Abstract:
Different Taxus branches were selected as test materials,using the L9(34) orthogonal test method,9 combinations of cuttage propagation of Taxus cuspidata were carried out in greenhouse.Each combination was repeated 3 times with 50 cuttings,and the rooting rate was investigated and analyzed.The effects of the age of cuttings,the concentration of ABT1,and the length of soaking time on the rooting rate were analyzed and discussed.Moreover,the best combination for cuttings propagation of yew was obtained.The results showed that the rooting rate of T.cuspidata was significantly influenced by the age of cuttings and the length of soaking time,while the concentration of ABT1 had no significant effect.In addition,the program A1B3C3 had the highest rooting rate,and the rooting rate of A3B1C3 was nearly to A1B3C3.In details,the same one-year branch (C3),higher rooting rate could be obtained at lower concentration ABT1 (A1,50 mg?L-1) for longer time (B3,4.0 hours) or at higher concentration ABT1 (A3,500 mg?L-1) for shorter time (B1,0.5 hour) (rooting rate about 96%).The results indicated that with lower concentration ABT1,the treating time was longer,while with higher concentration ABT1,the treating time was shorter.Moreover,the combination A1B3C3 was used in Taxus chinensis var.mairei and Taxus×media,and the rooting rates of both yew reached more than 90%.The technology of cuttage propagation established by this research was simple and easy to use,and could be used for reference for other species of yew cuttage breeding in greenhouse.
