摘要: Multivariate relationships in and statistical moments of eight biochemical constituents their impact on estimating carbon/nitrogen (C/N) ratio alfalfa, corn, soybean, cuphea, switchgrass residues indicate that (1) equal portions variation C/N were explained by differences among crops organs; however, the largest variations N C organs within crops, respectively; (2) N, but not or + C, content greatest variance ratios; (3) biochemically, stems closer to roots than leaves; hence large portion leaves (R2 = 61.0%) only 58.0%); (4) moments, other mean values constituents, significantly impacted estimates reliability these estimates, both which positively correlated (r 0.64, p < 0.001).
