Figure 7From: Improved methodology for assaying brassinosteroids in plant tissues using magnetic hydrophilic material for both extraction and derivatizationEffect of plant tissue amount on BR assay. Effect of the plant amount on the extraction efficiencies (black line) and mass response (blue line) (n = 3) (A). Investigation of the minimal amount of plant tissue (n = 3) (B). O. sativa L shoot was analyzed.Back to article page
