Characteristics of the spore walls developing during the tetrad period have been studied in Lilium longiflorum using cytochemical methods and scanning electron microscopy. Following upon meiosis II, each spore forms a separate wall, the primexine. The primexine consists of a tenuous matrix component identified tentatively as cellulose, traversed by radially directed rods, the probacula. Initially these possess a lamellated or granular appearance, and are not resistant to acetolysis; their… CONTINUE READING
