摘要
【目的】分析黑龙江省4种野生百合不同器官矿质元素含量的差异特征,探究不同野生百合种质资源全株利用价值,为后续野生百合的品种选育和全株综合利用提供理论依据。【方法】采用火焰原子吸收光谱法,对黑龙江省细叶百合、东北百合、有斑百合和毛百合4种野生百合根、茎、叶和鳞茎的矿质元素(K、Ca、Na、Mg、Cu、Zn、Mn、Fe、Pb和P)含量进行测定,探究4种野生百合不同器官之间矿质元素的差异及其相关性,并利用主成分分析和聚类分析对其利用价值进行综合评价。【结果】4种野生百合矿质元素含量丰富,鳞茎矿质元素平均含量的大小排序为K>Mg>P>Ca>Na>Fe>Zn>Cu>Mn>Pb,根为K>Na>Mg>P>Ca>Fe>Zn>Cu>Mn>Pb,茎为K>Mg>Ca>P>Na>Fe>Cu>Zn>Mn>Pb,叶为K>Ca>Mg>P>Na>Fe>Zn>Cu>Mn>Pb。不同百合品种之间矿质元素含量分布呈现出不同的规律,其中细叶百合和东北百合4种器官中的P含量显著高于有斑百合和毛百合(P<0.05),有斑百合和毛百合4种器官中则含有更丰富的Cu元素;4种器官中,茎和叶的K/Na值较高,而鳞茎和根中则较低。4种百合中,毛百合各器官中的K/Na值均最高。各器官中矿质元素含量的相关性存在较大差异,鳞茎中,Pb与Mg和K、Fe与Ca和P、K与Mg元素之间呈极显著性正相关(P<0.01),Cu与Fe和Ca之间呈极显著负相关(P<0.01);根中,Ca与Fe、K与Mn、Zn与Mg之间呈极显著正相关性(P<0.01),Fe与Pb、Cu与Zn和Mg、Ca与Pb之间均呈极显著负相关(P<0.01);茎中,Fe与Na、P与K之间呈极显著正相关(P<0.01),Mn与Ca、Pb与Na和Fe之间呈极显著负相关(P<0.01);叶中,Mg与Pb、Fe与Na之间呈极显著正相关(P<0.01)。在鳞茎和叶中,Mn元素与其他元素相关性较低且均不显著。主成分分析发现,黑龙江省4种野生百合的代表性元素为P、K、Mn,选取其中前3个主成分(F_1~F_3)进行综合排名,综合评价得分由高到低分别是细叶百合、东北百合、有斑百合、毛百合。聚
【Objective】In this study,the differences in mineral element contents in different organs of four wild lily verities in Heilongjiang were analyzed and the whole plant utilization values of different germplasm resources were explored to provide basis for breeding wild lily varieties and comprehensive utilization of entire plants.【Method】Four wild lily varieties in Heilongjiang,namely Lilium pumilum,L.distichum,L.concolor var.pulchellum and L.pensylvanicum,were selected and mineral element contents(K,Ca,Na,Mg,Cu,Zn,Mn,Fe,Pb and P)in roots,bulbs,stems and leaves were determined by flame atomic absorption spectroscopy.The differences and correlations of mineral elements among different organs of four wild lilies were explored.Then,the principal component analysis and cluster analysis were also used to comprehensively evaluate their utilization values.【Result】The four wild lily verities were abundant in mineral elements and contents of bulb mineral elements were in order of K>Mg>P>Ca>Na>Fe>Zn>Cu>Mn>Pb.The mineral element contents in roots were in order of K>Na>Mg>P>Ca>Fe>Zn>Cu>Mn>Pb,those in stems were in order of K>Mg>Ca>P>Na>Fe>Cu>Zn>Mn>Pb,and those in leaves were in order of K>Ca>Mg>P>Na>Fe>Zn>Cu>Mn>Pb.The distribution of mineral element contents was different among different varieties,with significantly higher P contents in organs of L.pumilum and L.distichum(P<0.05)and more abundant Cu contents in organs of L.concolor var.pulchellum and L.pensylvanicum.The K/Na ratio was higher in stems and leaves than in bulbs and roots,and L.pensylvanicum had the highest K/Na values in all organs.The correlations of mineral element contents were greatly different among organs.There were very significantly positive correlations for Pb-Mg,Pb-K,Fe-Ca,Fe-P and K-Mg(P<0.01)and very significantly negative correlations for Fe-Cu and Cu-Ca(P<0.01)in bulbs.Ca-Fe,K-Mn and Zn-Mg in roots demonstrated very significantly positive correlations(P<0.01),while Fe-Pb,Cu-Zn,Cu-Mg and Ca-Pb in roots showed very significant negative corr
