The studies on Asphodelus albus Miller flowers were conducted in the Botanical Garden of the UMCS in Lublin in the years 2004-2005. The flower nectaries location was determined in a stereoscopic microscope. The nectaring abundance was studied with a pipette method described by Jabłoński and Szklanowska (1979), while pollen efficiency determined after Warakomska's ether method (1972). Pollen viability...
Badano cechy morfologiczne i anatomiczne oraz związane z ultrastrukturą komórek nektarników Achillea millefolium z rodziny Asteraceae. Obecność nektarników stwierdzono tylko w kwiatach rurkowatych u podstawy szyjki słupka. Zbadano mikromorfologię nektarników w SEM, przeprowadzono obserwacje struktury w mikroskopie świetlnym i transmisyjnym elektronowym. Określono liczbę warstw budujących gruczoł,...
The structure of nectaries in the flowers of Myosotis sylvatica Hoffm. was studied by light microscopy, scanning electron microscopy and transmission electron microscopy. A nectariferous gland of irregular disc shape surrounds the bottom of the four-lobed ovary. From the upper side, both the nectary and the ovary are protected by ligulate folds of a widening corolla tube with epidermis outgrowths...
