Description
Summary:Seedling emergence and plant growth of two canola varieties (Brassica napus L.) were investigated in response to soil salinity under growth chamber conditions. HCN92, a genetically transformed variety tolerant to the broad spectrum herbicide glufosinate-ammonium, and variety Legend were grown in five field-collected soils with salinities between 0.8 and 11.5 dS m −1 . Salinity treatments significantly reduced total seedling emergence and emergence rate, and also caused decreased leaf area, shoot and root biomass, and evapotranspiration in both canola varieties. Vegetative growth of the genetically transformed variety, HCN92 was essentially equivalent to that of variety Legend at all salinity levels. Key words: Emergence, HCN92 canola, Legend canola, plant growth, salt tolerance
