| Abstract | ||
| Polluted soil with lead at 200 ppm decreased plant growth of mungbean plants, expressed by length of shoot system. its dry weight. number of branches and leat area (cmzl plant as well as photosynthetic pigment concentrations in the leaves in both seasons. While, lead concentrations in both root and shoot systems were increased Lead was more concentrated in the root than shoot system. Thickness of leaflet blade at mldvein. mesophyll tissue thickness. size of the midvein vascular bundle, xylem and phloem tissues thickness as well as metaxylem vessel diameter were also decreased. Yeild and its components represented by pods number! plant. seed weight! plant and 100 seed weight as well as the percentages of total soluble carbohydrate. protein. N. P and K in the seeds were atso decreased. 0n the other hand. treatments with phosphorus. yeast and VA- mycorrhizae and their interactions increased all the above mentioned parameters in both non- polluted and polluted soils. Treatment with yeast alone as well as the interaction between P and VA-mycorrhizae were the most effective in this respect. These treatments are recommended not only for improving plant growth and yield of mungbean plant but also for recovery the adverse effects of lead pollution.
