Abstract:
In order to screen out the suitable conditions and methods for hard cutting of Cyclocarya paliurus.Hardwood shoots from 3-year-old Cyclocarya paliurus tree were taken as cutting materials,1/3 perlite+1/3 vermiculite+1/3 sand were taken as cutting matrix and the untreated cuttings as control.The effects of different concentrations of ABT1,ABT2 and specific rooting powder were studied,and the changes of IAAO,PPO and POD activities were analyzed.The results showed that the growth regulator treatment could increase the rate of rooting of Cyclocarya paliurus cuttings,in which,the survival rate treated with 200 mg?L-1 ABT2 was the highest,which reached to 78%;treated with 200 mg?L-1 ABT2,the activity of IAAO and PPO showed a trend of ‘rise-descend-rise-descend’,and the activity of POD showed a trend of ‘rise-descend-rise’.And the change trend was obvious compared with the control.The average rooting cycle was about 5 days ahead of time.
