摘要
以湖北大悟、湖南武冈、湖南浏阳实地收集的13份野生黄栀子为研究对象,采用层次分析法,建立了包括1个目标层、4个约束层和16个标准层的13份野生黄栀子观赏价值的评价模型,并对13份野生黄栀子进行了观赏价值的综合评价。结果表明:在黄栀子的16个评价指标中,以花型的权重值最大,其次为单季花量,再次为花香、花冠大小,其权重值分别为0.250、0.132、0.117和0.099,因此,花型好、花量大、香味浓郁、花冠长是黄栀子观赏价值的重要评价指标;根据综合得分结果,在13份野生黄栀子中,野生黄栀子资源1、4、9和13号的等级为Ⅰ级,野生黄栀子资源2、3、6、11和12号的等级为Ⅱ级,这9份野生黄栀子资源整体性状表现优良,花型好、花量大、开花期长,可在乡村旅游中作为观赏品种推广,其中野生黄栀子资源1号为梅花花型、花型独特,4号的开花天数最长、观赏期久,13号的株型好、抗性最强。
Using 13 wild Gardenia jasminoides accessions collected from Dawu of Hubei Province,and Wugang and Liuyang of Hunan Province as tested objects,an ornamental value comprehensive evaluation system of Gardenia jasminoides,including one target layer,four constraint layers and 16 criterion layers,was constructed by the application of analytic hierarchy process(AHP)to screen out excellent Gardenia jasminoides varieties with high ornamental value and strong adaptability for wide promotion.The results showed that,among 16 indicators,flower type possessed the largest weight,followed by the flower amount per season,and then floral fragrance and corolla diameter whose weight values were 0.250,0.132,0.117 and 0.099,respectively.Therefore,flower type(good),flower numbers(great),fragrance(rich)and corolla diameter(large)are important evaluation indexes of ornamental value of Gardenia jasminoides.According to the results of comprehensive evaluation,accessions 1,4,9 and 13 ranked gradeⅠ(>3.0),and accessions 2,3,6,11 and 12 ranked gradeⅡ(2.5-3.0);these nine wild gardenia resources have excellent overall characteristics,good flower type,large quantities of flowers and long flowering period,which can be promoted as ornamental varieties in rural tourism.Particularly,accession 1 shapes like plum blossoms,rather unique;while accession 4 has a longest flowering period and a long ornamental period,and accession 13 has a good plant type and strongest resistances.
