"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......
