“…Tapetal crystals similar to those in Dcenuuliuni also occur in some other legumes (Buss, 1969). Although quite conspicuous in polarized light, they are usually easily seen with ordinary brightfield optics as well (Fig.…”

“…ApPIWXIMATELY 70 publications mention some aspect of anther or pollen development in legumes (Davis, 1966;Buss, 1969). At the light microscope level Hindmarsh's (1964) study of Trifolium praiense is probably the most thorough.…”

“…During an investigation of tapetal characteristics of legumes (Buss, 1969), certain unusual features were noted in several species of Desmodium, particularly crystals restricted to tapetal cells. Further observations on anther development were made in D. glutinosum and D. illinoense.…”

Each of the four microsporangia has three or four wall layers, a uninucleate tapetum of various cell shapes with nuclei that remain in prophase, and 12‐24 pollen mother cells (PMCs). A sterile transverse septum sometimes bisects the microsporangium. PMCs secrete callose but not uniformly, and contact among them continues through meiosis. Simultaneous cytokinesis by furrowing isolates each microspore in callose, which later disperses. The separated microspores become vacuolate, undergo mitosis to become pollen, and later become filled with food reserves. Endothecial wall thickening and tapetal dissolution occur after pollen engorgement. Calcium oxalate crystals form in tapetal cells during the sporogenous stage, reach maximum size during early meiosis, and remain prominent until tapetal dissolution.

“…Tapetal classification based on nuclear number (Cooper, 1933) has merit in taxonomy. In Rosaceae, the tapetum is either constantly uninucleate or else binucleate to multinucleate (Buss, 1971). In C. tanacetifolia, at sporogenous tissue stage, a tapetal cell has usually single nucleus with a single nucleolus.…”

In this study, the development of male reproductive organ was analysed in Crataegus tanacetifolia (Lam.) Pers., endemic to Turkey. Androecium is composed of 20 stamens which are attached at the base of the filaments. The anther wall formation follows the dicotyledonous type. The undifferentiated anther is ovoid-shaped, and the differentiation starts with the appearance of archesporial cells. Mature anthers are dorsifix and tetrasporangiate. The anther wall is composed of an epidermis, endothecium, two or three rows of middle layers and secretory tapetum. Endothecial cells show fibrous thickening. Tapetum is characterized by enlarged secretory types with binucleate cells, which presented an intense reaction with regard to proteins, insoluble polysaccharides and lipids. Features of chromatin condensation and nucleus disorders identified with the application of DAPI (4Â´,6-diaminido-2-phenylindole) point out programmed cell death. Epidermal and endothecial layers remain intact until anther dehiscence; however, middle layer and tapetum disappear during development. At the end of regular meiotic division, tetrahedral microspore tetrads are formed. Pollen grains are tricolparatae, tectate and sphaeroidea. Exine is made up of lipoidal substances and proteins, but the intine includes insoluble polysaccharides. Further, cytoplasm of pollen grains are rich in proteins, lipids and insoluble polysaccharides.
