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。 This article describes the flower bud differentiation process of peanut (Arachis hypogaea L.) observed under SEM and SPM. Including the first inflorescence primordial differentiation in immature embryo development, the first flower primordia differentiation before cotyledon unearthed after sowing, the differentiation and growth pattern of flower organs in seedling growth. The distinction between inflorescence bracts and mixed bud scales and the exact type of peanut inflorescence were identified; it was confirmed that the tube, commonly known as calyx tube, was composed of calyx, petals, and filigree and was believed to be called a flower tube More exact.
