Title: Effects of Different Concentrations of IBA Treatments on the Hydroponics of Ornamental Chrysanthemum
Abstract: [Objective] The study was to provide reference for simple breeding of chrysanthemum.[Method] The strong shoots of chrysanthemum in different growth period were taken,the cuttings were cultured by hydroponics after being disinfected by potassium permanganate solution and treated by indole-3 butyrate,the growth conditions of cuttings after treatment was studied.[Result] The whole survival rate of cuttings that taken on April 20 was 61% higher than that of taken on April 9.The survival rate of cuttings that were disinfected was 30% higher than that of non-disinfection,The cuttings treated by 200 ppm IBA for 12h on April 9 were all dead,and the survival rate of cuttings that treated by 100 ppm IBA for 12h was also lower,The survival rate of cuttings treated by the same hormone for 6h on April 20 was increased significantly.The root number of cuttings treated by 100 ppm IBA was obviously higher than that of other treatment groups,treated by 200 ppm IBA was slightly higher than that of non-hormone treatment ones.[Conclusion] The survival rate of cuttings could be increased when cuttings were taken in the last ten-day of April and treated by 100 ppm IBA after being disinfected.
