摘要 本文以锦橙为材料观察了汁囊的起源和整个发育过程.结果表明锦橙的汁囊起源于心皮内表皮的单个细胞.汁囊的原始细胞经过数次垂周和平周分裂形成由多细胞构成的球状体;球状体逐渐发育为伸长的柱状结构。在柱状结构的顶端中轴部分分化出一团分生组织细胞.这群分生细胞活跃地分裂和生长,使柱状结构上端膨大、加粗,最后发育成一个带有一条细长柄的囊状结构即汁囊. The origin and the whole development stage of the juice sac of Citrus sinensis (L.) Obs. 'Jincheng' were investigated. Results indicated that the juice sac originates from a single cell of the carpellary endoepiderdris. After the anticlinal and periclinal divisions of the initial cell, a multicellular globular-structure is produced. The globular-structure developes into a column6tructure with the differentiation of a cluster of meristem cells at its apex. As result of the active divisions and growth of the meristem cells, the column-structure expands and widens. At last the column-struCture developes into an expanding sac with a slender stalk that is the juice sac.
