Abstract

In this study, the effects of seaweed extract (Ascophyllum nodosum) on seed germination stimulation and growth indices in chickpea were studied. A factorial experiment was performed on the basis of a completely randomized design with 3 replications. Treatments consisted of seaweed extract at four levels (0, 1. 5, 2. 5 and 3. 5%) and drought stress at four levels (0,-0. 3,-0. 6 and-0. 9 MP). Drought stress was induced by PEG 6000. Results showed that drought stress at-0. 6 and-0. 9 MP reduced the germination traits significantly compared with the controls. Seaweed extract at 2. 5 and 3. 5% resulted in a significant increase in the germination percentage (+18%, +24%), germination rate (+15%, +20%), seedling length (+13. 3%, +15. 7%), radicle area (+10. 4%, +12. 8%), radicle diameter (+14. 2%, +25%), plumule length (+14%, +16. 6%) and plumule dry weight (+10. 3%, +12. 6%). Under non-stress and-0. 3 MP, seaweed extract levels at 2. 5 and 3. 5% could significantly increase the germination vigor, seed vigor index, consumed endosperm, radicle length and radicle dry weight. The application of seaweed extract at 3. 5% improved the germination vigor, seed vigor index and radicle dry weight under-0. 6 MP conditions. It also improved the consumed endosperm, length and radicle dry weight in samples affected by-0. 9 MP conditions. According to the results, the use of seaweed extract (Ascophyllum nodosum) in the seed germination of beans is recommended for the reduction of the negative effects of drought stress.
