Figure 3 : Comparison of the glucosylglycerol (GG) amount in leaf extracts of different transgenic potato clones by GC.

(A) GG amounts in young leaves (3rd leave from the top of 4 weeks old plants grown under standard conditions); (B) GG amounts in leaves of different ages (3 - 9, youngest to oldest leaf, leaves were counted from the top). Mean values ±SD (vertical bars) of one representative greenhouse experiment are shown. Statistical significant differences between GG contents of clone Alba-AF1and the other two clones are marked by asterisk.
