Seed Germination of Populations of Wild Wheat Species, Aegilops biuncialis and Ae. triuncialis: Effects of Salinity, Temperature and Photoperiod

Abstract: In this research, seed germination of populations of wild wheat (Aegilops) species (Bi-1 and Bi-2 populations of Ae. biuncialis and Tri-1 and Tri-2 populations of Ae. triuncialis) was investigated under different salinities (0-675 mM NaCl), temperatures (15/25 and 25/35°C, night/day) and photoperiods (in dark and in 12 h light: 12 h dark), using a completely randomized block design. No seeds germinated at 675 mM NaCl. Seed germination was partly or completely inhibited in all populations with an increase in salinity and this inhibition was more important at 25/35°C than in 15/25°C temperature regime. The highest germination percentages occurred at 15/25°C for all populations. The effect of light differed depending on population, temperature and salinity. Seed germination of Ae. biuncialis populations was similar in light under salinity and temperature interactions. Seed germination of Bi-2 population was higher than Bi-1 population in dark. Differences between Tri-1 and Tri-2 populations were remarkable in both photoperiods at 25/35°C temperature regime. At 15/25°C, the detrimental effect of light was determined in all populations at high salinity levels. Seed germination of only Bi-1 population in light was significantly greater than in dark in all NaCl concentrations at 25/35°C.
