Abstract:
In this paper,studies were made of effects of different indolebutyric acid concentrations (being 100,500 and 1 000 mg·L
-1 respectively) and imposed time (being 1/3 h,2 h and 12h respectively) on the rooting of hardwood cuttings in Figs (
Ficus carica L.),ainaing to explore the most effective ways to make cuttings root quickly.One year old branches from three fig cultivars-BoJiHong,JinAoFen and B110 were used as experimental materials.The experiment was carried out in the orchard in Science Research Institute of Fig and Walnut,by use of completely randomized block experimental design.Thd data began to be collected on the 12th days after cutting,including callus formation,rooting rate,average root number and average root length.The results showed that the best treatment was 500 mg·L
-1 indolebutyric acid and two-hour imposed time.As compared with control,the callus formation time of this treatment was seven days earlier,the rooting rate increased by 13.3%,average root number increased 28.9,and average root length was 2.1 cm longer; there existed significant differences among cultivars for the aspect of rooting ability,the rooting ability of JinAoFen was the best,BoJiHong took the second place,and B110 was the worst.
