Abstract:
Taking the pot of red Catharanthus roseus (L.) G.Don as experimental materials，the effects of hormone treatments and position of cuttings on adventitious root development from the cuttings were studied.The results showed that when using single hormone NAA，IBA or ABT-6 for the treatments，50 mg/L ABT-6 had the best rooting effects，whose average rooting rate，average root number and average root length was 63.70%，4.31 number and 1.27 cm respectively.The 9 h treatment was the best when using 50 mg/L ABT-6 solution for different processing times.Its average rooting rate，average root number and average root length was 82.96%，6.61 number and 2.40 cm respectively.The best two-hormone combination for rooting effect was ABT-6 50 mg/L+NAA 15 mg/L.Its average survival rate，average root number and average root length reached 100%，11.76 number and 4.68 cm respectively.The cuttings effect was the central position＞the bottom position＞the top position.And the average rooting rate，average root number and average root length of the central position was 100%，12.51 number and 5.01 cm respectively.
