摘要: Abstract Plants of Brassica campestris L. var. G-S20 were treated with cement dust, at rates 3 (B 1 ), 5 2 ) and 7 gm −2 day −1 for 90 days. Treated plants showed a consistent reduction in growth, photosynthetic pigments, yield oil content over control plants. The overall phytomass was significantly decreased, the maximum being 64.8% B plants, followed by (55.3%) (43.69%) 60 effect on also greatest where it decreased 6.13%.
