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, 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, 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 anther ontogeny of Campsis radicans (L.) Seem. was investigated by transmission electron microscopy and light microscopy with special reference to the development of the anther wall. The anther wall formation follows the dicotyledonous type. The differentiation in anther starts with the appearance of archesporial cells which undergo periclinal(More)
Calcium oxalate crystals, which are found in many organs of plants, have different morphological forms: as druses, prism, styloids, raphides and crystal sand. In this study, the distribution, type and specific location of calcium oxalate crystals in the leaves and stems of the eight species of poisonous plants and one species of nonpoisonous plant were(More)
