From 1995 to 1998 and in 18.8~34.2°N,101~121°E, namely in the Changjiang valley and southern 14 Provinces (cities) or autonomous regions, 220 wild germplasm resources of nettle family, had been collected, among which are 130 ramie accessions belonging to 20 species and 6 varieties. A china wild ramie germplasm nursery also has been established for preserving 77 wild ramie germplasm accessions of 8 species and 4 varieties, and 34 wild germplasm accession of other 9 genera of nettle family. According to their morphological characters, the ramie germplasm are classed as axillary-bulb Boehmeria, Boehmeria group, ordinally-leaved Boehmeria and largely-leaved Boehmeria. With its distribution related to the elevation, wild ramie population can be divided, in the light of its ecological adaptation characteristics, into four ecological groups as follows: hygrophyte, medium-wet type, semi-humid type and xerophtic type. In order to conserve the wild ramie germplasm resource, which live in different regions with different climate and ecological conditions and so, has the relatively low survival rate when preserved in other regions, it is necessary to create favourable condition of water, air, light and temperature for its growth through the year.

1995~1998年,从φN(18.8°~34.2°)、λE(101°~121°)之间,在我国长江流域及以南14个省(市)、自治区、34个县(市)搜集到荨麻科野生资源222份,其中苎麻属130份,分属20个种6个变种。建立了中国野生苎麻种质资源圃,保存野生苎麻种质8个种4个变种共77份材料和荨麻科其它9个属野生资源34份材料。根据形态特征,将已搜集到的苎麻野生资源划分为腋球苎麻组、苎麻组、序叶苎麻组、大叶苎麻组四个组。野生苎麻的种群分布与海拔高度有关,按其生态适应性特点分为湿生性种、湿中性种、半阴湿性种和旱性种四大生态类型。来自于不同地域、不同气候和生态环境的野生苎麻,易地保存成活率偏低,建圃保存时要从水、气、光、温等多方面创造有利条件,满足其终年生育需要。

Through the method of CTAB,Total DNA of wild Ramie was extracted.According to the character of wild Ramie that it contains lots of secondary metabolites such as alkaloid and phenli, high molecular mass DNA can be obtained by adding certain concentration of PVP,Mercapto Ethanol into extraction buffer. The results of the experiment show its purity can satisfy the demand of molecular genetic experiment.

用CTAB法提取野生苎麻总DNA ,结合野生苎麻中酚类、黄酮类等次生代谢物质多的特点 ,加入一定浓度的PVP、β—巯基乙醇 ,可以获得高分子量DNA ,经实验鉴定 ,其纯度符合分子遗传实验要求。

The nursery of wild ramie germplasm which were collected from the Yangtze valley and 14 southern provinces or autonomous regions was set up.With con- trolled growing environment,the characteristics,stress resistance,apomixes of the wild germplasm in Boehmeria were observed and studied.Further utilization was discussed.

把从我国长江流域及以南14个省(市、自治区)搜集到的苎麻属野生种进行建圃保存,通过对其生长环境条件的控制,观察和研究野生种的植物学特征、主要经济性状、抗逆性、无融合生殖特性等,并对其有效利用进行了进一步的探索。
