From: Effect of hemoglobin on the growth and Cd accumulation of pea plants (Pisum sativum L.)
Effect of hemoglobin-to-cadmium (Cd) molar ratios in the Cd-contaminated soil [6.0 ± 0.61 mg Cd (kg soil)−1] on (A) the Cd accumulation in unit dry mass of Pisum sativum, (B) Total mass of the Cd accumulated in one pot, and (C) Fe accumulation in unit dry mass of P. sativum. The different small letters indicate a statistically significant difference (95% confidence level) based on the Tukey’s test results
