Abstract: Cadmium (Cd) is one of the most toxic elements to plants, so Cd-tolerant trees should be used in reforestation or remediation systems. In this study the effects of Cd on seed germination and early seedling growth were evaluated in Schinus molle plants. Seeds of S. molle were treated with Cd at concentrations of 0 (control), 0.01, 0.02, 0.05, and 0.125 mM using Cd(NO3)2. Seed germination parameters and seedling growth traits were evaluated 33 days after the experiment started. Seeds and roots were sampled for anatomical evaluation and processed with plant microtechniques. No effects of Cd were found on the germination percentage of S. molle seeds. However, seedlings’ shoot and root fresh masses and lengths increased with Cd treatment. Cadmium increased root cortex and endodermis thickness and reduced the percentage of vascular tissues in seedlings. Schinus molle seeds and seedlings thus showed tolerance to Cd related to anatomical adaptations.
