Interrelationship between T6P and sugars measured in the different treatments. A, T6P and Suc (0.5% [w/v] Suc, solid line, R  ² = 0.84, SEE = 0.56, P < 0.011; 10°C, dashed line, R  ² = 0.99, SEE = 0.35, P < 0.0001; No N, dotted line, R  ² = 0.90, SEE = 0.70, P < 0.0041). B, T6P and Glc (0.5% [w/v] Suc, solid line, R  ² = 0.68, SEE = 0.79, P < 0.045; 10°C, dashed line, R  ² = 0.80, SEE = 1.04, P < 0.016; No N, dotted line, R  ² = 0.74, SEE = 0.94, P < 0.028). C, T6P and Fru (0.5% [w/v] Suc, solid line, R  ² = 0.73, SEE = 0.72, P < 0.029; 10°C, dashed line, R  ² = 0.82, SEE = 1.00, P < 0.013; No N, dotted line, R  ² = 0.72, SEE = 0.96, P < 0.032). The data are means of three independent samples.
