Salt water leads to reduced growth of bean seeds. Scientists at the Agricultural University Plovdiv in Bulgaria tested bean growth in water with sodium chloride, which resulted in a bean seed germination rate of about 50 to 80 percent, water with sodium sulphate at 30 to 70 percent, and deionized water at rates from 80 to nearly 100 percent. Growth and seed respiration, along with germination, declined in the seeds grown in salt water.
