In this study we investigated the effect of maturity stage on chemical composition, in vitro dry matter digestibility (IVD) and volume of gas produced at 24 h (G24) of forages from Avena sativa L. (oats), Trifolium alexandrinum (berseem), Vicia sativa L. (vetch), Avena sativa-Vicia sativa (OV) and Avena sativaTrifolium alexandrinum (OB) mixtures collected at progressive morphological stages (S1...

Three new chalcanol glucosides have been isolated from the seeds of Trifolium alexandrinum, of which the first two are alpha'-chalcanol-alpha, beta-epoxides and the third one is an alpha, beta-dihydroxy-alpha'-chalcanol. The structures of the isolated compounds were verified by means of MS and 2D NMR spectral analyses.

The release and persistence of toxic heavy metals into the natural environment is a serious concern especially in urban areas. The problem of heavy metal pollution is gaining momentum from year to year as more and more amounts of heavy metals are extracted from their ores and released into the environmental segments (water, air and soil) during processing or afterwards. Heavy metals are essenti...

1. To study the potential for complementarity in nitrogen acquisition from different soil depths, we injected an isotope tracer ( 15 NH 4 Cl) at 5 and 20 cm depths in plant communities containing Achillea millefolium L. and Festuca ovina L. or Phleum pratense L. and Trifolium pratense L. in monocultures and two-species mixtures. 2. In monoculture, Festuca and Phleum took up tracer at 5 and 20 c...

Egyptian clover (Trifolium alexandrinum) is the main and oldest cultivated winter forage leguminous crop in Egypt. It occupies about one third of area with average 1.63 million Feddan (Feddan= 4200 m2 ). With an estimated productivity 42.03 tons green fodder [7]. In last years, mower conditioner machine used Egypt to cutting crops. The mean objectives current research were evaluated new wear bl...

Some plant species belonging to Trifolium L. genus are a source of isoflavones considered to exert phytoestrogenic activities. The aim of the present study was to examine the effects of standardized extract obtained from aerial parts of Trifolium medium L., in comparison with the extract of Trifolium pratense L., on the development of estrogen deficiency-induced osteoporosis in rats. Both Trifo...

Tricolorin A acts as pre- and post-emergence plant growth inhibitor. In pre-emergence it displays broad-spectrum weed control, inhibiting germination of both monocotyledonous (Lolium mutliflorum and Triticum vulgare) and dicotyledonous (Physalis ixocarpa and Trifolium alexandrinum) seeds, being the dicotyledonous seeds the most inhibited. Tricolorin A also inhibited seedling growth, and seed r...
