Drought stress response in Jatropha curcas: Growth and physiology
Lead person: M. Margarida Oliveira
Affiliated institution: Instituto de Tecnologia Química e Biológica ✉ (+351) 21 446 91 00
Objective: Tolerance to drought remains poorly described for Jatropha curcas accessions from different geographical and climatic origins. To address this issue we studied the response of two J. curcas accessions, one from Indonesia (wet tropical climate) and the other from Cape Verde islands (semi-arid climate). Potted seedlings (with 71 days) of both accessions were subjected to continuous well watered conditions (control) or to a drought stress period followed by re-watering.
