Embryological Features of Laburnum anagyroides Medik.

Glycopolymer compounds make up structural and functional basis of cells and tissues of a living organism. The necessity of anatomical-lectinohistochemical examination of the parotid gland in early prenatal period of ontogenesis is substantiated, as the evidences concerning its topography are fragmentary and not systematized, and certain aspects of its ontogenesis are disputable. 35 human embryos and pre-fetuses aged from 21 days to 12 weeks of intrauterine development were examined. Glycopolymers were found by means of treatment of serial sections with lectins conjugated with horseradish peroxidase. The dynamics of prenatal morphogenesis of the embryos and pre-fetuses of the 4th-12th week of embryogenesis expression of glycopolymers – lectinreceptors on the surface of cells, in the cytoplasm and on the basal membrane of the parotid gland epithelial germs and the human oral cavity with its derivatives by re-distribution of glycopolymers are similar, which can be the evidence of ectodermal source of the parotid gland epithelial germ. Immersion of the epithelial cells of the buccal-alveolar pockets into the lower adjacent mesenchyme with the formation of primary parotid gland germs in embryos with 11,0-12,5 mm of PCL and their transformation into the epithelial taeniae is associated with accumulation of sialic glycopolymers (N-acetyl neuraminic acid), N-acetyl-D-glucosamine – specific to Wheat germ agglutinin (WGA) and Sambucus nigra agglutinin (SNA); N-acetyl-2-desoxy-2-amino-D-glucopyranose, screened by sialic acid of ß-D-galactose and α-L-fucose – specific to Helix pomatia (edible snail) agglutinin (HPA), Rhizoctonia solani agglutinin (RCA) and Laburnum anagyroides (Golden Rain shrub) agglutinin (LABA) respectively. These glycopolymers are present during the first 12 weeks both on the cytolemma of the cells of the parotid gland epithelial germ and in their cytoplasm. The results of lectin-histochemical examination of the early prenatal ontogenesis of the parotid gland can form the basis for the work of laboratories dealing with screening of morphological material in order to assess the degree of maturation and prognosis of fetus viability and diagnostics of deviations from normal development.

Abstract A study on the flowering biology and pollen production of the common laburnum (Laburnum anagyroides Med.) was conducted under the conditions of Lublin during the period 2004 - 2006. The flowering of this species began in the second 10-day period of May and lasted for 2.5 - 4 weeks. The flowers of common laburnum are borne in showy golden-yellow pendulous racemes. They develop successively, starting from the base and moving to the tip of an inflorescence. During the growing season, one shrub produces 800 to 3200 racemes, with 14 to 35 flowers in a single raceme. On average, the flowering duration for a raceme was 12.8 days and 8.7 days for a single flower. Throughout the study years, the shrubs proved to be most attractive in the third 10-day period of May when they reached full bloom. The average weight of pollen produced was 6.08 mg per 10 flowers of Laburnum anagyroides, 14.02 mg per raceme, and 26.0 g per shrub. Pollen grains reached average dimensions of 24.01 μm × 24.26 μm.

[14C]Cadaverine was applied to leaves of Lupinus polyphyllus, L. albas, L. angustifolius, L. perennis, L. mutabilis, L. pubescens, and L. hartwegii and it was preferentially incorporated into lupanine. In Lupinus arboreus sparteine was the main labelled alkaloid, in L. hispanicus it was lupinine. A pulse chase experiment with L. angustifolius and L. arboreus showed that the incorporation of cadaverine into lupanine and sparteine was transient with a maximum between 8 and 20 h. Only leaflets and chlorophyllous petioles showed active alkaloid biosynthesis, whereas no incorporation of cadaverine into lupanine was observed in roots. Using in vitro organ cultures of Lupinus polyphyllus, L. succulentus, L. subcarnosus, Cytisus scoparius and Laburnum anagyroides the inactivity of roots was confirmed. Therefore, the green aerial parts are the major site of alkaloid biosynthesis in lupins and in other legumes.

Vitro Effect

The study focuses on in vitro effect of aqueous tinctures of 48 species of herbaceous, shrub and tree plants on the first-third stage larvae of Strongyloides papillosus (Wedl, 1856) and third-stage larvae of Haemonchus contortus (Rudolphi, 1803) Cobb, 1898. The highest level of the effect was exerted by 3% aqueous tinctures of Wisteria sinensis (Sims) DC., Ailanthus altissima (Mill.) Swingle, Laburnum anagyroides Medik., Quercus petraea subsp. iberica (Steven ex M. Bieb.) Krassiln., Ginkgo biloba L., Colchicum autumnale L., Aristolochia manshuriensis Kom., Celastrus scandens L., Securigera varia (L.) Lassen, Magnolia kobus DC. Over 90% of the first and second non-invasive stage larvae of S. papillosus died at contact with these tinctures. The lowest parameters of LD50 were seen for L. anagyroides, Juniperus sabina L., C. scandens, M. kobus, A. manshuriensis, Wisteria sinensis (Sims) DC. and Securigera varia (L.) Lassen. Invasive larvae of S. papillosus and H. contortus were resistant to the effect of all the 48 surveyed species of plants. Third-stage larvae of H. contortus remained vital when exposed for 24 h to all the studied concentrations up to 3% aqueous tincture of plants. The results of the experiments and also the analysis of the literature indicate the necessity to continue the survey on nematocidial activity of aqueous tinctures and alcveshol extracts of plants.
