Dissipation of excess photosynthetic energy contributes to salinity tolerance: a comparative study of salt-tolerant Ricinus communis and salt-sensitive Jatropha curcas
The relationships between salt tolerance and photosynthetic mechanisms of excess energy
dissipation were assessed using two species that exhibit contrasting responses to salinity,
Ricinus communis (tolerant) and Jatropha curcas (sensitive). The salt tolerance of R.
communis was indicated by unchanged electrolyte leakage (cellular integrity) and dry
weight in leaves, whereas these parameters were greatly affected in J. curcas. The leaf Na+
content was similar in both species. Photosynthesis was intensely decreased in both …
