Effects of plant type and salinity on final germination percentages of brown seed cultivated from different gradients of nutrients and salt concentrations . (a, b, c) Low nutrient, (d, e, f) Moderate nutrient, (g, h, i) High nutrient. N: Nutrient; BrP: Plant grown from brown seed; BlP: Plant grown from black seed. W-values are given when significance levels are reached (S: salinity; * P < 0.05, *** P < 0.001). Over-lapping values are represented split white-black data points.
