Large-fruited cranberry ( Aiton) is a species known for its highly valued fruit and is typically propagated vegetatively through the rooting of stem cuttings. Studies on the rooting of stem cuttings of large-fruited cranberry have shown that the morphological traits of the root system are a key indicator of the effectiveness of this process. To support rooting, gel coatings based on polysaccharides and containing auxins, especially the indole-3-butyric acid (IBA) W4 variant, were developed and applied. These significantly influenced root length (increase of 44.6% compared to control W0), surface area (increase of 32.4% compared to W0), volume (increase of 26.7% compared to W0), and average thickness, which translated into better nutrient uptake and a higher degree of plant nourishment. The W4 coating, combining mineral components, polysaccharides, and IBA, reduced transpiration and maintained moisture, promoting effective rooting. The associated metabolic changes were confirmed by analyses of oxidative stress markers and chlorophyll fluorescence. The study demonstrated that enhanced root system development was closely linked with the increased accumulation of macro- and micronutrients in the aerial parts of the plants, directly contributing to improved growth and potential yield. These findings highlight that effective rooting-achieved through the targeted metabolic stabilisation of the rooting environment-is essential for the successful vegetative propagation of large-fruited cranberry.
大果蔓越莓（Aiton）是一种因其高价值果实而闻名的物种，通常通过茎插条生根进行无性繁殖。对大果蔓越莓茎插条生根的研究表明，根系的形态特征是这一过程有效性的关键指标。为了支持生根，基于多糖并含有生长素，特别是吲哚 - 3 - 丁酸（IBA）W4变体的凝胶涂层被开发并应用。这些涂层显著影响了根长（与对照W0相比增加了44.6%）、表面积（与W0相比增加了32.4%）、体积（与W0相比增加了26.7%）和平均厚度，这转化为更好的养分吸收和更高的植物营养程度。结合矿物质成分、多糖和IBA的W4涂层减少了蒸腾作用并保持了水分，促进了有效生根。通过对氧化应激标记物和叶绿素荧光的分析证实了相关的代谢变化。该研究表明，根系发育的增强与植物地上部分大量和微量营养素积累的增加密切相关，直接有助于生长改善和潜在产量提高。这些发现突出表明，通过对生根环境进行有针对性的代谢稳定来实现有效生根，对于大果蔓越莓的成功无性繁殖至关重要。
