Abstract:
To understa nd the rela tionship betw een the accumulation of isof lav one co ntent andg eo graphical condi tio ns, 7 soybea n va rieties w ith dif ferent isof lav one lev el w ere plantedin 7 locatio ns and the soybean iso flavo ne co ntents in the seed w ere determinated byHPLC. The result s show ed tha t the av erag e to tal i sof lav one co ntents w ere sig ni ficantdi fferent in 7 locations, the highest content ( 2492. 3μg /g ) w as show ed in Shanxi, thelow est ( 763. 4μg /g) w as show ed in Hubei. Coefficient o f v ariabi li ty o f the same v arietyva ried markedly in di fferent locatio ns. Coef ficient of v ariability of Jilin No. 3 w as thehighest ( 49. 4% ) , that of Zhang jiako u Heido u w as the lowest ( 33. 5% ) . We draw aconclusio n of tha t there exi sted highly sig ni ficant posi tiv e co rrela tion o f i sof lav o ne contentwi th lati tude, and po sitiv e cor relation w ith sea level elev atio n, but neg ativ e co rrelationwiht longi tude. Mo reov er, there were nega tiv e co rrela tio n of i sof lav one contentw ith mean temperature a nd amount of precipitatio n; po sitiv e co rrelatio n o f i sof lav o necontent w ith ho urs of sunshine. And the coef ficient of co rrelatio n wi th mean temperaturew as the highest ( r= - 0. 879* * ) .
