the effects of seed priming techniques in improving germination and early seedling growth of aeluropus macrostachys

the purpose of this study was to examine the evaluating the potential of seed priming techniques in improving germination and early seedling growth of aeluropus macrostachys under salinity stress condition. this study was performed at the islamic azad university in baft city which is located in southeast of kerman province (2250 meters above the sea level, 92º 17 n latitude and 56º 36 e longitude, and 220 mm annual rainfall). this experiment was conducted a completely randomized design. the factors examined include four levels of seed priming, control (without priming) with nacl and cacl2 kcl and five salinity levels (0, 4, 8, 12, 16 desysimenz/m), respectively.in this experiment traits such as germination percentage, speed of germination, radicle length and shoot length were measured. data were analyzed by using general linear models procedure of sas software. in addition, means were compared using duncan’s multiple  range test. results of this study showed that different seed priming treatments improved shoot and radicle length, germination percentage and speed of germination of aeluropus macrostachys specie.
