本试验以燕麦种子为材料,用四唑染色法、红墨水染色法和靛蓝染色法测定其生活力,用土壤发芽法测定发芽率,得出其生活力(X)与发芽率(Y)之间的关系式分别为: Y_(四唑)=0.069x~(1.58)(r=0.9934),Y_(红墨水)=0.193x~(1.35)(r=0.9905), Y_(靛兰)=0.088x~(1.52)(r=0.9922)。应用这些公式可在已知生活力的情况下,计算出相应的发芽率。 In this experiment, oat seeds were used as materials, and their viability was determined by tetrazolium staining, red ink staining and indigo staining. The germination rate was determined by soil germination method, and its viability (X) and germination rate (Y) (Tetrazolium) = 0.069x ~ (1.58) (r = 0.9934), Y_ (red ink) = 0.193x ~ (1.35) (r = 0.9905), Y_ x ~ (1.52) (r = 0.9922). Apply these formulas to calculate the corresponding germination rate given the known viability.
