摘要：

摘要：本文采用主成分分析法,对外源镧协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；其它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个协迫效应的主成分，累积方差贡献率为93.92%。根据主成分对原性状的综合能力，进行微生素系例分析，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+0.4613F6-0.4947F7 y2=0.6392F1-0.4636F2+0.3622F3-0.3004F5+0.3443F5+0.1855F6-0.0462F7 y3=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，所以为较适宜的协迫浓度。

Abstract:

Abstract：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% has 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 the equation of main components were as follows: y1=0.4112F1+ 0.4351F2-0.4057F3-0.3929F4+0.0270F5+ 0.4013F6+ 0.4013F7 y2=0.2931F1-0.2431F2+00.2940F3+0.3314F4+0.7175F5+0.2683F6+ 0.2683F7 y3=-0.1200F1-0.0483F2+0.3448F3+0.3341F4+-0.5962F5+0.4456F6+ 0.4456F7 The 40mg/Kg treatment had the highest principle components and integrate scores and it was the relatively suitable concentration.
