英文摘要	通过扫描电镜和常规石蜡切片技术,观察了柏科4个属(Fokienia、Cupressus、Chamaeyparis 和Juniperus)植物雌球果中胚珠的发育及苞片的结构变化.在所有研究的种类中,可育苞片腋部最先观察到的结构是一扁平的突起,并在其上分化出发育为胚珠的胚珠原基.在雌球果的发育过程中,未观察到独立的珠鳞发育.不同的种中,胚珠怕数量和发育顺序有所不同,但苞片的发育是相似的.传粉前,苞片的结构与叶相似.传粉后,由于剧烈的居间维管束发育.我们还对柏科植物雌球果的形态学特性及其可能的演化趋势进行了讨论.; The ontogeny and vascular systems of female cones of the Fokienia, Cupressus, Chamaecyparis and Juniperus were investigated in detail using scanning electron microscopy (SEM) and conventional light microscopy. In the species examined, in the axils of the bracts, the first recognizable structure was a broad meristematic swelling, from which ovules developed. No ovuliferous scales developed during the ontogeny of the female cones. The number of ovules and ovule developing sequence displayed considerable variation in different species. However, development of the bracts was similar in all of the investigated species. Following pollination, the foliage-like bracts became peltate bract scales due to intercalary expansion, and global cones formed. In addition, the vascular system in the bract scales became intricate, and inverted vascular bundles emerged in the adaxial of the mature bracts. Based on these observations, a morphological interpretation and possible evolutionary trend of the Cupressaceae female reproductive structures was discussed.; 中国科学院知识创新工程项目; 国家自然科学基金; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000224034800010&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 1; 9; 1075-1082; 46
