“…In the previous studies, effects of Mycorrhizaroots and Vetozen on the growth and ECM colonization of spruce seedlings (Repáč et al 2014) and cuttings (Repáč et al 2011) were insignificant, similarly like in this study. Likewise, in small nursery inoculation trials no significant effect of Ectovit on spruce development was recorded in most treatments (Repáč et al 2011(Repáč et al , 2014Repáč, Sendecký 2018). The fertilizer as a component of the growth substrate composition and/or the application of fungicides and fertilizers during the growing period likely had a negative effect on the applied ECM fungi (Smaill, Walbert 2013).…”

“…Vuorinen et al (2015) developed a silica-based propagation medium for the large-scale production of ECM inoculum by solid state fermentation and proved ECM colonization of spruce root systems using this inoculum. https://doi.org/10.17221/29/2022-JFS In Slovakia, commercial mycelial-spore inoculum Ectovit and spore inoculum Mycorrhizaroots were applied into growth substrates in the nurseries to assess their effect on spruce development in juvenile stage (Repáč et al 2011(Repáč et al , 2014Repáč, Sendecký 2018). The results confirmed a negative impact of fertilizer and pesticide application on the efficacy of the inocula.…”

“…The fertilizer as a component of the growth substrate composition and/or the application of fungicides and fertilizers during the growing period likely had a negative effect on the applied ECM fungi (Smaill, Walbert 2013). Nevertheless, inoculation with Ectovit stimulated seedling growth and increased needle P and K concentrations in nutrient-not-enriched peat substrate contrary to nutrient-enriched one despite subsequent fertilization during seedling production (Repáč et al 2014). A positive influence of Ectovit on the needle nutrient concentration of spruce cuttings was also described by Repáč et al (2011).…”

“…Seedling roots are mostly naturally colonized with ECM fungi throughout seedling production in a nursery (Rudawska, Leski 2009). Development of seedlings and ectomycorrhizas is considerably affected by physical, chemical and biological properties of growth substrate and cultivation conditions (Brunner, Brodbeck 2001;Repáč et al 2014;Seyfried et al 2021). Particularly, usually high water content and fertility of growth substrate increase the seedling aboveground biomass while fine root biomass, root-to-shoot ratio and ectomycorrhiza formation decrease at the same time (Grossnickle, MacDonald 2017;Salcido-Ruiz et al 2020).…”

Seedling quality is an important input affecting the outplanted seedling performance. Morphological attributes and association with symbiotic ectomycorrhizal (ECM) fungi belong to influential traits determining seedling quality. In this study, the effect of pre-sowing applied commercial additives Ectovit (containing hydrogel and ECM fungi), Mycorrhizaroots (ECM fungi and nutrients) and Vetozen (natural mineral fertilizer) on the growth and ectomycorrhiza formation of Norway spruce seedlings grown in nutrient-poor pure peat in an open nursery site was assessed. Two-year-old bareroot seedlings were transplanted into containers. No significant growth differences were detected between treatments for 1 + 0 seedlings but the values of growth parameters (root collar diameter; stem height; shoot, root and total dry weight) of Ectovit-inoculated seedlings were significantly higher than those in the other treatments including the control after the second (2 + 0 seedlings) and the third growing season (2 + 1). Root-to-shoot dry weight ratio and number of root tips were distinctly higher after the third year compared to the previous two years but they were not significantly different between treatments. Mycorrhizaroots and Vetozen did not have any significant effect on seedling development. Although the occurrence of treatment-specific ECM morphotype was detected in Ectovit-inoculated seedlings, the high total ECM colonization of roots in all treatments including the control indicated a crucial impact of naturally occurring fungi on ectomycorrhiza formation.

An inoculation technique to create ectomycorrhizal symbiosis in 1.5-year-old Norway spruce (Picea abies (L.) Karst.) container seedlings was tested. The mycelia of ectomycorrhizal fungi (EMF) – Tylospora asterophora, Piloderma olivaceum, and Cenococcum geophilum – each grown in a silica dioxide powder carrier, was mixed with a conventional low-humified Sphagnum peat at the time of sowing. Seedlings were grown in four growth media: (1) conventional peat; (2) conventional peat mixed with sterile carrier; (3) conventional peat mixed with carrier containing T. asterophora and C. geophilum, (4) conventional peat mixed with carrier containing P. olivaceum and C. geophilum. The seedling development and EMF colonization was followed during the nursery production. Further, seedlings grown in the four media were planted on a former nursery field, and their development was observed for three years. At the end of the nursery production phase, there were no differences in the seedling height or stem diameter between the growing media. The colonization degree by the introduced EMF was low. The height growth of the seedlings inoculated with T. asterophora + C. geophilum was 16% higher during the first growing season after out-planting compared to seedlings grown in the conventional peat medium, but the effect was transient. At the end of the out-planting experiment, the seedlings grown in conventional peat had the highest proportion of healthy and lowest proportion of dead seedlings. The results emphasize the importance of the growing media for seedling quality and out-planting success. The tested inoculation technique was ineffective in creating substantial levels of EMF colonization.
