• In paeonia were studied systematically about the formation of prolification flower , the diversity of carpellary disc and the relationship between it and carpel , the carpellary morphology and anatomy , petaline types and origination , etc .
• After comparatively researching the morphology , anatomy and development process between carpel and leaf , we put forward a viewpoint that the carpellary disc of paeonia is not from the receptacular projection , but is a appendant organ of carpel . they come from leaf blade and leaf sheath separately . ( 3 ) after researching carpellary morphology and anatomy of nine groups of sect
• On basis of the facts that all tubiform petal only occurs in the highflower of prolification flower ; and except the tubiform petal , the rest of the highflower petals always have the transforming development carpellary disc in the dorsal base ; as well as there are distinctive shape and anatomy structure , a viewpoint that the tubiform petal corns from the together petaloid developing of carpel and carpellary disc has been put forward . furthermore , the jointly petaloid development process and feature of the tub
• ( 2 ) there are some difference between the carpellary disc in the prolification flower and the carpellary disc in non - prolification flower . the carpellary disc of lowflower in prolification flower is similar to the carpellary disc in non - prolification flower , jointing into cup - shaped or dish - shaped each other surrounding carpel , or sometimes splitting from each other . but the carpel in highflower has itself carpellary disc that develops into various structure following with carpellary heteromorphic development
• 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
• 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
