Effect of Different Concentration Rooting Solution on Rooting Rate of Olive Cuttings

The rooting rate of olive cuttings of Frantoio and E'zhi varieties was studied by immersing them in rooting solution with concentration of 0 mg·L^-1, 100 mg·L^-1, 200 mg·L^-1, 300 mg·L^-1 and 400 mg·L^-1, respectively. The results showed that the cuttings without rooting solution had little callus and hardly rooted.The rooting rate of Frantoio was 3%, 37%, 42%, 76%, 63% in rooting solution of 0 mg·L^-1, 100 mg·L^-1, 200 mg·L^-1, 200 mg·L^-1, 300 mg·L^-1 and 400 mg·L^-1, respectively. The rooting rate of E'zhi was 2%, 21.25%, 40.5%, 70.25% and 53.13% in rooting solution of 0 mg·L^-1, 100 mg·L^-1, 200 mg·L^-1, 300 mg·L^-1 and 400 mg·L^-1,respectively. The optimum concentration of hormones was 300 mg·L^-1 in rooting solution of Olive cuttings.
