采用石蜡切片法对粗柄独尾草大、小孢子发生及雌、雄配子体发育过程进行研究,结果表明:粗柄独尾草花有6枚 雄蕊,每枚花药具4个花粉囊,花药壁由外向内分为表皮、药室内壁、中层和绒毡层,绒毡层为腺质型.小孢子母细胞减数分裂后胞质分裂为同时型,四分体呈四面体型,成熟的花粉粒为2细胞型.粗柄独尾草为单子房,3室,每室4枚胚珠,胚珠横生,胚囊发育为贝母型.
The microsporogenesis,megasporogenesis and development of female and male gametophytes of Eremurus inderiensis were studied by paraffin-embedded sectioning technique.The results showed that there were six stamens,anthers with four locules.The anther wall grows into epidermis,endothecium,middle lamella and tapetum which was corresponds to glandular type from out side to inside.The meiosis of microspore mother cell belongs to simultaneous type and resulted in tetrahedral tetrad,the mature pollen grain was of the 2-celled.Eremurus inderiensis had single ovary with three rooms and each room had 4 hemitropous ovules,the development of embryo sac was fritillaria type.
