入侵植物五爪金龙研究和利用进展

五爪金龙是以一种优良的立体园林植物引入我国,后逸为野生,成为我国南方地区恶性入侵杂草之一,对我国华南地区的自然和人工生态系统造成严重破坏。本文主要综述了五爪金龙的生活史、危害与防治,以及与本地物种化学关系的研究和利用价值进展。值得一提的是,研究表明五爪金龙能够合成大量的次生物质,这些物质不仅对五爪金龙成功入侵有关,也有很多应用价值。开发和利用五爪金龙的次生物质可使其＂变害为宝＂,将是今后五爪金龙研究的一个重要内容.。

Advances in Researches and Usages of an Invasive Plant Ipomoea Cairica

Ipomoea cairica had been introduced into China as a garden plant about one hundred years ago,however,it bacame an invasive weed in southern China soon.I.cairica damaged to natural and managed ecosystem seriously in south China and other south-east Asia countries.We summarized researches about I.cairica life cycle,harm and treated,chemical relationship with native species,and values of utility.Many reports demonstrated that I.cairica could synthetise a lot of secondary metabolites,that involve not only in its successful invasion,but also in its application.So,it could be valuble that to discover how to make I.cairica from an unfavourable into favourable in future.
