本文首次报道了苎麻属野生近缘种１５种７变种在种植条件下的主要特征特性和纤维细胞的形态结构。野生近缘种的出苗期与茎木质化程度有关，现蕾开花期一般在９月；种间农艺性状差异显著，野生近缘种明显劣于栽培种；野生近缘种抗寒能力较强，但大部分抗旱能力较弱；种间纤维细胞在外观形态上无明显差异，主要体现在单纤维细胞的长度、直径、壁厚、节间距离等解剖结构上。对野生近缘种在无融合生殖、品质改良、抗逆性及其开发利用潜力进行了评价和讨论，并提出了利用的途径与方法。关键词
This paper reports for the first time the main characteristics and morphological characteristics of 15 species and 7 varieties of wild relatives of ramie under planting conditions. The emergence of wild relatives was related to the degree of stem lignification, and the flowering and flowering buds were generally in September. There were significant differences in agronomic characters between the two species, and the wild relatives were obviously inferior to the cultivated ones. However, most of the drought-resistant abilities were weak. There was no significant difference in the morphology of interspecific fibroblasts, which mainly reflected in the anatomical structure of monofilament cells such as length, diameter, wall thickness and internode distance. The wild relatives in apomictic reproduction, quality improvement, resistance and potential of its development and utilization were evaluated and discussed, and put forward ways and means of use.
