摘要: 本文研究了糜子(Panicum miliacum L.)大孢子及雌配子体发育动态,主要结果为:雌蕊为2心皮合生,1室,内含1横生胚珠,双珠被,薄珠心.珠孔由内珠被形成,孢原细胞发生于珠心表皮下,直接起大孢子母细胞作用.大孢子母细胞经减数分裂形成线形排列的四分大孢子,珠孔端3个退化,合点端为功能大孢子.胚囊发育为蓼型,成熟胚囊由8核7细胞构成.受精前,反足细胞经分裂增至4~6个.

Abstract: A series of events during the development of the megaspore and the female gametophyte of Panicum miliaceum were studied by means of the regular histo-cytological and histochemical technique. The following is the main conclusions.The gynoecium is digynia, one locule, containing one hemianatropous ovule which is bitegminal and tenuinucellate. The micropyle is formed by the inner integument.The archesporical cell was hypodermal in origin and directly functioned as the megaspore mather cell. The meg...
