Effects of Road Salt on Germination and Growth
- Materials and methods section
This report examined the effects of road salt in relation to growth and germination in the Brassica rapa, a common turnup flower. The initial questions considered if the salt would actually affect the growth. There were four groups of plants which were collected. The groups included a control (0.00% sodium chloride), 0.25% sodium chloride, 1.00% sodium chloride, and 4.00% sodium chloride. Data was collected from the length of the plant, color, length of nodes and number of flowers. The experiment showed that sodium chloride (road salt) does in fact affect growth and germination in plants.
[...] The leaves tend to be a cornucopia shades of green ranging from light to medium, which are either hairy or briskly and about forty to fifty centimeters long (Purdue University, Department of Horticulture). Purdue Lacina 3 University points out the toxicity of the Brassica rapa is occasionally suspected of poisoning bovines, sheep, and pigs but other sources such as www.prota.org specifies the toxicity is confused whether if it does endanger animals, yet several reports have been proposed. The Brassica rapa is a crop of many uses, the most important and well known is human consumption. [...]
[...] Results Finding the effects of salt on germination and growth of plants took twenty-two days of research. Each collection day the height, length of the leaf, color, length of the node, number of buds, and the number of the flowers were taken into account. Based on the original hypothesis stating that the of sodium chloride will not develop well and will most likely die was correct. Throughout the procedures the control group displayed the maximum of values each section should experience. [...]
[...] Although the original experiment was destroyed after collection day six, data from other groups proved the hypothesis to be correct and carried on where the plants left off. The first half of the experiment started off very well and showed to prove the hypothesis for the rest of the collection days. According to figure the control group displayed the maximum height any of the groups will achieve. Collection Lacina 8 began on the fourth day after adding the specific water to sodium chloride ratio every other day. [...]
