Abstract: A pot experiment was conducted to study the effects of different zinc treatments on growth, yield, and nutrient uptake and enrichment characteristics of zinc in above-ground organs of rapeseed (B. napus cv. ‘Qinyou 9’). Comparing with the control, low zinc level in soil stimulated the rape growth to some extent, but had less effect on the plant biomass, photosynthetic rate yield and main mineral element contents. With the further increase of zinc level in soil, the plant biomass, photosynthetic rate, yield, main mineral element contents, height and main inflorescence length decreased gradually, while number of first branch was less affected. There were significant differences in the enrichment characteristics of zinc in above-ground organs of rapeseed, following an order of stem>seeds.

Key words: zinc, rapeseed, enrichment characteristics
