Abstract:
Taking Picea likiangensis var.linzhiensis as test material,effect of exogenous hormones,age of maternal plant and position on the maternal plant on the rooting process were studied.The results showed that the rooting ability of P.likiangensis var.linzhiensis was affected greatly by the types of the exogenous homornes and their concentrations,and thebest condition for rooting of this species was identified as 4 hour immersion in ABT1# with a concentration of 0.25 g/L.The age of maternal plants could affect the rooting ability of P.likiangensis var.linzhiensis,indicated by the mean root-number and the root effective index.Specifically,the rooting ability would decrease with the increasing age of maternal plant.The rooting ability of the P.likiangensis var.linzhiensis was also affected by the source position on the maternal plant,since the rooting rate,root number and the root effective index were the lowest in the cutting branches from the top and northern position of the maternal plant.The results would be of great help to the field collection and the cutting progagation of P.likiangensis var.linzhiensis.
