    Macroelement (N, P, K) contents of Romulea columnae Seb. and Mauri Subsp. columnae during vegetative and generative growth phases
    (Academic Journals Inc., 2007) Kök T.; Bilgin A.; Özdemir C.; Kutbay H.G.; Keskin M.
    Romulea columnae Seb. and Mauri subsp. columnae is a geophytic plant belonging to Iridaceae. In this study nitrogen (N), phosphorus (P) and potassium (K) analysis were carried out during vegetative and generative growth periods. It has been found that above ground parts of plant have higher macroelement concentrations as compared to below ground parts during vegetative growth period. However, below ground parts have higher macroelement concentrations during generative growth phase due merely to top senescence. In addition to this there were significant and mostiy negative conelations between plant and soil macroelement concentrations. © 2007 Academic Journals Inc.

    Structural investigation of the glandular trichomes of Salvia argentea
    (2010) Baran P.; Özdemir C.; Aktaş K.
    The morphology, anatomy and distribution of glandular trichomes on the aerial organs of Salvia argentea L. has been investigated. Two morphologically distinct types of glandular trichomes were determined. Capitate glandular trichomes forming a base 1-7 celled, a stalk 1-5 celled or no stalk and a head uni- or bicellular had various types. In capitate trichomes, the neck cell that has an important role especially for xeroformic plants, acting to prevent the backflow of secreted substance through the apoplast has been distinctively observed in the investigated species. The capitate trichomes were present abundantly on all aerial organs of S. argentea. Peltate glandular trichomes had a large secretory head forming 1-5, 8 central and 8-10, 12, 14 peripheral cells. Peltate trichomes are present on all aerial organs, except petiole, being the most abundant on calyx and corolla.
