Comparison of agroinfiltration and particle bombardment methods on transformation in onion epidermis.

Note: three samples per unit of infiltration components were investigated for ten 2 mm2 epidermal areas. The efficiency value represents the mean of transformation efficiencies of thirty replicates of 2 mm2 epidermal areas from three samples (the percentage of positive cells in total cells per unit area) in the part of transformation efficiency, and the standard errors were calculated by using Excel.
