INVESTIGAION ON D ISTR IBUTION OFEUPHORBIA TIRUCALLIIN THE WORLD

绿玉树(Euphorbia tirucalliL.)原产非洲各国,在亚洲、欧洲、美洲和澳洲都有引种栽培。我国的部分地区也有绿玉树的引种栽培。绿玉树在我国香港的部分地区、台湾的澎湖列岛、海南西部和南部沿海引种以后已经逸为野生;西双版纳作为观赏树种有少量露地栽培;广州、昆明均在温室内栽培。调查结果表明绿玉树适应在干旱炎热地区生长。

Origin of Euphorbia tirucalli is Mrica. Introduced from Mfica as a garden plant, it is now planted in tropical areas and rainforests in Asia, Europe, America and Australia. It is introduced into some areas of China. Euphorbia tirucalli is distributed as wild plant in Hongkong, Taiwan and Hainan island, planted naturally as a garden plant in Xishuangbanna. It is planted as ornamental plant in greenhouse in Kunming, Yunnan Province and Guangzhou, Guangdong province. The results reveal that Euphorbia tirucalli is adaptable to a range of sites, including drought, tropical zones.
