添加外源镧条件下姬松茸中微生素的相关性及主成分分析

Correlation and Principle Components Analysis on the Agaricus blazei MURILL Vitamin under the Condition of Exogenous Addition of Selenium

采用主成分分析法,对外源镧胁迫姬松茸的效应进行了研究。结果表明,姬松茸的维生素B6与烟酰胺和B2呈极显著和显著负相关;烟酰胺与B2呈显著正相关;叶酸与B2呈显著负相关;其他性状间的相关均为负或正相关。从7项微生素指标中提取出3个胁迫效应的主成分,累积方差贡献率为93.92%。根据主成分对原性状的综合能力,进行微生素系列分析,3个主成分可分别解释为叶酸和B6效应因子,Vc效应因子,B5效应因子,并建立了主成分方程分别为:y1=0.1682F1+0.1542F2+0.3570F3+0.4420F4-0.4094F5+0.4613F6-0.4947F7y2=0.6392F1-0.4636F2+0.3622F3-0.3004F5+0.3443F5+0.1855F6-0.0462F7y3=0.1380F1+0.8114F2+0.3705F3-0.1821F4+0.2739F5+0.0908F6+0.2625F7各处理组的主成分得分、综合得分计算排序第一为40mg/kg处理组,所以为较适宜的胁迫浓度。

The principal components analysis was adopted to investigate the vitamin efficiency of the Agaricus blazei MURILL under the condition of exogenous addition of Se.The results showed the VC was significant positive correlated with folacin and VB2;B5 was significant negative correlated with VB6 and VB1;VB1 and VB6,folacin and VB2 were significant positive correlated;others were not significant correlated.3 main components which contributed the accumulative variance by 98.40%have been picked out from the 7 vitamin character indexes.According to the comprehensive function of each main component,the 3 main components could be explained respectively as the factor of VB5 and VC effect,the niacinamide effect and the folacin and VB2 effect.And the equation of main components was as follows：y1=0.4112F1＋0.4351F2-0.4057F3-0.3929F4＋0.0270F5＋0.4013F6＋0.4013F7y2=0.2931F1-0.2431F2＋00.2940F3＋0.3314F4＋0.7175F5＋0.2683F6＋0.2683F7y3=-0.1200F1-0.0483F2＋0.3448F3＋0.3341F4＋-0.5962F5＋0.4456F6＋0.4456F7The 40 mg/kg treatment had the highest principle components and integrates scores and it was the relatively suitable concentration.
