A fundamental study of the high-performance woody-plant propagation system based on the environmental responses

本文研究了在控制低温条件下对木本植物扦插根端进行加热处理对其根系生长和植后生长的影响。与未处理的对照扦插相比，处理后的卡罗莱纳杨扦插根系发育更大，叶片损伤程度以坏死强度评价的程度更小。低温贮藏期间对顶芽休眠的插条进行增温处理，增温处理能促进插条的生根和出芽，而未加温处理和未加温处理只促进插条的生根和出芽。升温技术将改善木本植物的扦插繁殖，因为它将确保无论天气如何，扦插都能以最小的碳水化合物损失准备好生根。

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.
