Abstract:The treatment of the cuttings of three colorful leafy laurel species was conducted by disinfection and dipping in the rooting agents of different concentrations of ABT1. The results showed that disinfection was an important part of culturing the cutting seedlings of osmanthus fragrans colour Group. using 1000times solution of 50% carbendazim to dis- infect the cuttings of three species of cinnamomum burmannii , the rooting rate of cuttings was significantly higher than that of the control , and the value was increased by more than 25% . The ABT1 rooting agent had extremely significant effects on the rooting rate and rooting number of 3 osmanthus varieties . The cuttings were treated with ABT1rooting a- gent at a concentration of 0. 3 mg ● L—1 , and the rooting effects of 6yun tian caigu》, 6zhenzhu caigu》, and 6yinbian caigu》were the best , and their rootingrates and number of rooting were (97. 5% , 5. 4) , (95. 0% , 5. 6) , (94. 2% , 4. 6) , respectively , for the three varieties .
