[Study on propagation technology of Acanthopanax trifoliatus by cuttings].

ABSTRACT

OBJECTIVE: In order to obtain substantial clonal plants, we studied the cuttings propagation technology. METHODS: The cutting roots and stems of Acanthopanax trifoliatus were used as plant materials, and different materias, seasons and other conditions for cutting propagation were tested. RESULTS: It showed that the survival rate of stem segments was higher than that of root segments. The test of age of plant materials found that high survival rate could be obtained from semi-lignified stem segments and the segments from the base stem could survive successfully. Autumn was more suitable for plants' survival. Moreover, the rooting rate reached 89.4% by inserting segments with leaves into sand soil after dipping into 1500 mg/L IBA for 10 s, and with plastic membrane and shading net covered. CONCLUSION: The rooting rate can increase significantly by collecting semi-lignified basal stems in autumn, cutting them for leaf cuttings, and inserting them into sand soil after dipping into 1500 mg/L IBA for 10 s.
