The biology 151 lab groups at the University of North Dakota conducted an experiment to find out the effects of sodium chloride on the plants that are not naturally grown in salty soils. Wisconsin Fast Plants, which are naturally grown in low to no sodium chloride concentrated soils, were planted and grown in several different salt concentrations to discover whether the plants grew better or worse in given soil concentrations. After multiple measurements, the results came back that the plants do not do well in concentrations greater than one percent salt concentration, but grew the best in a concentration of 0.37 percent.

The groups split into many smaller groups so that they could test the plants in many different sodium chloride concentrations. Each biology lab group spilt their class into six groups. The first group created a soil containing 6 percent sodium chloride, salt, by adding 15 milliliters of sodium chloride to one cup of soil. The next group took ¼ a cup of the six percent soil and mixed it with ¼ cup of plain soil making soil containing a three percent sodium chloride concentration. The group after that took ¼ cup of the three percent soil and mixed it with ¼ cup of plain soil making soil containing a 1.5 percent sodium chloride concentration. The remaining groups performed the same procedure as groups two and three making soils with 0.75, 0.37, 0.18, 0.09, and 0.045 percent sodium chloride concentrations. Each of the six groups created two samples either two samples of various salt concentrations or a salt concentration and a control with a zero percent sodium chloride concentration in the soil. Once all the groups created the correct soil concentrations, they placed each soil concentration into four small, Styrofoam wells. In each well the groups placed two seeds, Wisconsin Fast Plants, into each well. They then covered the seeds in extra soil of the correct sodium chloride concentration. In total, there where 64 seeds planted into various sodium chloride concentrations. The extra 16 seeds …show more content…
The Wisconsin Fast Plants seeds, which naturally do not grow in high sodium chloride concentrations, did not grow well in the pods with a higher concentration. The overall germination percentage for the plants planted in three highest sodium chloride concentrations, one and half, three, and six percent soil concentrations was zero percent. Due to the 12 plants in the highest concentrations not germinating there were no measurements for any of the recorded categories other than germination percentage. In remaining sodium chloride concentrations, plants could still germinate. Unlike what was suspected, the plants grown in the lowest or no sodium chloride concentration did not have the greatest percent of germinated seeds. The control, 0 percent, germinated only around 62 percent of seeds. The 0.045 percent germinated ¾ of its seeds. The 0.09 percent group grew 62.5 percent of its seeds. The 0.18 percent grew 87.5 percent of its seeds. The 0.75 percent group grew half of its seeds. The group that germinated the highest percent of its seeds, germinating 100 percent of its seeds, grew in a 0.37 percent concentration of sodium
