Fig. 2From: Nutrient solutions for Arabidopsis thaliana: a study on nutrient solution composition in hydroponics systemsThe mean relative growth rate (RGR) of Arabidopsis rosettes (circles) during 4 weeks grown in different nutrient solutions (Exp. 1). Error bar represents the standard deviation of the mean (n = 6). RGR data were fitted using either a constant relative growth rate (black dashed line, Eq. 1 with 95% confidence interval in grey) or a linearly declining relative growth rate (solid green line, Eq. 2 with confidence interval in green)Back to article page
