Abstract

The effect of salinity stress on seed germination in 3 rangeland species of S rigida, S.richteri, S.dendroides and to determine the salt tolerant species was investigated in this study. All three species are suitable for grazing as well as reclamation of arid and semi arid lands. This research was conducted using a factorial experiment based on CRD design with 4 replications. Experimental treatments included a combination of three species along with 13 salinity levels of 0,50,100,150, 200 ,250 ,300, 350 ,400 ,450 ,500 ,550 and 600 MM concentrations. The results indicated that S.dendroides and S.rigida were more tolerant than S.richteri. While S.dendroides and S.rigida were tolerant to 600 MM, S.richteri was tolerant only up to 350 MM. With increase in salinity GERMINATION PERCENTAGE and GERMINATION RATE were reduced with the maximum germination occurring at the lowest salinity level. Increasing salt concentration up to 200 MM did not significantly decrease radicle length in S.dendroides, but in S.rigida with an increase in salt concentration (up to 50 MM) radicle length increased. Salinity increase in S.richteri cauased decrease in radicle length. So S.richteri is shown to be more sensitive to high salinity levels at germination stage as compared to the other two.
