aTreatment A (0.2 M mannitol), B (0.2M sorbitol), C (0.2M mannitol + 0.2M sorbitol), control (no osmoticum)

bData was measured 6 (PPT) and 8 weeks (LUC/GUS assay) after transformation by counting the number of positive clumps

cData was measured 12 weeks after transformation by counting the number of tissues with browning and somatic embryos, respectively.

dMeans followed by different letters are significantly different at the P=0.05 level.
