Resumo: The objective of this work was to determine the effect of climatic seasonality on physic nut (Jatropha curcas), in field, under semiarid climate conditions. Stomatal conductance (gs), transpiration (E), soluble leaf carbohydrates (SLC), free amino acids (FAA) and total proteins (TP) were measured in leaves, in a commercial plantation in Northeast Brazil, during the summer and autumn. Plants showed high gs and E, as well as SLC, FAA and TP contents in the summer, which gradually decreased with the lower temperatures and photosynthetically active radiation during the autumn, despite the higher water availability. Even in conditions of adequate water availability, the combination of low temperatures and reduced light drastically decreased foliar metabolism.

Condutância estomática (gs), transpiração (E), carboidratos solúveis (SLC), aminoácidos livres (FAA) e proteína total (PT) foram mensurados em folhas, em plantio comercial, no Nordeste brasileiro, durante as estações de verão e outono. As plantas apresentaram altos valores de gs e E, bem como de SLC, FAA e PT no verão, que diminuíram gradualmente durante o outono, com o decréscimo da temperatura e da radiação fotossinteticamente ativa, apesar da alta disponibilidade hídrica. Mesmo em condições de adequada disponibilidade de água, a combinação de valores reduzidos de temperatura e luminosidade reduz drasticamente o metabolismo foliar.
