摘要: 对葡萄心皮融合过程以及雌蕊各部分形成进行了详细观察。在早期发育阶段心皮是分离的,随着发育心皮原基出现并不断分裂增长,基部对应两侧初生分生组织向中心靠拢,靠拢的心皮初生分生组织以远轴背腹面表皮细胞相互连合,进而细胞再分化变为薄壁细胞,心皮原基以折叠方式进行融合,融合细胞向上生长分化花柱和柱头,向下则构成子房组织,将子房隔成2室。3心室子房的形成可能有两种方式,即生殖后融合与特殊区域生殖后融合 、

Abstract: The detailed ontogeny of postgenital fusion within the gycoecuim systematically investigated with light microscopy in ‘Kyoho’ grapevine.The result shows that the two carpels are free at the early stage of floral ontogeny.During normal floral development the two carpels primordial initiated.The separate carpels primordial lateral growth continuously upward with opposing distal tips of the two carpels primary meristem approached
to each other.The adaxial surfaces of two carpels primordial contacted at upon ovary regions,and the epiderm al cells in the contact zone rapid redifferentiation into parenchymatous cells.As a consequence of this epidermal cells redifferentiation the carpel become fused by the infolding,and this region then proceeds to develop into the style,the stigma,and the distal region of the ovaries.After the completely fusion carpel of ovary formed two locules separated by a septum.Ferthermore,this paper indicated that the ontogeny of three carpels of ovary with two patterns in grapevine.
