Same letters are not significantly different at probability (p<5%) error by Duncan's multiple test. Values are means ± SD=standard deviation FG%= final germination percentage, GVe = germination velocity, GE= germination energy, SG=speed of germination, GPV= germination peak value, GI=germination index, GC= germination capacity, GV=germination value, MGT=mean germination time, RL=root length, SL = shoot length, TDB= total dry biomass, and GVI= germination vigour index.
