Flavonoids are a group of secondary metabolites found in most families. They are known to have important physiological functions in plants by protecting them against biotic stresses. Liquid chromatography (HPLC) was used to determine the flavonoid profiles, especially apigenin glycosides, their total concentration, as well as changes in the amount of six flavones found in the aerial parts of al...

Alfalfa in dry stress conditions cannot grow optimally. Drought inhibits growth and reduces alfalfa production many cultivation systems. Plants breeding with gamma-ray irradiation vitro selection using PEG found somaclonal variants adapted to well drought conditions. This study aims determine the type of mutation best morphology mutants resulting from gamma were sub-cultured vitro. cultured med...

The present study was aimed to determine the effect of V2, VR10 and VR1 experimental biostimulants application on yield related main traits (plant height stems number per m2) forage productivity Prista 4 alfalfa variety. carried out in Experimental field at Institute Agriculture Seed Science "Obraztsov chiflik" - Ruse, from 2019 2021. were foliarly applied two times each regrowth. There found p...

BACKGROUND Molecular structures in feed protein influence its digestive behavior, availability and utilization. From a nutritive point of view, stage of maturity and cutting time are important factors affecting nutrient profiles and availability of alfalfa (Medicago sativa L.) hay in ruminants. The objectives of this study were to determine protein molecular structures by Fourier transform infr...

Little is known how the deep root systems of perennial crops contribute to deeper and better resource use when intercropped with annuals in arable fields. Therefore, we aimed at measuring capacity deep-rooted perennials, alfalfa ( Medicago sativa L.) curly dock Rumex crispus access nutrients located under neighboring 1.0 2.5 m soil depth. Alfalfa were able tracer sources 15 N Cs) placed a dista...
