Notes:
Vicia sativa L.) at seven maturity stages defined as progressively higher dry matter (DM) content in the seed (200–250, 250–300, 350–450, 450–550, 600–700, 700–800, and 〉800 g DM kg-1 seed). Concentration of assimilates in plant parts changed over the whole seed-filling period. During the phase of rapid seed growth (from 200–250 to 450–550 g DM kg-1 seed), assimilation was dominant for starch (net gain of 1086 kg ha-1), redistribution for TSS (net loss of 104 kg ha-1), and both process were operative in total N (net gain of 193 kg ha-1). During the ripening phase (from 450–550 to 〉800 g DM kg-1 seed), most chemical components except ADL showed a net loss. Maximum total accumulation for most mobile fractions except TSS was reached at the 450 to 550 g DM kg-1 seed maturity stage. Harvesting common vetch at this stage would represent maximum efficiency for total N and starch. Concentrations of nonstructural chemical components had a nonlinear trend while concentration of fiber fractions and lignin in vegetative structures showed a linear increasing trend over the seed filling phase of common vetch.
