Fenugreey Research Paper
"To examine the effects of salinty on fenugreek seeds."
INTRODUCTION
Since the arrival and settlement of European farmers two hundred years ago, dryland and irrigated-land salinity have become problematic for the Australian environment, despite the fact much of our natural landscape is naturally saline. The response of plants to salinity has been explained as a two-phase growth response. The first phase of growth reduction is characterised by osmotic stress due to salts in the outside solution, while the second phase develops after salt build-up in transpiring leaves and shows clear genotypic variation (Fortmeier and Schubert, 1995).
Salinity impairs plant growth through osmotic effects, specific ion toxicities, and induced nutrient deficiencies (Wyn Jones, 1981). High salt stress has been found to interrupt homeostasis in regard to water potential and ion distribution which can lead to molecular damage, growth and arrest. It is for this reason, environmentalists and environmental organisations are so concerned about the consequences of salinity on the Australian environment …show more content…
A reason for this could be the absorption of each of the seeds used in the experiment. Each seed might have a different reaction to salinity due to its individual root absorption rate. This is significant as some might take in more NaCl during the twenty-four hour soaking period than others. Despite this, the results show a trend in stunted growth with increasing salinity concentrations, demonstrated by the larger p values in each of the t-tests for control versus high concentration, as opposed to the t-tests for control versus low concentration. Another trend which occurred is the more successful the seed germination for the control, the smaller the significance in p
