Effects of plant type and salinity on diameter of brown and black seeds for different nutrient availabilities. (a, b) Low nutrient, (c, d) Moderate nutrient, (e, f) High nutrient. N: Nutrient; BrP: Plant grown from brown seed; BlP: Plant grown from black seed. F-values are given when significance levels are reached (S: salinity; PT: plant type; * P < 0.05, ** P < 0.01, *** P < 0.001). Bars with the same uppercase letters are not significantly different at P < 0.05 according to the Tukey’s test.
