铁线莲属植物的引种栽培研究初报

对部分铁线莲属（Clematis L.)植物进行了引种和栽培，根据花枝的着生情况把铁线莲分为3组。通过对野生种Cl.ranunculoides去年采收的种子进行有性繁殖，结果表明进行春化处理后播种的种子萌发率最高，达71％。对最适合在昆明生长的野生种Cl.ranunculoides和栽培品种Cl.montana‘Vera’进行扦插试验。结果表明Cl.montann ‘Vera’的生根率较高；扦插基质山沙优于珍珠岩；经NAA或IBA处理过的插条一根数多于对照。对栽培土壤进行了分析，结果表明大部分铁线莲也可在偏酸性土壤中生长。

A Preliminary Study on the Introduction and Cultivation of Clematis

Some species and cultivars of Clematis L. were introduced and cultivated.They were divided into three groups according to the different flower branch growth position. Seed propagation on Cl ranunculoides showed the vernalized seeds sowed in soil had the best germination rate up to 71 percent. Cutting experiments on Cl ranunculoides and Cl montana 'Vera' indicated that Cl montana 'Vera' had higher rooting rate than Cl ranunculoides .Sand was the better cutting medium than perlite. The number of roots per cutting treated by NAA or IBA was more than comparison. Analysis of cultural soil showed that most of Clematis can grow very well in approach acid soil.
