Observation on Morphology and Histological Characteristics of Flower Organs of Spathiphyllum
Abstract：Spathiphyllum is a perennial herb of Araceae, which is native to Central and South America and Southeast Asia and is one of the most popular indoor foliage plants in Europe. Spathiphyllum has a unique flamingo, highly ornamental value. But at present, there are few reports on the research of the flowering characteristics and inflorescence structure of Spathiphyllum at home and abroad. In this study, four potted cultivars of Spathiphyllum varieties were used to study the flower bud differentiation process, floral inflorescence traits and flower structure. The differentiation of flower buds was pided into six periods: the differentiation period, the bract stage primordium differentiation stage, the inflorescence primordium differentiation stage, the inflorescence primordium enlargement stage, the differentiation stage of the flower primordium and the differentiation stage of the flowers. The structure of Spathiphyllum is bisexual flower, which is composed of perianth segments, stamens, pistil and ovary. It can be pided into four types according to the number of perianth segments, namely, four perianth, five perianth, six perianth and eight perianth type.

白鹤芋花器官形态及组织学特征观察
引言白鹤芋( Spathiphyllum kochii Engl. & K.Krause)，又称白掌、和平芋、苞叶芋，为天南星科、苞叶芋属多年生草本植物，原产中南美洲和东南亚[1]。白鹤芋的原产地是哥伦比亚，生长于热带雨林中，因其具有观赏性极强的佛焰花序，以及独特的叶形，兼具观花观叶的特性。白鹤芋不仅生长旺盛，耐阴，还具有过滤有毒气体的作用，深受人们的青睐，因此常用于室内美化装饰，成为欧洲最受欢迎的室内观赏植物之一。20世纪80年代开始大量作为商品性观赏植物引人中国, 近年来，随着我国人民生活水平的提高，白鹤芋一直供不应求[2]，成为了中国观叶植物产业发展的先锋和重要观叶植物[3]。
