Specific features of the biochemical composition of life forms of black medic (<i>Medicago lupulina</i> L.)

BACKGROUND: Black medic is used as a pasture, cover, siderate, anti-erosion culture for fixing embankments along roads, on mining dumps and phytoremediation. Mono-, bi- polycarpic forms are distinguished within the species, differing in number of fruitions during plant life cycle. The presence polymorphism morphological features ontogenesis suggests differences biochemical parameters selected groups.
 AIM: aim study was to various black medic.
 MATERIALS AND METHODS: material 20 accessions origins from groups mono-, plants VIR collection. For study, freshly harvested green mass used. assessment carried out according following parameters: content dry matter, protein, sugars, ascorbic acid, total acidity, chlorophylls, carotenoids, carotenes, -carotene, anthocyanins. Statistical processing results included calculation main variation, analysis variance discriminant analysis.
 RESULTS: nutritional value characterized by crude protein sugars. range variability ranged 11,94 19,69 mg / 100 g raw sugars 0,44 2,67%. Differences sugar different were revealed. acid highest five varieties group presented comparison with wild-growing monocarpic Bereginya variety. Monocarpics anthocyanin (19,5 1,41 g); no significant found other pigments.
 CONCLUSIONS: in-depth collection genetic resources demonstrate high biologically active substances will significantly improve choice initial selection forage usage.
