Rooting Greenwood Tip Cuttings of a Difficult-to-Root Populus Clone

Many Populus hybrids show promise for highly productive forest plantations because of their rapid early growth and high yield. Clones are propagated vegetatively to retain their desirable genetic characteristics (2,3). One very promising clone is a Populus alba L. x P. grandidentata Michx. hybrid (Crandon). Once established, it grows rapidly and produces wood with excellent fiber qualities. However, often less than 50 percent of the cuttings root, making it difficult to establish successful plantings. Elevated bed temperatures and treatment with rooting hormones are known to favor the rooting of many difficult-to-root species (5). Hormones have been found to stimulate rooting of both dormant stem cuttings (7) and greenwood cuttings (1,4) of some Populus. So we tested the effects of various temperatures and hormone concentrations on rooting performance of Crandon greenwood branch tip cuttings.
