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
On the whole, the tr and gs of leaf of anthurium andraeanum lind decreased under elevated [ co2 ] and wue increased, these might be beneficial for the increase of pn and chlorophyll as well as accumulation of organic compounds which promoted plant growth and florescence and flower leaf area, furthermore, the improvement of quality
總之, co :加富條件下紅掌葉片的氣
孔導度與蒸騰速率降低,水分利用效率增加,凈光合速率提高,有利於碳水化合物的積累,促使紅掌的各項生長指標(株高、葉面積、生物量)提高,開

花期,提高了紅掌的觀賞品質。
And then, metal structure with aspect ratio 30 was obtained in our laboratory. eventually, a few micro parts with high aspect ratio were fabricated by liga process under the optimum condition. there were key parts of micro thruster, netlike nickel antielectron modulator, micro copper radiator, stainless steel micro components and many filter mediums with different shapes and dimensions
