An investigation of wheat germplasm was conducted at Chayu County, Xizang(Tibet) Autonomous Region in 1982. Three aspects; including (1) the local ecological environment factors, (2) wheat species group and varietal population, and (3) ecological distribution of wheat are discussed in this paper. Two varieties have not been discovered in China.

本文系根据在西藏察隅县的考察,从察隅县的小麦生态环境,察隅县的小麦种群和变种群体及它们的生态分布三个方面,对小麦的生态特性与生态环境的关系进行探讨。有两个变种是国内未曾报道的。

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.

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。

The ecological structure of nine stands in Xiao Long Mountains and Qi Lian Mountains were investigated to determine the species diversity and the dissimilarity value.The differences between the two vegetation types as well as the varietal populations of each type were expressed using ordination method.The purpose of this study was to supply some theoretical basis for drawing up the forest management measure.
