Hydrotime analysis of Amaranthus spp. seed germination under salinity condition


Idris, Leni Marlina and Nulit, Rosimah and Qamaruz Zaman, Faridah and Mohd Arifin, Fateen Khaliessa (2020) Hydrotime analysis of Amaranthus spp. seed germination under salinity condition. Journal of Applied Research on Medicinal and Aromatic Plants, 17. pp. 1-6. ISSN 2214-7861


Amaranth (Amaranthus spp.) have gained interest as crop family to be grown under diverse soil conditions such as drought and heat stress. However, the presence of salinity affects crop’s germination process due to reduction in water availability for seeds to germinate. In this study, germination behaviour of Amaranthus hybridus L., Amaranthus viridis L., Amaranthus tricolor L. and Amaranthus giganticus L. under salinity condition were analysed through hydrotime model analysis. Five water potentials in NaCl solution to induce salinity condition (0, −0.3, −0.6, −0.9, and −1.2 MPa) were used in the germination tests. Differences in salinity tolerance were determined in the different species during germination. A. giganticus recorded a lower θH (40.30) and more negative Ψb(50) (−1.55) as well as higher germination rate as compared to the other species. The hydrotime modelling approach applied in this study for the analysis of amaranth species which might help to identify crop salt tolerance at seed germination stage.
