Abstract

This research was carried out in order to test the effects of different SALINITY levels and TEMPERATUREs on GERMINATION, growth and ion relations in PANICUM MILIACEAUM. The experiment was carried out using factorial based on completely randomized design in four replication in Ardabil-Iran. The experimental treatments include six SALINITY levels (0, 25, 50, 100, 200 and 400 mM NaCl) and four TEMPERATUREs (15, 20, 25 and 30°C). Data variance analysis showed that seed GERMINATION of PANICUM MILIACEAUM was significantly (p<0.05) affected by SALINITY levels, TEMPERATURE and their interaction. There was significant difference between maximum seed GERMINATION at 2000C with minimum seed GERMINATION at 1500C and 30°C. On the other hand, maximum GERMINATION percentage was obtained in lowest SALINITY (distilled water). It was substantially reduced and delayed with an increase in NaCl to levels above 50 mM. The increasing of TEMPERATURE above 200C significantly reduced seed GERMINATION percentage. Low levels of NaCl (25-50mM) stimulated shoot and root dry weights of PANICUM MILIACEAUM seedling. However, the highest NaCl levels (>100mM) resulted in a significant decrease in shoot, root and total dry weights of seedling. TEMPERATUREs of 20°C and 25°C resulted in a significant increase in biomass accumulation. The Na+ concentration in shoots and roots significantly increased as NaCl concentration increased. The K+ concentration in roots and K/NA RATIO in shoots and roots was significantly reduced as SALINITY concentration increased. The K/NA RATIO was affected significantly by higher NaCl concentration and TEMPERATURE.
