Effect of salinity stress on carbohydrate metabolism in cryptocoryne elliptica cultures

Abstract

Salt condition could disturb water availability in plants which causes growth disturbance and also death. The plant regulates the stress by altering sugar content at metabolism level to survive the stress. This study was carried-out to determine the effects of different NaC1 concentrations - 100mM and 200mM/L - on carbohydrate metabolism in aquatic plant, Cryptocoryne elliptica cultures, as a model plant, for 35 days. The aquatic habitats represent stressful environments which are characterized for example by low carbon availability, uncertained availability of nutrient and shaded conditions induce plants to adapt with the environment on its fully potentials. Limited studies of aquatic plants also encouraged the study to be done. The salinity treatments were also carried-out in two different medium conditions: sucrose-contained- and sucrose-free medium. In this study, the accumulation of biomass, starch content and reducing sugar content were determined.
