Propagation Techniques of Slash and Loblolly Pine by Cuttings

Research on the propagation techniques of slash and loblolly pine by cuttings had been carried out for 3 years. The best propagation techniques are as follows;using medium size sand soil as medium,collecting the juvenile semi-woody cuttings, they were treated with rooting powder No.1 (low concentration) for slash pine and No.1 and No.2 (medium Concentration) for loblolly pine. The mist chamber should be used for raising rooting %. The rooting % may reach 95%. The height of 1-year old cuttings of slash and loblolly pine are 39~45cm with well developed root system. In comparison with the seedlings, the cost of the cutting is 2%~52% higher than that of the seedlings.
