Pistacia chinensis which is native to Taiwan having finely divided and dark green foliage, bright red fruit ripening to dark blue make it an outstanding ornamental shade tree. Clonal propagation would selection of cultivars having desirable characteristics.
Propagation of Pistacis chinensis stockplant by mound layering. Wound the base of the shoot is necessary for root production. Another object of this study was to determine the advantageous time to collect cuttings. Stem cuttings were taken from July 2006 to March 2007. Rooting was unsuccessful except when cuttings were taken in July. The greatest percentage of rooting is 43.3% in July and the lowest is 0% in January. The effects of cutting position within the source shoot on rooting were assessed. Stem cuttings were taken from terminal or basal positions of the shoots. Terminal cuttings exhibited higher rooting (20%) and survival (36.7%) than basal ones rooting (5%) and survival (13.3%). The bases of the cuttings were treated with IBA. Percent rooting was not significantly affected by concentration of IBA. When propagation by hardwood cuttings, the bases of the cuttings were swelling and a period time passed they died. The one feature of the radish seed bioassay of chromatographed bark extracts was a inhibition of germination on the chromatograph strips.
