| 摘 要： | 本文描述扫描电镜和实体解剖镜下观察到的花生(Arachis hypogaea L.)花芽分化过程。包括在幼胚发育中第一个花序原基分化、播种后子叶出土前第一个花芽原基分化、幼苗生长过程中花器分化和生长形态。辨明了花序苞片与混合芽芽鳞的区别以及花生花序的确切类型;证实通常称为萼管的管状物由花萼、花瓣和花丝等部分参与组成,并认为这一管状物应称为花管较确切。

| Abstract: | Process of peanut inflorence primordium development has been observed with scannidg microscopy and plastic thin section microscopy. It includes that an observation cf the first inflorencence primordium development during embryo formation, the first flower primordium differentiation during seed germination, and the morphogenesis of every component of a flower while young seedling grews up. A few discoveries have been obtained, i. e., inflorencence bract and shoot scale having different morphogenesis origination should not be obscured, the inflorencence type of peanut belongs to spike inflorencence not racemose, and the socalled calyx tube is made up of calyces, petals and filoments but not modified calyx. Therefor the tube-like thing should be named flower tube in lien of calyxtube. |
