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
[...] 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. [...]
[...] The University of Liverpool claims although this is a world-wide issue, it is less of an issue in North and Central Asia, South America, and in Australia. The University of Wyoming's Department of Plant, Soil, and Insect Sciences / College of Agriculture also chimes in with this issue. Like the other sources, the university suggests the excessive accumulation of soluble salts (also known as soil salinity) does indeed suppress plant growth. These salt-affected areas are most common in arid and semi-arid regions (University of Wyoming). [...]
[...] These tolerances are based on climate, soil, growing conditions, cultural practices, and a variety of other attributes (University of Wyoming). Salt-tolerant plants are more adjustable to osmotic effects of high sodium chloride conditions where as salt-sensitive plants are not. The salt-tolerant plants will absorb as much water as possible from saline soils where the salt-sensitive plants are limited to adjust and are injured at small concentrations of salt. In the case of the Brassica rapa study, the classification which governs the acts of sodium chloride is moderately sensitive. [...]
[...] The apex of the 1.00 group reached at 1.00 mm, and lowest at around .75mm. The average for this specific day was at 1.2 mm. On the other hand, out of the five plants originally planted in the group, only one displayed leaves. The leaf of this plant was only 0.5 mm high, which makes the average a mere 0.5 mm. The hypothesis also stated that the number of buds would also suffer in the 4.00 and 1.00 group due to the excessive amount of sodium chloride added within each day. [...]
