野生玫瑰种质资源分布现状及预测

Distribution Status and Its Prediction of Rosa rugosa Germplasm Resources

野生玫瑰是珍稀濒危植物,被列入我国二级保护植物目录。目前,大量研究针对野生玫瑰种质资源保育展开,但较少对其种质资源分布现状及预测进行总结性报道。本研究通过文献查阅、资料收集等对野生玫瑰种质资源分布现状及特征进行分析,并在已有研究基础上对野生玫瑰自然条件下的潜在分布区进行预测。结果表明野生玫瑰主要分布于滨海地区,在东亚地区为原生植物,在欧美大陆则逃逸成为入侵植物。预测模型显示东亚地区滨海区域仍为野生玫瑰主要潜在分布区,并且有向内陆地区扩散的趋势。本研究通过种质资源调查分析并通过模型预测对野生玫瑰分布状况进行初步总结,将对野生玫瑰引种栽培、未来分布区域预测等起到一定的支撑作用。

Rosa rugosa,a rare and endangered plant species,is taken as a plant of the second-class protection in China.At present,a great deal of studies have focused on the conservation of R.rugosa germplasm resources,while distribution status and prediction of its germplasm resources are rarely summarized and reported.Herein,we analyzed the distribution status and characteristics of R.rugosa germplasm resources by the way of literature review and data collection,and predicted the potential distribution area under the natural conditions of R.rugosa based on the existing researches.The results showed that R.rugosa mainly distributed in coastal areas.It was native plant species in East Asia and was regarded as invasive plants via escaping into Europe and America.Predictive models demonstrated that the coastal area in East Asia is still the main potential distribution area of R.rugosa,and it tended to spread into inland.Overall,our study preliminarily summarized the distribution of R.rugosa through analyzing the germplasm resources investigation and model predictions,and would play a certain scientific supporting role in the introduction and cultivation of R.rugosa as well as its future distribution prediction.
