Abstract
To study the rapid growth of pear stunted rootstock,seedlings of pear stunted rootstock SPRB15 were used to follow the effects of plant growth regulators on rapid growth of the seedlings.The results showed that the increases of seedlings' diameter and height which sprayed 100 mg/L GA(4+7) twice with 7 days interval(treatment 4) were the best in this trial;next were that of sprayed GA3 100 mg/L twice(treatment 2),sprayed GA(4+7)50 mg/L twice(treatment 3),sprayed GA3 50 mg/L twice(treatment 1),and sprayed BA 250 mg/L twice(treatment 5),in order.The results indicated that GA(4+7) and GA3 had the effects of promoting the growth of pear stunted rootstock SPRB15;BA had the effect of promoting the sprouting of lateral bud.
