扁叶刺芹引种表现和适应性研究

Introduction Performance and Adaptation Studies of Erygium planum L

为明确自然分布在新疆阿勒泰地区的野生扁叶刺芹(Erygium planum L.)在乌鲁木齐的引种表现和适应性,对其物候期、生长发育状况及对高低温的适应性等特征进行了观察。在引种地能够自然开花及结实,最佳观赏期为6—7月;在迁地条件下,植株的株高、茎粗、侧枝数、花序分级数、花序大小等指标均大于原生境中的个体;扁叶刺芹不仅对低温适应性强,对高温适应性也较强;蚜虫是引种地主要的虫害,没有明显病害,是一种用于引种地园林绿化的本土野生观赏植物资源。

The aim was to clarify the introduction and adaptability of Erygium planum L.naturally distributed in Altai,Xinjiang.The phenological period,growth and development status and adaptability to high and low temperature were observed.The results showed that the E.planum was able to flower and bear fruit naturally in the introduced site,best ornamental period to blossom was June to July.Under the ex-site conditions,the plant height,stem size,side branches,inflorescence sequence and inflorescence size were larger than the unit in the original habitat;the E.planum was not only adaptable to low temperature,but also to high temperature;aphid was the main pest in the introduced site,and it had no obvious disease.The E.planum was a kind of native wild ornamental plant resources suitable for the landscape greening of the introduced site.
