Fresh aboveground biomass productivity. (A) Productivity was measured for nontransgenic hybrid plants and nontransgenic TN 90 plants in a field experiment over two years with three measurements per year. (B) A greenhouse study was conducted during one year with two measurements of the hybrid GFP line, the transgenic parental lines of the aforementioned hybrid, and a nontransgenic hybrid line. Mean separation is by Fishers LSD and bars marked by the same letter are not significantly different (p < 0.05). Error bars are the standard error of the means.
