In this study, cytochemical staining methods were used to follow the cytochemical modifications of microspore cytoplasm and sporoderm in Campsis radicans (L.) Seem. from tetrad stage to mature pollen. Flower buds were collected at different stages of development, and the anthers were fixed and embedded in Araldite. To make cytochemical observations under(More)
In this study, polysaccharide and RNA contents of anthers were investigated on different phases of sporogenesis by using light microscopy techniques from histological and cytological point of view in Leucojum aestivum. Paraffin and semi-thin sections of anthers were stained with toluidine blue and PAS. Anthers were tetrasporangiate. The wall of the anther(More)
In this study, distribution of polysaccharides, lipids, and proteins in the developing anthers of Campsis radicans (L.) Seem. was examined from sporogenous cell stage to mature pollen, using cytochemical methods. To detect the distribution and dynamic changes of insoluble polysaccharides, lipid bodies, and proteins in the anthers through progressive(More)
In this study, ultrastructures of anther wall and sporogenous tissue of Leucojum aestivum were investigated during different developmental stages. Cytomictic channels were seen between pollen mother cells during prophase I. Polar distribution was described in the organelle content of pollen mother cells and microspores in early phases of microsporogenesis(More)
In this study, seed germination percentages, effects on phases of mitosis and α-amylase enzyme activity of lentil seeds treated with four different concentrations (0.25, 0.5, 1 and 1.5%) of Fusilade (Fluazifop-p-butyl) were determined. Median EC (effective concentration) values were calculated according to seed germination percentages after treatment for 72(More)
In this study, chromosome number and ploidy levels of Ipheion uniflorum cv. "Wisley Blue" (spring starflower) were determined. In meristematic root tip cells, chromosome number was found as 2n = 12 and 4n = 24. The ratios of diploid and tetraploid cells were found as 80.74% and 19.26%, respectively. In differentiated root tissues and mature leaf tissues(More)
In this study in vitro pollen germination test was performed on 7 different plant species in basic medium. These were; Malva sylvestris L. (Malvaceae), Ecballium elaterium (L.) A. Rich. (Cucurbitaceae), Lonicera fragrantissima Lindley (Caprifoliaceae), Cyclamen hederifolium Aiton (Primulaceae), Linaria vulgaris Miller (Scrophulariaceae), Antirrhinum majus(More)
In this study, morphological and anatomical features of Ornithogalum nutans and O. boucheanum, two relative and morphologically similar species growing in European Turkey, were investigated. These species showed some important anatomical differences with regard to leaf anatomy while they have identical features in stem. The stem anatomy of these two species(More)
In this study, gynoeceum, development of megasporangium, megasporogenesis, megagametogenesis and female gametophyte of Leucojum aestivum were examined cytologically and histologically. Ovules of L. aestivum are of anatropous, bitegmic and crassinucellate type. Inner integument forms the micropyle. Archesporial cell develops directly into a megasporocyte.(More)
In this study anther wall, meiosis, sporogenesis and the development of female gametophytes of Bellevalia edirnensis were examined cytologically and histologically. The young anther wall consists of an epidermis, a single layered fibrous endothecium, 1-2 middle layers which disappear early, and a single-layered tapetum. In the glandular tapetum; normal(More)
