In this study the Brassica Rapa will be tested to see if salt water effects it's growth. Data will be
taken from four different types of groups: distilled water; 0.25% of sodium chloride; 1.00% of sodium
chloride; and 4.00% of sodium chloride. Data will be collected in a twenty-two day span, every other
day, to document changes in growth and appearance.
The Brassica Rapa, well known as the tulip, cabbage, and spinach has an unknown origin but is
suggested to be from the Eastern Mediterranean to Pakistan and Eastern China (www.prota.org). In the
time of Alexander the Great (356 323 B.C.) the turnip was described throughly which implies that
around his time the Brassica Rapa spread from the Middle East and Persia down to south-eastern Asia
and Africa via trade routs (www.prota.org). Today, species of the Brassica Rapa are found world-wide,
with documents of coming to America in the 1500's (FloriData, Home Greenhouse Kits).
