中国苎麻属野生种资源的特性及利用

:在人工圃中对采自国内 1 4个省份的苎麻属野生种的生育特性、生物学特性、经济性状及抗性进行了观察 ,结果表明 :大多数野生种的出苗期在 3月份 ,现蕾期在 8～ 9月份 ;丛生类野生种的茎直立 ,分株力中等 ,散生类野生种的茎半直立 ,分株力强 ;平均株高、茎粗、皮厚分别为 1 3 7.8cm、0 .63cm和 0 .5 3mm ,经济性状好的野生种抗性强。讨论了中国苎麻属野生种资源的利用与保存

Characteristics and Utilization of Wild Germplasm Resources in Boehmeria in China

The growth and developmental characters, biological characteristics, economic characters and resistance of wild species in Boehmeria collected from 14 provinces in China were observed in artificial nursery, the results indicated that: for most wild species, the seedlings emerged in March, the flower buds appeared from August to September; the wild species growing in clumps had erect stem and middle ability of plant division, those growing loosely had semi-erect stem and strong ability of plant division; the average plant height, stem width and bark thickness were 137.8cm, 0.63cm and 0.53mm respectively, the wild species with good economic characters had strong resistance. The paper also discussed the utilization and conservation of wild germplasm resources in Boehmeria in China.
