摘要: An analysis of biomonitoring quantum efficiency Aspidosperma pyrifolium (Mart.) and Poincianella pyramidalis (Tul.) L. P. Queiroz, was measured between 2012 2013 in order to understand possible strategies survival for species under extreme drought conditions Soledade City, semiarid region Paraiba. Three leafs the middle portion randomly arranged three individuals populations exposed intense light, a total nine replicates per population were chosen. The values recorded an increase July (0.652), August (0.785) September (0.667) 2012, response increased local precipitation occurred June 2012. Similar observed A. which showed mean 0.745 0.685 same year. greater resistance water stress, with (0.712), December compared (0.353). plant exhibit seasonal deficit experienced study period.
