【摘要】 以大花萱草霞光、粉红宝、金红星品种为材料,采用单芽蘸根盆栽方法,研究了NAA (300,500,800 mg·L^-1)、6-BA(100,200,400 mg·L^-1)、IBA(300,500,800 mg·L^-1)、NAA×IBA(300×300,500×500,800×800 mg·L^-1)对大花萱草分蘖能力及成活率的影响。结果表明,6-BA对大花萱草分蘖能力有着极显著的影响,6-BA 200 mg·L^-1对霞光分蘖效果最佳,增殖系数为4.67;6-BA 400 mg·L^-1对粉红宝分蘖效果最佳,增殖系数为3.11;6-BA 400 mg·L^-1对金红星分蘖效果最佳,增殖系数为2.46。且大花萱草成活率与4种植物生长调节剂有关。更多还原

【Abstract】 Taking the Hemerocallis hybrid Hort. Xiaguang, Fenhongbao, Jinhongxing as experimental material, the single bud root potting method was used to study the effect of NAA(300, 500, 800 mg·L^-1), 6-BA(100, 200, 400 mg·L^-1), IBA(300, 500, 800 mg·L^-1),NAA × IBA(300×300, 500×500, 800×800 mg·L^-1) on the tillering capacity of Hemerocallis hybrid Hort. and survival rate. The results showed that 6-BA had a significant effect on the tillering ability of Hemerocallis hybrid. Screening of 6-BA 200 mg·L^-1 had the best effect on Hemerocallis hybrid Hort. Xiaguang, the multiplication coefficient was 4.67, 6-BA 400 mg·L^-1. Hemerocallis hybrid Hort. Fenhongbao effect was the best, and the multiplication coefficient was 3.11. 6-BA 400 mg·L^-1 had the best effect on hybrid Hort. Jinhongxing, and the proliferation coefficient was 2.46. And the survival rate of hybrid Hort. was related to four plant growth regulators.更多还原
