From: Chitosan nanoparticles improve physiological and biochemical responses of Salvia abrotanoides (Kar.) under drought stress

Fig. 3

Effects of different concentration of chitosan nanoparticles (CNPs) (30, 60 and 90 ppm) and drought stress levels (30, 50, and 100% FC) on carotenoid content in leaves of S. abrotanoides. Values are means ± SD (n = 4). According to Duncan’s Multiple Range Test, different bar letters indicate significant differences among treatments (P ≤ 0.05)
