In the current study, bioadsorbent based cellulose, CMC-g-P(DMEMA) hydrogel, was prepared, characterized and investigated for alleviating the bad effects of drought stress on the growth and biochemical traits of sunflower plants. The impact of water stress on plant pigments, total phenol, proline content, enzymatic responses and some growth characteristics of sunflower plants was investigated. The results showed that CMC-g-P(DMEMA) hydrogel decreased the drought stress on growth characters, chlorophyll content and total phenol contents. The lengths and fresh weight of shoot, pigments and phenol contents was highly improved. These results displayed that CMC-g-P(DMEMA) hydrogel had good water retention and is expected to have potential applications in sustainable modern agriculture.
