在冈山县鸟取大学平森森林中，研究了A. turbinata花蕾的形成和发育。生长点被多毛鳞片包围，生长浓密，分化为花芽原基。它生长迅速，花原基在花轴周围形成。7月底开始花药和子房分化，8月中下旬形成孢子细胞和幼胚珠。9月中旬观察到花粉母细胞和卵状胚珠。次年5月初花粉粒形成。花柱和花丝在5月中旬伸长，形成雌雄同体花。在胚珠退化的未成熟花中，只有花丝伸长并发育成雄花。根据9月中旬冬芽的形态，可以将花芽与营养芽区分开来。
The initiation and development of flower buds in A. turbinata were investigated in the Hiruzen forest of Tottori University, in Okayama Prefecture. The growing point surrounded with hairy scales grew thickly and differentiated to a flower bud primordium. It grew rapidly and flower primordia were formed around the floral axis. The differentiation of anthers and ovaries started at the end of July and sporogenous cells and young ovules were formed from mid to late August. Pollen mother cells and egg-shaped ovules were observed in mid September. Pollen grains were formed in early May of the next year. The style and filament elongated in mid-May and hermaphrodite flowers were completed. In immature flowers whose ovules were degraded, only filaments elongated and developed to male flowers. Flower buds were distinguishable from vegetative buds by the form of winter buds in mid-September.
