Embryological characters of Arundinaria simonii f. heterophylla were reported in this article. The anthers were tetrasporangiate in which the cytokinesis of microsporocyte in meiosis was successive type and the produced microspore tetrads were bilaterally symmetrical. The cells of tapetum layer with dense cytoplasm were secretory type, and they began to degenerate during meiosis division. The mature pollen was trinucleate. The single ovule with parietal placenta was anatropous, double integument and tenuinucellatae. The development of the embryo sac was polygonum type. Generally the florets close to the base of spikelets bloomed earlier than others, and development of both stamens and pistils within a spikelet was synchronized.
以淡竹(Phyllostachys glauca Mc Clure)为研究材料,对花期物候、花序形态结构等进行研究。结果显示:淡竹为续次发生花序,盛花期为4月30日至6月5日,开花时顶部花先开,内、外稃不张开,果实为颖果;淡竹花序由小穗组成,每一小穗仅含1朵小花;小花具内、外稃各1枚,浆片3枚,雄蕊3枚,雌蕊1枚,柱头为长花柱型。雌雄同熟。
