【目的】研究蝴蝶兰Phalaenopsis倍性与主要性状的相关性．【方法】采用压片法对85份蝴蝶兰资源的倍性进行了鉴定，测量了这些资源的气孔长度、气孔密度、叶长、叶宽、叶厚、花朵直径和花朵数．【结果和结论】85份蝴蝶兰资源中3份为二倍体，占3.5％；9份为三倍体，占10.6％；73份为四倍体，占85.9％．四倍体蝴蝶兰的气孔长度和花朵直径显著大于二倍体和三倍体，而气孔密度和花朵数显著少于二倍体和三倍体（P＜0.05）．三倍体蝴蝶兰的气孔长度、花朵直径和花朵数与二倍体蝴蝶兰差异均不显著（P＞0.05），但气孔密度显著小于二倍体（P＜0.05）．四倍体蝴蝶兰的叶长显著大于二倍体（P＜0.05），但二倍体与三倍体、三倍体与四倍体在叶长上差异不显著（P＞0.05）．二倍体、三倍体和四倍体在叶宽和叶厚上差异均不显著（P＞0.05）．蝴蝶兰倍性与气孔长度、叶长和花朵直径呈极显著的正相关关系，与气孔密度和花朵数呈极显著的负相关关系．

Objective To research the correlation between ploidy levels and main characters in Phalaenop-sis.[Method]Ploidy levels of 85 Phalaenopsis accessions were identified by using squash method , and the length and density of stoma , the length , width and thickness of leaf , the diameter and the number of flow-ers were also measured .[Result and conclusion]The results showed that in the 85 accessions there were three diploids (3.5%), nine triploids (10.6%) and 73 tetraploids (85.9%).Stomatal lengths and the length of tetraploid flower were obviously longer than those of diploid and triploid flower , while the density of stoma and the number of flowers were fewer than that of diploid and triploid (P<0.05).The differences of the stomatal cell length and diameter and the number of flower between diploid and triploid were not sig -nificant at 5%level, however, the stomatal density of triploid was less than that of diploid (P<0.05).The leaf length of tetraploid was significantly longer than that of diploid (P<0.05), while the difference of leaf length between diploid and triploid or between triploid and tetraploid was not significant ( P>0.05 ) .The difference of leaf width and thickness among diploid , triploid and teraploid were also not significant either ( P>0.05) .The ploidy levels were , to a large extant , positively associated to stomata length , leaf length and flower diameter , but negatively correlated with stomatal density and the number of flowers .
