| 摘 要： | 以山东境内发现的8株叶籽银杏正常种实和叶生种实为试材,对其种实形态多样性进行比较研究.结果表明:1)成熟的叶生种实具有明显的外种皮、中种皮、内种皮、胚乳、珠领.叶生种实形态上具有多样性,在叶顶端或边缘着生1～2(15)个大小不等的胚珠,珠领不连续.核体顶端锐尖,或直立,或为喙状,内种皮中缢线明显移向珠孔端、上端赤褐色的内种皮缺如或萎缩.种仁仅有胚乳、无胚.2)叶生种实质量和种核质量约为正常种实质量和种核质量的1/3,叶生种仁质量约为正常种仁质量的1/4.正常种实和叶生种实出核率分别为25.23%和20.16%,出仁率分别为74.26%,48.91%.对银杏的胚珠及种实的植物学和栽培学术语进行了说明.

| Abstract: | The morphological diversity of normal seeds and epiphyllous seeds of 8 Ginkgo biloba var.epiphylla trees discovered in Shandong Province was comparatively investigated.The results showed that: 1) the mature epiphyllous seed had significant sarcotesta,mesdotesta,endotesta,endosperm and collar.The epiphyllous seeds had morphological diversity,and 1 - 2 (15) ovules in various size bore on the leaf apex or margin and the collar was discontinuous.The end of mesdotesta was sharp,erect,or beak-like;the middle line... |
