摘要:
研究龙眼品种分类国内尚属空白。本文作者着重对福建三个龙眼主产区(泉州、莆田、福州)的10个主栽品种,探讨品种之间在形态结构上,具有共同遗传性状的稳定器官,作为龙眼品种类群分类模式的划分依据。并从酶学上加以印证。其目的在于为今后建立我国完整的龙眼品种分类。近期研究结果认为龙眼种子的种顶面观最为稳定且易于认别,可作为分类的第一级标准。同时,结合种子上胎座束突起,柱头开裂程度和叶形等,将福建主栽龙眼品种划分为三个品种群(红核仔、油潭本、福眼),六个类。并作出类群分类检索表。
Abstract:
An observation on ten typical longan varieties in three important lon-gan productive regions of Fujian Province (Fuzhou, Putian, Quanzhou) is reported. It attempted to find out the organs of steady inheritance in different varietal populations by means of examination of botanical characters. In order to establish a complete classification of longan varieties, and to be confirmed by enzymology, it will make a further study on the attribution of other longan varieties inside and outside Fujian Province.The results of recent research demonstrate that the shape of longan seed top is steadily inheritable and easy to recognize.So it can be regarded as a leading mark for classification. Based on this and also on the shape of placentations and the open size of stigma and the shape of leaves, Fujian longan varieties may be divided into three populations and six groups.1.Honghe Zhi population:Honghe Zhi group(including Honghe Zhi, Puminang, Jiaoyan ), Dongbi group (including Dongbi, Dapilong);2.Yu Tanben population:Yu Tanben group, Wunonglin group;3.Huyan population:Huyan group (including Huyan, Chike ), Sui-zhang group.The key to the variety populations of longan is listed.
