| Research Abstract |
We investigated effects of warming the basal ends of woody-plant cuttings at controlled low-air-temperature on their root growth and consequent growth after planting. Root development was greater and leaf damage evaluated with intensities of necrosis was less in the warmed Carolina-poplar leafy-cuttings than in control cuttings which was planted without the treatment. When the warming treatment was applied to cuttings with dormant terminal bud during low temperature storage, The both rooting and sprouting was improved in warmed cuttings, whereas the only rooting or spouting was improved was improved in non-stored or non-warmed cuttings, respectively. The warming technology would improve the cutting propagation of woody plants, because it would ensure that the cuttings are ready to develop roots with a minimum loss of carbohydrates, regardless of the weather.
