Jatropha curcas has been considered as a potential oil source for biodiesel production in tropical and subtropical areas. The relationships between water deficit-induced nocturnal acidification and leaf succulence, gas exchange rates and water relations in leaves of J. curcas were accessed in a greenhouse experiment. Two genotypes, from regions of Brazil with contrasting climate (CNPAE183, from a dry and hot tropical climate and CNPAE191, from a humid subtropical climate), were maintained under full irrigation or were subjected to water deficit for 49 days followed by recovery for 7 days. Leaf relative water content decreased with water deficit from 85.4 to 77.5%, in both genotypes. Pre-dawn leaf water potential decreased from - 0.5 MPa in irrigated plants - 1.0 MPa (in CNPAE183) and to - MPa (in CNPAE191). Slow and less intense decrease of leaf gas exchange in CNPAE191 than in CNPAE183 suggests a high effective water use under water deficit in the former. Leaf nocturnal acidification increased 4.3-fold in water deficit plants of both genotypes and a positive correlation between nocturnal acidification and leaf succulence, expressed as fresh mass per dry mass, was observed. Water deficit-induced nocturnal acid accumulation and a positive correlation between nocturnal acidification and leaf succulence were thoroughly demonstrated. While such nocturnal acidification may be related to osmotic adjustment, its correlation with leaf succulence suggests a weak CAM-cycling activity in leaves of J. curcas which, along with other water-conserving mechanisms, may help to explain the widely reported drought tolerance of this species.
