| 摘 要： | 用常规石蜡制片法研究了川白芷大、小孢子发生及雌、雄配子体的发育过程.结果表明:川白芷的子房为2室,每室1倒生型胚珠,单珠被,薄珠心;大孢子发生过程中,具有多个孢原细胞的现象,但通常只有1个大孢子母细胞能继续发育;大孢子母细胞经减数分裂形成线形排列的4个大孢子,合点端大孢子具功能;胚囊发育属于蓼型.小孢子母细胞减数分裂过程中的胞质分裂为同时型,小孢子4分体为四面体形;成熟的花粉粒为3细胞型;花药壁发育为双子叶型,绒毡层为腺质绒毡层.

| Abstract: | The megasporogenesis and microsporogenesis as well as the development of male and female gametophytes of Angelica dahurica were investigated by using the conventional method of paraffin section.The results show that in the ovary of A.dahurica,there are two chambers with one unitegmic,tenuinucellate and anatropous ovule.During the megasporogenesis,only one megasopore can continue to grow and develop,though several sporogoniums and megaspores might appear.After the meiosis process,the megaspore mother cell is... |
