摘　　要：以 36个不同生态型的大白菜品种、品系为试材 ,研究了基因型对芽分化的影响 ,选出 7个具有较高芽再生频率的品种 (系 ) :36 - 6、4 3- 3、福山包头、福山大包头 (Ⅱ )、福山核桃纹、胶州小叶和济南大根。对卵圆型和直筒型大白菜二次饱和—D最优试验设计 ,得到控制不定芽分化的激素浓度模型为 :y(卵圆形 ) =0 .0 1+84 .4 8x1+2 6 .92x2 - 4 2 .2 4x21- 6 .6 9x22 +3.36x1·x2 和y(直筒型 ) =10 9.88x1+31.2 8x2 - 10 9.88x21- 7.71x22 +11.73x1·x2 (y =芽分化频率 % ,x1=NAAmg/L ,x2 =BAmg/L)。Effects of genotypes on shoot differentiation were studied and 7 varieties or lines which had high shoot differentiation frequencies were selected.Hormone combination models controlling shoot differentiation were formed through square saturated D-optimal design:y( ovata )=0.01+84.48x 1+26.92x 2-42.24x 2 1-6.69x 2 2+3.36x 1·x 2 and y( cylindrica )=109.88x 1+31.28x 2-109.88x 2 1-7.71x 2 2+11.73x 1·x 2(y=shoot differentiation frequency%,x 1=NAA mg/L,x 2=BA mg/L).
