carpellary primordia
Examples
- In this paper the floral ontogeny and the ovary development of rivina humilis l . were observed . the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals . the abaxial one initiated first , then the adaxial one , finally the lateral two initiated nearly simultaneously . the third one initiated on the position near the first tepal , and there is a gap between itself and the second tepal . ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time . ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed , therefore an elliptic orifice was formed at the adaxial position of ovary , which was the remainder of the mouth of ovary before the ovary was fused completely . with the ovary maturing , the orifice was narrowed because of the ovary growth , at last fused completely . the gynoecium is composed of a single carpel . ( 4 ) in the series developmental sections of ovary , the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed
对数珠珊瑚的花器官发生和子房的发育过程进行了观察.结果表明: ( 1 )数珠珊瑚花被呈2 / 5螺旋状发生,远轴侧的1枚先发生,其次为近轴侧的1枚发生,最后侧方的2枚花被几乎同时发生,第3枚花被在靠近第1枚的位置发生,第2枚和第3枚之间有1个空隙; ( 2 ) 4枚雄蕊是同时发生的; ( 3 )心皮发生于分生组织的远轴侧,心皮原基形成后,向上向轴生长,在子房成熟前在近轴侧非正中位形成1个孔,该孔为心皮最终愈合前的残迹,到子房成熟时,因子房的生长孔被挤压缩小,在进一步的生长过程中愈合.子房由1枚心皮构成; ( 4 )从子房发育过程的切片看,该植物的胚珠是在子房发生后不久发生的,子房上的圆孔形成时,从近轴侧的分生组织发生胚珠原基,由胚珠原基分化出珠被与珠心 - On basis of the fact that some organs in the highflower usually appear pappus - a carpellary marked trait , or carpellary morphological trace or anatomical character in the process of transforming development , deem that the highflower origins from the heteromorphic development of carpellary primordium . furthermore , the course and mode of heteromorphic development of different organs in the highflower have been described , and according to the organ composition in highflower , the prolification flower is divided into green prolification , colorful prolification , golden prolification and three - strata prolification
其上方花转化初期的花萼片、花瓣和雄蕊中总表现有心皮的标记性性状? ?被毛、带有心皮的形态和解剖结构痕迹，上方花花萼片的解剖结构中存在有类子房结构，花萼片、花瓣和雄蕊与心皮形成复合结构等，提出其上方花的各类器官都是由心皮原基异形化转化发育而形成的观点。
