Última Influence of shoot inclination on irradiance and morphophysiological leaf traits along shoots in cerrado trees with distinct leaf deciduousness Braz. J. Plant Physiol. Souza,João Paulo; Prado,Carlos Henrique B. A.; Damascos,Maria A.; Albino,Ana Lúcia S.. This study investigated the relationship among shoot inclination, irradiance and morphophysiological traits of basal (BL) and distal (DL) leaves in six cerrado trees with distinct leaf deciduousness. Deciduous species showed plagiotropic shoots (44º) and larger leaf area than semideciduous and evergreen species, which showed orthotropic shoots (56º and 63º, respectively). Despite larger leaf area, irradiance at shoot base in deciduous was around 85% in relation to full irradiance, while in semideciduous and evergreen only 23% of irradiance reached on BL. Likewise, maximum net photosynthesis (Pnmax) was similar between BL and DL in deciduous. Contrastingly, semideciduous and evergreen showed significant decreasing of Pnmax in BL. Plagiotropic shoots of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Leaf-life-span; Maximum net photosynthesis; Orthotropic; Self-shading; Plagiotropic.

Plant Physiol. Souza,João Paulo; Prado,Carlos Henrique B. A.; Albino,Ana Lúcia S.; Damascos,Maria A.. The morphology and the biomass allocation in shoots and leaves were investigated in 15 cerrado tree species with distinct leaf phenology growing under natural conditions. Higher values of leaf/shoot ratio on mass base, individual leaf area, leaf area per shoot, leaf display index, and leaf number per shoot length were found in deciduous than in evergreen species. The differences about shoot-foliage relationship across leaf phenological groups could be explained by plagiotropic shoots on deciduous and by erect shoots in semideciduous and evergreen species. Plagiotropic shoots allow similar irradiance along shoots and high biomass allocation in favor of leaves without foliage self-shading in deciduous tree species. The structural differentiation between... Tipo: Info:eu-repo/semantics/article Palavras-chave: Biomass allocation; Cerrado; Deciduousness; Irradiance; Leaf area; Orthotropic; Plagiotropic; Shoot.
