The Effect of Osmopriming on Germination and Seedling Growth of Glycine Max L. Under Salinity Stress
Abstract
Soybean (Glycine max L.) is a staple food crop in Indonesia. Soybean plants have decreased in quality and production due to salinity factors. Planting media with high salinity conditions have limited potential for plant cultivation, but each plant has different resistance and adaptability. Osmotic priming of seeds or osmopriming could increase plant resistance to salinity. This experiment was conducted at Universitas Muria Kudus Field. The objective of this study was to determine the germination and seedling growth of Glycine max L. as treated by NaCl osmopriming. A randomized complete design was used with two factors. The first factor was osmopriming concentration which consisted of the control, 50 mM (K1), 100 mM (K2), and 150 mM (K3). The seeds of the control did not receive osmopriming NaCl treatment. The second factor was osmopriming duration which consisted of 24 hours (T1) and 48 (T2). The results showed that the treatment of osmopriming with a concentration of 50 mM NaCl for a duration of 24 hours had a positive impact on seed germination under salinity conditions of 150 mM NaCl. However, this did not significantly affect the seedling growth in salinity conditions of 150 mM NaCl.
