Diurnal and seasonal gas exchange characteristics of Jatropha curcas leaves
The present study aimed to compare the physiological adaptations of Jatropha curcas under two different climatic variables. The leaf gas exchange and photochemical efficiency measurements were performed in the dry (May–June) and rainy season (July–August). During rainy season, Jatropha presented bet...

Summary: | The present study aimed to compare the physiological adaptations of
Jatropha curcas
under two different climatic variables. The leaf gas exchange and photochemical efficiency measurements were performed in the dry (May–June) and rainy season (July–August). During rainy season,
Jatropha
presented better photosynthetic performance because the conditions of water availability in the soil was slightly more than in the summer season. A greater vapor pressure deficit was measured during the summer season with impaired stomatal dynamics which conferred loss in photosynthesis. As, dry summer season induced photoinhibition of photosynthesis in the leaves of
Jatropha curcas
around mid-day, with rapid recovery in the afternoon may show significant changes in their photosynthetic activities during the seasonal and diurnal cycles of environmental variables. |
