Growth response of Vigna ambacensis L. seedling to the interaction between nitrogen source and salt stress
| Vigna ambacensis plants grown hydroponically in a Hoagland nutrient solution with either nitrate or ammonia as a source of nitrogen and NaCl a 0,40, 80 and 160 mM concentrations showed reduction in all growth parameters where ammonia was used as compared to nitrate as a nitrogen source. Salt decreased the growth of plants. Plants grown in nitrate were more salt tolerant as compared to ammonia especially at 80 and 160 mM NaCl level. High salinity conditions reduced calcium and potassium contents in shots with a increase in sodium which was higher (80 m mu l) in NH4+-N as compared with NO3-1-N source. |
