摘  要:
测试了沙生冰草(Agropyroncristatum deseotorum)、无芒雀麦(Bfomus ynermis)不同株龄的细胞壁、细胞内容物含量。沙生冰草细胞壁含量(y)与株龄(x)(半月龄,下同)间呈非常显著正相关(r=0.8609 P<0.01),其线性回归方程式为:y=48.45+1.91x(P<0.01 r~2=0.74),其细胞内容物含量(y)与株龄(x)间呈非常显著负相关(r=-0.8586 P<0.01).其线性回归方程式为:y=37.67-1.78x(P<0.01 r~2=0.74)。无芒雀麦细胞壁含量(y)与株龄(x)间呈显著正相关(r=0.6768 P<0.05),其线性回归方程式为:y=53.88+0.83x(P<0.05 r~2=0.46),其细胞内容物含量(y)与株龄(x)问呈非常显著负相关(r=-0.9524 p<0.01),其线性回归方程式为:y=33.80-1.27x(P<0.01 r~2=0.91)。用株龄变量估测了酸性洗涤纤维、纤维素、木质素、粗蛋白、初水分含量的回归方程式。

摘  要:
Data analyses indicated that cell wall constituent of Agropyron deseotorum(Y)with age in half months (X)showed a significant positive correlation(r=0.8609 P<0.01),the regression equation is Y=48.45 +1.91×(P<0.01 r~2=0.74).The cellular content of Agropgron deseotorum(Y)with age in half months (X)showed a significant negative correlation(r=-0.8586 P<0.01),the regression equation is Y= 37.67-1.78×(P<0.01 r~2=0.74) .The cell wall constituent of Bromus inermis(Y)with age in half months(X)showed a singnificant positive correlation(r=0.6768 P<0.05),the regression equation is Y=53.88+0.83x(P<0.05 r~2=0.46),The cellular content of Bromus inermis(Y)with age in half months(X)showed a significant negative correlation(r=-0.9524 P<0.01),the regression equation is Y=33.80-1.27×(P<0.01 r=0.91).This paper also reported the regression equations which es- timate ADF,ADL,CP,cellulose and dampness.
