Fig. 5From: Assessment of drought tolerance of 49 switchgrass (Panicum virgatum) genotypes using physiological and morphological parametersThe levels of abscisic acid (ABA), spermine, trehalose, and fructose in five best drought-tolerant genotypes and the five most drought-sensitive genotypes under well-watered conditions (control, solid bar) and drought stress (open bar) after 30 days of treatment. The values are the means of six replicates (n = 6). The bar represents LSD (0.05) for levels of abscisic acid (ABA), spermine, trehalose, and fructoseBack to article page
