Abstract
The growth of Thespesia populnea (L.) Soland. ex Correa, was studied in soils collected from Khan Towel, Tanveer Garment, One
Tech Rubber and One Tech Ply Board factories in the vicinity of Korangi and Landhi industrial areas. A numbers of growth
parameters were higher in almost all of the industrial locations soils mainly of One Tech Ply Board factory soil, Tanveer Garment,
Khan Towel and One Tech Rubber factory soils, respectively as compared to Karachi University soil. One Tech Ply Board factory soil
fairly increased several growth properties like plant height, number of leaves, plant cover, shoot length, leaf area, root, shoot, leaf and
total plant dry weights, specific leaf area and leaf area ratio whereas root, seedling length and root/shoot ratio were substantially
enhanced in the treatment of Tanveer Garment factory soil. One Tech Rubber and Khan Towel factories soils raised a large number of
growth parameters such as plant height, leaves number, plant cover, root, shoot and seedling length, leaf area, root, shoot, leaf and
total plant dry weights, root/shoot ratio and specific leaf area as compared to University soil.
