Developmental changes in adenine nucleotide levels and energy state in growing rape seeds. At different time points between 15 and 45 DAF, siliques were rapidly frozen in liquid N₂, and the seeds were separated from the silique wall under liquid N₂ to analyze nucleotide levels: A, ATP; B, ADP; and C, ATP to ADP ratio. Data are means ± se (n = 3 different plants). Samples were taken from the same plants as in the experiment of Figure 1. Error bars are not shown when they are smaller than the symbol.
