摘　　要：地枫皮(Illicium difengpi K.I.B.et K.I.M.)为喀斯特特有植物,其叶形、叶色,特别是嫩叶与成熟叶片颜色差异大,是很好的药用和观赏兼用型植物资源。构建观叶型地枫皮优良种质评价体系,选育出一批性状优良、观赏价值较高的优良单株,为地枫皮的良种选育和园林利用提供理论依据和优质种源。采用试验地现场调查测量与层次分析相结合的方法,从植物生长量、叶片生长量、叶片观赏性3个方面,选择15个评价指标对226株地枫皮进行统计分析。结果表明:综合评价指标权重较高的因子为嫩叶颜色(W_(i)=0.295)、叶形(W_(i)=0.140)与叶片光泽度(W_(i)=0.105);进行评价的226株地枫皮可分为5个等级,综合得分最高的20株Ⅰ级地枫皮所得分数介于3.6064~3.9442之间,突出特点表现在其嫩叶颜色较为鲜红,观赏性较高,可作为优良种质筛选标准,优先用于园林景观营造中。结合权重计算结果,观察地枫皮嫩叶颜色的变化过程、周期,以及与成熟叶片叶形的差异,认为地枫皮的嫩叶颜色是优良种质筛选的重要指标。Illicium difengpi is a unique plant in karst area.The leaf shape,leaf color,especially the color difference between tender leaf and mature leaf are obvious.It is a good medicinal and ornamental plant resource.The objective is to establish a germplasm evaluation system of foliage type Illicium difengpi,and to select a number of fine individual plants with good characters and ornamental value,so as to provide a theoretical basis and the high quality provenance for selective breeding and the landscape utilization of Illicium difengpi.This study adopted the method of combining the field survey and analytic hierarchy process,selected 15 evaluation indexes from 3 aspects,namely plant growth,leaf growth and leaf ornamental,so as to conduct statistical analysis of 226 Illicium difengpi plants.The results showed that the factors with higher weight of comprehensive evaluation indexes were tender leaf color,leaf shape and glossiness.The weight values were 0.295,0.140 and 0.105.The 226 Illicium difengpi could be classified into 5 grades.The score of 20 plants with the highest comprehensive score ranged from 3.6064 to 3.9442,which was characterized by its bright red color and high ornamental value.They could be used as a good germplasm selection standard,and could be used in landscape construction first.Combined with the weight calculation results,the change process and color cycle of the tender leaves and the differences of the leaf shape of the mature leaves were observed.It was considered that the color of the tender leaves and leaf shape of Illicium difengpi were important indicators for the selection of germplasm.
