Table I. T6P content in growing potato tubers.
Samples were taken from growing tubers and immediately frozen in liquid nitrogen before T6P levels were determined using HPLC-MS/MS. Values represent means ± sd of four to seven individual tubers and leaves from five individual plants per plant line. * Significant difference (P < 0.05); ** P < 0.001 according to t test (I) compared with the wild-type control.
