Desert remediation: selecting for salt tolerant native grasses.

The purpose of this project is to select for salt tolerance of buffalo grass, wheat, and blue grama seeds. This research focuses on the efforts to select salt tolerant grasses better suited for use on marginal land or poor quality previously irrigated land. Prepare agar. Place disinfected seeds in agar. Place germinated seeds in test tubes of 1%, 2%, and 3% salt solutions. Let plants grow for 4 weeks. Take plants and place them on a scale and weigh them immediately after taken out of test tube and record the results. Dry plants in an oven and weigh the plants on a scale and record the results. Calculate the percentage of water loss. According to D. J. Hansen published in the American Journal of Botany, relative water content of the plant tissues decreases with increasing salinity levels indicating less water [loss] per gram of fresh tissue as the high salinity levels rose. This leads me to conclude from my data, that although the higher salinity levels affected the grasses, it also means that they could survive. Buffalo grass, blue grama, wheat, and salt grass would be successful if selected for use on marginal land or poor quality previous irrigated land.
