摘　　要：应用权重系数法和灰色关联度法对176份彩叶凤梨种质资源进行了观赏性评价,评价表明,其中24份资源两种方法评价观赏性均优良,可供生产上直接利用;两种方法都能较好地评价彩叶凤梨的观赏性,两法评价的相关系数为0.896 7**。相比较,权重系数法受主观影响大些,计算简单,但权重系数确定较繁琐;灰色关联度法比较客观,实用性较强。如结合两法的长处,采用加权关联度法,评价应更为合理。Weighting coefficient method and grey correlation method were used to evaluate ornamental characteristics of 176 Neoreglia germplasm resources. Results showed that 24 resources were evaluated as excellent by both two methods, and could directly prepare for production. Both two methods could suitably evaluate the ornamental characteristics of Neoreglia germplasm resources, and correlation coefficient between the two methods was 0.896 7＊＊. Weighting coefficient method was relatively more subjective, with more simple calculation but complicated weight coefficient determination. Grey correlation method was more objective and stronger practicability. The evaluation results should be more reasonable if we combine the two methods as weight relation method.
