BACKGROUND:There is no mention in the literature of vegetative propagation of Vaccinium myrtillus. OBJECTIVE:The aim of the study was to evaluate the rooting potential of bilberry rhizome and stem cuttings. METHODS:Rhizome and stem cuttings collected in early Autumn were dipped in different IBA solutions (0 – 2000 – 4000 mgL–1) and rooted in non-sterilized V. myrtillus soil and expanded perlite under controlled growth chamber environment or under mist with basal heating in a greenhouse for 12 weeks. RESULTS:Rhizome cuttings showed high rooting potential in plant growth regulator (PGR) free substrates. Conversely, stem cuttings took advantage from IBA treatments; this positive effect on rooting percentage was synergistically increased when rooted in agriperlite. A higher rooting capacity was achieved when rhizome and stem cuttings were placed in agriperlite, however number of developed roots and shoots were much higher when V. myrtillus turf was used as substrate. Mist and bottom heating did not improve rooting significantly. CONCLUSIONS:V. myrtillus can be successfully propagated both by rhizome and stem cuttings. With an overall rooting success of 56–68% and with a reasonably good growth rate, production of planting material from stem cuttings of V. myrtillus offers opportunities for a cheaper, practically feasible and technically less demanding alternative means of propagation.

不同环境条件下托斯卡纳牛痘苗茎和根茎插条的不定根

背景：在文献中没有提到牛痘越桔的营养繁殖。目的：本研究旨在评估越橘根茎和茎条的生根潜力。方法：将秋初收集的根茎和茎插条浸入不同的IBA溶液（0 – 2000 – 4000 mgL–1）中，扎根于未灭菌的肉豆蔻土壤和膨胀珍珠岩中，在受控的生长室环境中或在基础加热的雾中在温室中放置12周。结果：根茎插条在无植物生长调节剂（PGR）的基质中显示出高的生根潜力。相反，茎cutting插则利用IBA处理。当扎根于磨刀石时，对生根率的正面影响会协同增加。将根茎和茎条插在aperperlite中可获得更高的生根能力，但是当使用Myrtillus草皮作为基质时，发达的根和芽的数量要高得多。薄雾和底部加热不能显着改善生根。结论：V．可以通过根茎和茎插枝成功繁殖肉豆蔻。总的生根率达到56％至68％，并且生长速度相当好，利用肉毒杆菌的插条生产种植材料为廉价，实用和技术要求较低的替代繁殖方式提供了机会。可以通过根茎和茎插枝成功繁殖肉豆蔻。总的生根率达到56％至68％，并且生长速度相当好，利用肉毒杆菌的插条生产种植材料为廉价，实用和技术要求较低的替代繁殖方式提供了机会。可以通过根茎和茎插枝成功繁殖肉豆蔻。总的生根率达到56％至68％，并且生长速度相当好，利用肉毒杆菌的插条生产种植材料为廉价，实用和技术要求较低的替代繁殖方式提供了机会。
