摘要
通过嫁接繁殖栽培试验,对广东红花荷属植物花期、花序和花瓣大小、花瓣颜色进行调查,结果表明:广东红花荷属植物产地和各无性系间的花期、花序和花瓣大小、花瓣颜色差异较大,总花期为11月下旬至翌年4月下旬,延续时间可达123 d,盛花期为2月;花序平均长4.2 cm、宽5 cm,花瓣颜色多样、平均19片,根据花瓣的长宽比,可分为狭倒披针形、倒披针形、匙形、宽匙形四大类型。聚类分析揭示红花荷属植物可分为小花型组、中等花型组和大花型组共7个类型,即小花深红型、小花短瓣型、早花窄瓣型、中等花型、早花桃红型、大花长瓣型、大花圆瓣型。
To get a comprehensive understanding of Rhodoleia plants in Guangdong province,a systemic investigation was conducted on morphological structure and flowering habit of Rhodoleia plants derived from grafting.Significant differences in florescence,inflorescence size,petal size and petal colour were observed among various clones and among different origins.The entire florescence ranged from the third 10 days of November to the third 10 days of next April,totaling up to 123 days.The full-bloom occurred in February.Inflorescence has an average length of 4.2 cm,and an average width of 5.0 cm.Petal displayed a variety of color and its average number was 19.According to the ratio of petal＇s length to width,Rhodoleia flowers were divided into four types： narrow inverted lanceolate shape,inverted lanceolate shape,spoon shape and wide spoon shape.Cluster analysis classified Rhodoleia into three groups,that was small flowers,middle flowers and big flowers,and subdivided it into seven types： dark red small flowers,small flowers with short petal,early flowers with narrow petals,middle flowers,pink early flowers,big flowers with long petals and big flowers with round petals.
