Genetic diversity among four genotypes from Hibiscus rosasinensis in relation to drought stress

The effect of drought stress on growth and water relations of four Hibiscus genotypes was investigated. Drought stress significantly retarded vegetative growth as analyzed by plant height, stem diameter, leaf area, fresh and dry weight. The osmotic potential (ys) values decreased with increasing drought time, and the decrease was more pronounced in Fantasia followed by Jay´s orange. Osmotic adjustment (O.A.)...
