Cilj istraživanja bio je utvrditi učinak živoga mikoriznog cjepiva na dinamiku opskrbljenosti biljnim hranivima vinove loze. Pokus je proveden na kultivaru Graševina (Vitis vinifera L.), cijepljenome na podlozi SO4 u uvjetima Vinogorja Kutjevo. Uzgojni oblik je Guyot, s opterećenjem od 10 pupova. U neposrednu blizinu korijenova sustava inokulirano je 20 ml mikorizne suspenzije koja sadrži oko 2000 propagacijskih jedinica živoga mikoriznog micelija. Istraživanje je provedeno u dvama klimatski vrlo različitim godinama. Prvu godinu istraživanja (2014.) karakterizirale su obilne oborine i manje sunčanih dana, što je rezultiralo kasnijom tehnološkom zrelošću grožđa od 34 dana u odnosu na 2015. godinu, koja je u periodu dozrijevanja grožđa bila iznadprosječno topla i suha. U obje godine istraživanja, u uvjetima slabe opskrbljenosti tla organskom tvari, fosforom i kalijem, mikorizna simbioza utjecala je na veći sadržaj fosfora i kalija u suhoj tvari list kultivara Graševine. U godini s više oborina i manje topline utvrđen je veći sadržaj dušika u listovima trsova s mikoriznom simbiozom. U suhim i toplim uvjetima tijekom cijeloga perioda dozrijevanja grožđa povećan je sadržaj kalcija, a opravdano veći sadržaj cinka, mangana i željeza utvrđen je u periodu neposredno prije tehnološke zrelosti grožđa. Nije utvrđen pozitivan utjecaj mikorize na urod, sadržaj šećera i ukupnu kiselost.; The aim of the study was to determine the effect of a live mycorrhizal vaccine on the dynamics of grapevine’s plant nutrient supply. The experiment was performed on the Graševina variety (Vitis vinifera L.), grafted on an SO4 rootstock in the conditions of the Kutjevo Vineyards. The training system was Guyot, with a 10‐bud load. In the root system’s immediate vicinity, 20 ml of mycorrhizal suspension containing approximately 2,000 propagation units of a live mycorrhizal mycelium were inoculated. From the viticultural aspect, the research was conducted in two climatically very different years. The first research year (2014) was characterized by an abundant precipitation and less sunny days, resulting in a later technological grape maturity, amounting to 34 days when compared to the year 2015, which was extraordinarily warm and arid during the grape ripening period. In both research years, in the conditions of the soil’s low supply with the organic matter, phosphorus, and potassium, a mycorrhizal symbiosis influenced the higher content of phosphorus and potassium in the Graševina’s dry leaf matter. In a year experiencing more precipitation and less heat, a higher nitrogen content was found in the vine leaves manifesting a mycorrhizal symbiosis. In the dry and warm conditions, the calcium content was increased during the entire period of grape ripening, and a justifiably higher content of zinc, manganese, and iron was found in the period immediately preceding a technological grape ripeness. A positive influence of mycorrhiza on the yield, sugar content, and total acidity was not determined.
