Shorttitle:A pot culture experiment was conducted in the glasshouse at Holetta Agricultural Research Centre, Ethiopia. The aim of the trail was to study the impact of Cr on seed germination and growth of Eucalyptus camaldulensis, Millittia ferruginea, and Ricinus communis and to see storage of metal use of phytoremediation. Cr2 (SO4)3.6H2O and (K2Cr2O7) at four concentration levels (0, 10,100, 1000 ppm) were used as treatment. The growing media was prepared by mixing 3 forest soil, 3 local soil, 1 manure, and 1 sand . Before sowing, the media were filled into polythene bags and pots were laidout in completely randomized design with three replications, germination was not significantly different for the two Cr species however it was differing significantly for different concentration of Cr and tree species. However, height and root collar diameter were significantly differed for the treatments at (P?0.05). For Cr extraction plant parts were separately collected, oven dried, ...
