Résumé

Microsporogenesis and development of the male gametophyte of Allium senescens L. were studied by use of paraffin sections. The anther was found to be four-sporangia. Its wall includes four layers: epidermis, endothecium, middle layer, and secretory tapetum. Cytokinesis during meiosis of microspore mother cells (MMCs) is successive. Most mature pollen grains are two-celled, a few are three-celled. In addition, anomalies were observed during meiosis of MMC and in uninucleate microspores, including laggard chromosomes, lagging chromosomes, anaphase bridges, and micronucleus. These anomalies are possible reasons for abortive pollen.
