单词	sporogenesis
释义	sporogenesis /ˌspɒrə(ʊ)ˈdʒɛnɪsɪs / /ˌspɔːrə(ʊ)ˈdʒɛnɪsɪs/ noun [mass noun] chiefly Botany The process of spore formation.Male sporogenesis begins with the division of a diploid sporophytic cell that gives rise to the tapetal initial and the sporogenous cell.... This strongly suggests that the dyads corresponded to the final stage of sporogenesis and therefore that they occurred from a meiosis II-like division, rather than from a disrupted meiosis I. In the final stages of sporogenesis, a dense perine is deposited on the spore surface.
