Title: Research on technology of hardwood cutting propagation of Sabina przewalskii
Abstract: The purpose of the study was to investigate the techniques of cutting propagation and physiological and biochemical basis for Sabina przewalskii.By cutting method in auto-interval mist system,together with some treatments,the rooting ability of different ortet ages,different cutting length,different branches types,different plant hormones,some rooting index such as rooting ratio,rooting quantity and root length were investigated.The endogenous hormones content,including IAA,ABA,GA_3 and Z,phenol compounds and sugar compound were measured using HPLC.The result obtained by the experiment indicated that the rooting ratio of young individuals was higher than mature individuals′;The rooting ratio of hardwood was increased by plant hormone treatment,(especially) treated by IBA 500 ·kg~-1,the rooting ratio has been over 75%;The best cutting length is less than 10 cm;There is no difference of rooting ratios between branches types.The content of IAA,ABA,GA_3 and Z,phenol compounds and sugar compound as well as the ratio of IAA to ABA,IAA to Z from different cutting types are correlated with the rooting ratio.Single hormone has no obvious effect on the rooting of hardwood cutting of S.przewalskii.
