The effects of cadmium, inoculation with either Bradyrhizobium or VA- mycorrhizae and kinetin application as well as their interactions with cadmium on growth, anatomical structure of both leaves and stems as well as yield and its components in soybean plants were investigated. Cadmium treatment decreased plant height, number of branches, leaf area and dry weight of shoot/plant. In addition, photosynthetic pigments contents in the leaves and carbohydrates concentrations in the shoots. pod number/plant. seed weight (g)/plant and 100 seed weight (g) were also decreased. Calcium concentration in the shoot system as well as N, protein, P and K percent in the seeds were decreased, while, Cd concentration in the shoots was increased. Inoculation with either Bradyrhizobium or VA-mycorrhizae and kinetin application increased all investigated parameters with the exception of Cd content in shoots in Cd-polluted soil. It is interesting to mention that these treatments alleviated the adverse effects of cadmium treatment and improved the plant growth. However, kinetin application was the most effective treatment in this respect compared with other treatments. Regarding the anatomical structure of plant, cadmium treatment decreased stem diameter and thickness of cortex, xylem, phloem and pith tissues thickness. Metaxylem vessels diameter was also decreased as well as thickness of either leaflet blade or mesophyll tissue thickness due to reducing thickness both palisade and spongy tissues thickness. The size of the midvein vascular bundle was also decreased as indicated by its dimension.
