Physiological age 1: rosette stage; physiological age 2: main stem during plant bolting; physiological age 3: ramification; physiological age 4: flowering and pod growth on the main stem; physiological age 5: flowering and pod growth on the ramification. Photosynthetic surfaces during physiological ages 1–3: leaves; during physiological ages 4 and 5: pod envelopes. Internodes during physiological ages 1–3: internodes of the stem; during physiological ages 4 and 5: internodes of the racemes. a and b are parameters of the beta-function (see Materials and Methods).
