种子质量标准的确定方法研究

Studies on Methods of Determining Seed Quality Standard

该文提出了种子质量标准的试验与分析方法,研究了试验观测值的数学模型,引进了“本真值”新概念,创立了以本真值为标准尺度的标准值计算方法。品仲纯度标准值(CPSV)等于纯度试验平均值(c)与纯度试验标准误(Sec)之差,即:CPSV=c-Sec;种子净度标准值(SPSV)等于净度试验平均值(s)与净度试验标准误(Ses)之差,SPSV=s-Ses;发芽率标准值(GPSV)等于发芽试验平均值(g)与发芽试验标准误(Seg)之差,GPSV=g-Seg;水分标准值(MCSV)等于水分试验平均值(m)与水分试验标准误(Sem)之和,MCSV=m+Sem。

Methods of experiment and analysis of seed quality standard were produced, And studies on mathematical model of observed value were done. A new concept of ' Native Value' was introduced. The calculating method of standard value was originated with native value being standard scale. Cultivar purity standard value (CPSV) equals experimental means of cultivar purity (Xc) minus standard erro (Sec), i. e. CPSV=Xc -Sect Seed purity standard value (SPSV)equals experimental means of seed puity (Xs)minus standard erro(Ses). i. e. SPSV = Xs -Ses;Germination percentage standard value (GPSV) equals experimental means of germination percentage (Xg) minus standard erro (Seg). i, e. GPSV = Xg -Seg; Moisture content standard value (MCSV) equals experimental means of moisture content (Xm) plus standard erro (Sem). i. e. MCSV = Xmm + Sem.
