Influence of bioproducts and mycorrhizal fungi on the growth and yielding of sweet cherry trees

Abstract

The experiment assessed the influence of various biofertilizers and biostimulants on the growth characteristics of the root system, its colonization by arbuscular mycorrhizal fungi and the yielding of sweet cherry trees in field conditions. The experiment, conducted in Pomological Orchard of Research Institute of Horticulture located in Skierniewice during 2011–2014, involved the use of a mycorrhizal substrate, organic fertilizers and biostimulant in randomised block design. The control combination consisted of plants fertilized with mineral fertilizers (NPK). The use of the organic fertilizer BF Ekomix in dose 100 g per tree each year in the spring significantly increased the number of root tips in comparison with the control trees. There was also a tendency for the roots to lengthen and increase their surface area under the influence of this biofertilizer. In addition, the inoculation of roots with the mycorrhizal substrate in dose 200 g per tree per year stimulated the colonization of the roots of sweet cherry trees by arbuscular mycorrhizal fungi, which in turn led to improved root growth parameters.

Biostimulants to Improved Tree Physiology and Fruit Quality: A Review with Special Focus on Sweet Cherry

“…Other results indicate that the use of a mixture of AMF (Rhizophagus intraradices, Funneliformis mosseae, Claroideoglomus etunicatum, Rhizophagus clarus) increases root diameter, root volume, and root fresh and dry weight of one-year-old sweet cherry trees (cv. Vanda) grafted onto the "Gisela 5" rootstock [146]. Positive results were also observed for cherry rootstocks, "Edabriz" and "Gisela 5" inoculated with several Glomus species.…”

The effectiveness of the use of microbiological preparations when interacting with seed stocks of the genus Prunus L.

“…Promote the growth and development of plants, including through the production of phytohormones and the ability of microorganisms to increase the amount of nutrients and physiologically active compounds available to plants [13,14]. They carry out molecular interactions, exchange of metabolites and their transformation [15]. They increase the biological potential of plants, thanks to the mechanisms of symbiotic interaction; reduce the harmful effects of herbicides and chemical pollutants.…”

Microbial consortiums applied in seedling production system of avocado cultivar "Criollo"

“…(Viera et al, 2017a), mientras que en plántulas de chirimoyo se reportó mayor biomasa y contenido de fosforo (Viera et al, 2017b); en arándano (Vaccinium corymbosum) incrementó el peso seco de raíces y brotes (Schoebitz et al, 2016); en cerezos (Prunus sp.) aumentó el diámetro, volumen y peso seco de raíces (Gluszcek et al, 2020). Resultados similares se observaron con aplicaciones de consorcios bacterianos y fúngicos en plantas de frutilla (Todeschini et al, 2018).…”
