Abstract: Photinia frasery , a new and superior variety with colored leaves , has been successfully introduced from other countries in recent years .The long duration of rooting after cuttage and low rooting rate make its propagation on a large scale difficult .In the multi-factor experiment designed in the paper , effects of different culture solutions and different concentrations of three growth regulating substances (self-prepared rooting agent , NAA and ABT)on the rooting of water cultured hardwood cuttings of Photinia frasery .are studied to find out the best rooting conditions .The results show that the roots are of callus type and rooting rate is significantly influenced by different culture solutions and different concentrations of hormones .Among all the combined conditions , pure water +0 mgL-1 self-made rooting agent 1 , pure water + 5 mgL-1 ABT , and nutritive solution + 10 mgL-1 self-made rooting agent have good effect on rooting , rooting rates in these conditions being 100 %, 93.3 % and 91.7 %, respectively .Suggestions have been made on how to adjust culture solutions , how to increase the concentration of growth hormones and selection of growth hormones at different stages of culture .[ Ch , 4 tab.8 ref.]
