Screening and Evaluating Responses to NaCl in Cotton G. Hirsutum

Concerns are increasing in regards to the negative infliction of saline sediment depositions and saline water that limit irrigation practices and crop efficiency. The effect of concentrates, in particular NaCl, found in the water supply and soil in inhibiting plants from maintaining their normal physiological activities is a rising problem. The primary objective of this study was to assess the utility of the hydroponic system as screening methodology for breeding saline tolerant cultivars. A secondary objective was to screen and evaluate the effects of salinity over time and at different dose concentrations on root biomass production; and to determine if differences in root biomass among genotypes can be attributed to salinity tolerance.
