摘　　要：以天竺葵大草原和大力水手两个系列7个品种的无性系插穗为试验材料,观测其幼苗期、生长期、孕蕾期、初花期和盛花期的株高、冠幅、茎粗、叶片数、分枝、花蕾、花梗、花瓣等植物学形态指标。依据其长势、株型和花量等形态指标判断天竺葵7个品种的性状表现。结果表明:在相同生长环境条件下,天竺葵无性系各品种之间存在差异性。在不同的生长阶段,无性系品种间观赏性状表现不同,表现优良的品种依次为“正红”、“紫红色”、“红色”、“粉色飞溅”和“浅鲑红”。The cuttings of 7 varieties of Pelargonium prairie and popeye series were used as experimental materials.The plant height,crown width,stem diameter,leaf number,branches,flower buds,pedicels and petals were observed at seedling stage,growth stage,pregnancy bud stage,first flowering stage and full flowering stage.The characters of 7 Pelargonium varieties were judged according to their growth vigor,plant type and flower number.The results show that:In the same growth environment,there were differences among varieties of Pelargonium clones.At different growth stages,the ornamental characters of clones were different,the excellent varieties were“Zhenghong”,“purplish red”,“red”,“pink splash”and“light salmon red”.
