Insufficient water is a leading environmental problem that affects overall crop development, productivity, and sometimes total crop failure. It brings a number of morpho-physiological and cellular disturbances. The purpose of this study was carried out to assess the effects of photosynthetic pigments and antioxidative enzyme activities of Saccharum spontaneum cv. GX83-10 plants during mild to severe water stress conditions. After 90 days of bud setts germination, S. spontaneum plants were sustained up to 15 days of withdrawing water. Our results indicated that the stressed plants were negatively affected, such as growth, biomass, photosynthetic loss, and significant reduction in photosynthetic CO2 assimilation rate. Severe water stress enhanced the level of osmolytes, i.e., proline, soluble protein, soluble sugar, and malondialdehyde, as well as catalase, peroxidase, and superoxide dismutase enzyme activities. Antioxidative enzyme activities in S. spontaneum plant leaves were improved and enhanced the metabolism of superoxide, leading to enhanced water stress tolerance efficiency. The present findings may help in better understanding of S. spontaneum antioxidative defense systems in drought-stressed conditions. [ABSTRACT FROM AUTHOR] |
