development of floral organs-
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
對數珠珊瑚的花器官發生和子房的發育過程進行了觀察.結果表明: ( 1 )數珠珊瑚花被呈2 / 5螺旋狀發生,遠軸側的1枚先發生,其次為近軸側的1枚發生,最後側方的2枚花被幾乎同時發生,第3枚花被在靠近第1枚的位置發生,第2枚和第3枚之間有1個空隙; ( 2 ) 4枚雄蕊是同時發生的; ( 3 )心皮發生於分生組織的遠軸側,心皮原基形成后,向上向軸生長,在子房成熟前在近軸側非正中位形成1個孔,該孔為心皮最終愈合前的殘跡,到子房成熟時,因子房的生長孔被擠壓縮小,在進一步的生長過程中愈合.子房由1枚心皮構成; ( 4 )從子房發育過程的切片看,該植物的胚珠是在子房發生后不久發生的,子房上的圓孔形成時,從近軸側的分生組織發生胚珠原基,由胚珠原基分化出珠被與珠心This article reviews the recent research advances of floral formation ( including floral induction, identification of inflorescence, floral evocation and floral morphogenesis ) in plants ( taking example by arabidopsis and antirrhinum )
摘要以擬南芥、金魚草為例,介紹了近幾年植物成花(包括成花誘導、花序分生組織的組成、花發端、花器官發生及發育)研究的一些進展。The results were as follow : in the process of its male organ development, these are many abnormalities, such as : premature tapetal degradation, giant tapetal cells, the great vocalization of the tapetal cells and inadaptable function of callose enzyme, which lead abnormal and premature degradation microspores and male gametophytes
實驗結果表明: 1蝟實的雄性生殖器官在發育過程中,出現絨氈層細胞的液泡化、肥大、提前降解及不適時釋放胼胝質酶等異常現象,造成蝟實花粉發育過程中出現畸形、解體。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
其上方花轉化初期的花萼片、花瓣和雄蕊中總表現有心皮的標記性性狀? ?被毛、帶有心皮的形態和解剖結構痕跡,上方花花萼片的解剖結構中存在有類子房結構,花萼片、花瓣和雄蕊與心皮形成復合結構等,提出其上方花的各類器官都是由心皮原基異形化轉化發育而形成的觀點。All above indicates that short daylength promoted flowering in salicornia bigelovii torr. on the contrary, long daylength inhibited both its floral induction and development of post - flowering

葡萄主梢和副梢花器官與種子發育的研究Four species of ceratiodes were studied about organic morphology and embryonal development and biological characteristics. the results were showed as follows : c. arborescens and c. ewersmanniana were more dominant than c. latens and c. lanata in spire and vegetative period. in flowering phase of male flower, c. arborescens and c. latens arrive the maximum peak of flowering during 8 : 00 - 11 : 00. c. lanata arrive the maximum peak of flowering during 11 : 00 - 1 : 00, but in flowering phase of female flower, three species arrive the maximum peak of flowering in 14 : 00 ; temperature of female flower was righter than one of male flower
本文對駝絨藜屬4種植物進行了器官形態學及解剖學、胚胎發育及生物學特性的研究,結果表明: 4種材料幼苗期和營養生長期的生長狀況均是華北駝絨藜、心葉駝絨藜比駝絨藜、北美駝絨藜占優勢;開花規律,華北駝絨藜和駝絨藜雄花均在8 : 00 - 10 : 00達開放高峰,北美駝絨藜在11 : 00 - 1 : 00達開放高峰,而三者雌花均在14 : 00左右達開放高峰。Meanwhile, morphological characteristics of d. glomerata have significant relationships : those with upright and constrictive inflorescences have longer and narrower leaves, stronger stems, longer flag leaves, well - developed stamens and stronger seed reproductive capacity, whereas those with pendulous inflorescence have the opposite characteristics
