Behavior of BY-2 protoplasts/cells during culture. Four-day-old BY-2 cells were converted to protoplasts and cultured in either 2,4-D medium A or BA-NAA medium B, and the changes in the mitotic index (●) and cell length (○) were followed during the culture. Each data point for mitotic index was determined by counting more than 1,000 cells/protoplasts. Each point for the length of cells/protoplasts represents the average value from 30 (for 2,4-D medium) or 60 (for BA-NAA medium) cells/protoplasts. Vertical bars represent standard errors
