| Abstract/Contents: | "The USGA sponsored research studies are ongoing at Karsten Turfgrass Research Facility, Department of Plant Sciences, College of Agriculture and Life sciences, the University of Arizona. This specific experiment was conducted in a greenhouse to evaluate growth responses, in terms of shoot and root lengths, fresh and dry matter (DM) weights, as well as nitrogen uptake, of various saltgrass clones collected from different southwestern states of the US under sodium chloride (NaCl) salinity stress conditions. The results can be summarized as follows: The results of this experiment, confirmed that saltgrass has a high salt tolerance, and is a true halophyte. Although shoot growth numerically decreased under salinity stress compared with the control plants, the growth reduction at this level of salinity, which is considered moderate for saltgrass growth, was statistically not significant. Root length, root fresh weigh., and root dry weight in plants grown under saline condition increased. The amount of dry matter produced is the most significant result as it is a direct representation of saltgrass' ability to grow under highly saline conditions. Based on the results of this experiment, each of the tested varieties had a high degree of salt tolerance. Based on the partial results of the 15N analysis, all the clones accumulated significant amounts of nitrogen in their tissues under salinity stress condition." |
