Seasonal root development of Cabernet sauvignon grafted on different rootstocks
Published September 7, 2014
61-63.

The minirhizotron system gives opportunity to study the root development without disturbing the soil and root. We have found certified differences in root development during the year 2013 among the rootstocks grafted on ‘Cabernet sauvignon’. The number of roots varied according to the rootstocks in different depth of soil layers and also va...ried the development of ripeness of the root system. We conclude that root system development is affected by soil physical and chemical properties, but differences according to the rootstock genotype on the similar type of soil exist.

The examination of the broadleaf evergreen ornamental shrub species in Keszthely
Published September 6, 2010
27-30.

The examination of production possibilities of woody ornamental shrubs (originating from warmer regions than our country) commenced with the financial support of the INTERREG IIIA Slovenia – Hungary – Croatia programme at the Department of Horticulture of the University of Pannonia’s Georgikon Faculty in spring 2007. Our examinations focu...sed on the appearance of species in our country as well as on their frost resistance abilities. The species participating in the experiment are as follows: Abelia grandiflora, Aucuba japonica ’Rozzanie’, Calycanthus floridus, Cotoneaster franchettii, Elaeagnus pungens ’MaculataAurea’, Ilex cornuta, Ligustrum sinense, Ligustrum texanum, Nandina domestica, Osmanthus heterophyllus, Perovskia atriplicifolia, Phyllyrea angustifolia, Photinia fraseri ’Red Robin’, Prunus lusitanica, Sarcococca hoockeriana, Spartium junceum, Teucrium fruticans, Viburnum cinnamonifolium, Viburnum tinus.

The development and reproduction of grape phylloxera (Daktulosphaira vitifoliae Fitch) strains of Hungarian vine-districts in root-bioassays
Published November 15, 2004
67-71.

The root bioassay method allows for 4-6 week continuous observation of grape phylloxera feeding on the grape root. 10 Hungarian phylloxera strains were compared on susceptible Vitis vinifera cv. Chardonnay and the resistant rootstocks of V. berlandieri x V. riparia Teleki 5C and V. berlandieri x V. rupestris ...Georgikon 121 in in vitro observations. The strains originated from Villany and Eger (Figure 3) had higher reproduction on the root of V. berlandieri x V. riparia Teleki 5C (201 and 119 eggs) and were more aggressive than the others (average production 10 eggs). The continuous high level of survival, development and reproduction of the Eger strain on Teleki 5C (V. berlandieri x V. ripuria) until day 46 may be due to adaptation.

Study on the viruses of Petunia in Hungary
Published October 16, 2002
55-59.

Virus susceptibility of 11 varieties of vegetatively propagated petunia against 2 virus strains (TMV-C/U1 and PVYNTN) were examined. Neither resistant nor tolerant varieties of petunia were found. The virus infection of the Petunia genus was examined in Hungary. The most common pathogens were the Tobacco mosaic tobamovirus (TM...V) and the Tomato mosaic tobamovirus (ToMV), but the samples also contained Alfalfa mosaic alfamovirus (AMV), Cucumber mosaic ClIC11171014171S (CMV) and Potato Y potyvirus (PVY). Potato X potexvirus (PVX) was isolated in the varieties of trailing petunia for the first time.
