Abstract

Mycorrhizal symbiosis has an important role for the grape: it helps the water - and nutrient uptake, as well as the avoidance of biotic and abiotic stresses. During our investigation carried out on stocks grown in Szigetcsép (Kunság wine region), we studied the effects of different bud load on the degree of mycorrhizal colonisation. The vineyard (Gál Vineyard and Winery in Szigetcsép) is on sandy soil with low nutrient content, thus the mycorrhizal colonisation have a great importance in this area. For the estimation of endomycorrhizal colonisation, fine roots of the grape cultivar ’Kékfrankos’ were stained with anilin-blue, and investigated under light microscope. Our results show significant difference of the mycorrhizal colonisation in our experiments, however, further studies are needed in other wine regions for general conclusions to be drawn.
