An experiment was designed to study the interaction effects of Pb(NO3)2 and salinity on the growth of eggplant . Tow seedling of each plant were transported to each pot , NaCl was added at ( 0 , 250 , 500 , 750 ppm ) on 10 /1/2011 and on 10/2/2011 , while Pb(NO3)2 was added at ( 0 , 50 , 150 mg Pb / Kg soil as Pb(NO3)2 . After 90 days the plants were harvested. Results showed that plant performance was significantly reduced with increasing concentration of both NaCl and Pb
Contamination. Plant parameters (plant height cm, root length cm, leave FW and DW gm / plant, root FW and DW gm / plant, shoot FW and DW gm / plant, leaves No. and branches No.) were affected significantly by salinity and Pb . There was a significant interaction between salinity and Pb contamination. |
