Leaf tissue of alfalfa (Medicago sativa L.) was found to contain prolinebetaine, pipecolatebetaine, hydroxyprolinebetaine, and glycinebetaine. As n-butyl esters, these chemical species exhibit molecular cations at mass/charge ratio (m/z) 200, 214, 216, and 174, respectively, when analyzed by fast atom bombardment mass spectrometry. The underivatized betaines exhibit protonated molecular ions at...
Adhesion sites on grass roots for Klebsiella strains carrying type 3 or type 1 fimbriae or both were determined. Adhesion of the strains to the roots of Poa pratensis and Festuca rubra was highly localized; the bacteria adhered strongly to root hairs and with a markedly lower efficiency to the surface of the zone of elongation and to the root cap mucilage. No adhesion to the epidermal cells bet...
Introduction. Geroprotectors are biologically active substances that inhibit the aging process. Many plant species natural geroprotectors. For instance, Thymus vulgaris and Trifolium pratense callus cultures with strong geroprotective properties.
 Study objects methods. The present research featured T. grown in vitro on various nutrient media. Their extracts were obtained by aqueous-alcoho...
Multispecies swards, comprised of different plant functional groups have comparable production potential to high N input L. perenne swards at reduced when legumes are included. However, information on the appropriate management multispecies is limited. The effect differing practices herbage dry-matter (DM) and botanical composition sward types was investigated using a 3 × 2 factorial design plo...
