纹瓣悬铃花的生物学特性与生态适应性研究

以纹瓣悬玲花（Abution striatum Dickson）为材料，通过调查与栽培试验，研究其生物学特性与生态适应性，探讨园林应用的可能性。结果表明：纹瓣悬铃花花期特长、花形奇特、花色艳丽，具有优良的植物学性状和景观效果；在有效防治病虫害的前提下，无性繁殖成活率高；成年植株未见明显的病虫危害，但夏季扦插及幼龄期需防治白绢病；采用摩擦接种南瓜花叶病毒有感染现象；纹瓣悬铃花喜温暖、湿润和阳光充足的气候环境，适宜肥沃、疏松、排水良好的微酸至微碱性土壤环境；冬季-3.5 ℃极端低温环境下可越冬；园林应用中需采取相应的技术措施。

Study on the Biological Characteristic and Ecological Adaptability of Abution striatum Dickson

Using Abution striatum Dickson as material,the biological characteristic and ecological adaptability were studied by inquirying and planting experiments in order to probe into the possibility in gardens application.The results indicated that Abution striatum Dickson had a long-term florescence,the flower shape was peculiar and flower colour was flamboyant.So the plant took on eximious botany character and landscape effect.The survival percentage of vegetative propagation was higher as long as the plant diseases and insect pests were prevented and cured effectively.The grown trees did not be infected obviously with plant diseases and insect pests,but Corticium rolfsii Curzi was prevented necessarily during the courses of cuttage in summer and young tree could be infected with Squash mosaic disease virus by rubbing inoculability.Abution striatum Dickson was fond of the warm and moist and sunny climate,the fertile and loose and draining and from sourish to alkali soil.It could live through the winter under the extreme low temperature-3.5 ℃.Therefore,the corresponding techniques should be adopted while being applied in gardens.
