The contents of total polysaccharide among callus and different organ samples. (A) Polysaccharides content in different samples. The X axis is the sample name and the Y axis is the content (mg/g DW), and DW means dried weight. Bars with different letters within same histogram, represent significant difference at p ≤ 0.01. (B) Standard curve, R2 = 0.9991. The X axis is the standard concentration (μg/mL), and the Y axis is the absorbance value.
