytosociology the woody layer in the savanna areas of West Seridó Paraiba and phenology of populations faveleira considering seasonal rainy and dry periods. The species C. quercifolius presented, according to the results, a biological dynamics that fits well with environmental factors in which it unfolds, showing a marked seasonality for aspects ecofisológicos studied.
