Purified drinking water, ocean water samples,M-201 Oryza sativa (rice seeds). Dilute the ocean water samples by 1/4, 1/2, and 3/4 with the purified drinking water. Then use these samples to irrigate the rice seedlings twice a day for nine days, once the seeds have started to sprout. Count, measure, and record growth of rice seedlings every other day.
The seedlings irrigated with water diluted with 1/4 ocean water(containing salinity levels of 6.7 parts per million) had very little affect on the seedlings growth when compared to the control. The test sample irrigated with the water diluted with 3/4 ocean water(containing salinity levels of 8.8 parts per million) had a very damaging affect on the young seedlings.
My conclusion is that smaller amounts of salinity from ocean water would not make a strong impact on the growth and stand density of rice seedlings.
The project was to find tolerance of different salinity levels from diluted ocean water on rice seedlings growth.
