From: A nondestructive method to estimate the chlorophyll content of Arabidopsis seedlings
Correlation of the chlorophyll content estimated by RGB value and chemical extraction. a, b Comparison of extracted chlorophyll calculated by the Lichthenther (a) and Arnon (b) methods to chlorophyll content estimated by RGB value of Arabidopsis seedlings grown in agar plates under different C/N treatment (n = 234, four independent experiment). c, d Chlorophyll content estimated by RGB value and chemical extraction in soil-grown-plant using the defaulted coefficients (c) versus the refitted coefficients (d), respectively (n = 15)
