SALT TOLERANCE STUDIES ON PANICUM ANTIDOTALE RETZ. EJAZ RASUL, TAHIR RIZWAN SOHAIL AND KHALID MAHMOOD* Abstract: Salt tolerance of Pallicum antidotale Retz., was studied using gravel culture with root medium electricaI conductivity (EC) levels ranging from 3 to 20 dS/m. Salinity decreased the seed germination and plant powth. A 50% relative-to-control reduction in dry mass yield was observed at EC 15.9 dS/m. Na contents in plant shoots increased whereas K contents decreased in response to increasing salinity. Ca concentration exhibited non-significant variation over control. CI contcnt alongwith N and protein percentage increased with increasing root medium salinity.
