Interaction Maps on Red Spinach Morphological Features.  The morphological data for 2-compound combinations were used to generate interaction maps that describe the compound interactions at different concentration ratios (N = 2-6). The unit for SWE is % v/v. Ethylenediaminetetraacetic Acid Iron (III) (EDTA-Fe), 6-Benzylaminopurine (6-BAP), Humic Acid (HA), and Seaweed Extract (SWE).
