Tétel Szabadon hozzáférhető Comparative study of sour cherry samples for their anthocyanin content measured by tools of the laboratory and by portable equipments(2010) Szemán-Nagy, Gábor; Pintér, Gábor; Prokisch, József; Tornyai, Julianna; Nyéki, József; Szabó, Zoltán; Szabó, T.; Fári, MiklósTétel Szabadon hozzáférhető Comparison of varying pollen source on productivity of sour cherry (Prunus cerasus L.) cultivars(2010) Davarynejad, Gholamhossein H.; Nyéki, József; Szabó, Tibor; Tornyai, Julianna; Szabó, Zoltán; Soltész, Miklós; Davarynejad, E.Tétel Szabadon hozzáférhető The effect of location on the incidence of brown rot blossom and shoot blight infection on apricot(2005-09-14) Drén, Gábor; Szabó, Zoltán; Nagy, János; Dani, Mária; Thurzó, Sándor; Racskó, József; Tornyai, Julianna; Erdős, Zoltán; Molnár, Barnabásné; Nyéki, József; Holb, ImreThe aim of our study was to assess the incidence of brown rot blossom and shoot blight and caused by Monilinia laxa. Assessments of incidence were made on cv. Bergeron (susceptible to brown rot) in a flatland and a hilly growing area (at Cegléd and Gönc, respectively). In 2004, when spring and summer weather conditions were wet and cold, incidence reached 95 % for blossom blight and 33 % for shoot blight in the untreated plots. Blossom blight incidence was 1.5-2 times higher in the flatland area compared to the hilly growing area. During the blooming period of apricot, two (at flower bud stage and at full bloom) and three (at flower bud stage, at full bloom and at petal fall) fungicide applications were necessary for the successful control at Gönc and Cegléd, respectively. The difference between the two orchards was due to the fact that blooming started one week later in the hilly region (at Gönc) than in the flatland region (at Cegléd), therefore, the critical weather period coincided with blooming in the orchard in the hilly region only partially.Tétel Szabadon hozzáférhető Effects of self and cross pollination on fruit set and fruit quality of sour cherry cultivars(2010) Ansari, M.; Davarynejad, Gholamhossein H.; Tornyai, Julianna; Nyéki, József; Szabó, Zoltán; Soltész, MiklósTétel Szabadon hozzáférhető Environmentally-benign plant protection possibilities against domestic Monilinia spp. in organic apple and stone fruit orchards(2005-09-14) Holb, Imre; Szabó, Zoltán; Drén, Gábor; Thurzó, Sándor; Racskó, József; Dani, Mária; Tornyai, Julianna; Nyéki, JózsefIn this study, possibilities of environmental-friendly plant protection against domestical brwon rot species were summarized for oecological pome and stone fruit orchards. Symtomps of the two most important brown rot species (Monilinia fructigena (Aderh. & Ruhl.) Honey and Monilinia laxa (Aderh. & Ruhl.) Honey) were described and then cultivar susceptibility to brown rot was discussed. Furthermore, mechanical, agrotecnical, biological, and other control possibilities (stone powders, plant extracts and restricted chemical materials) were shown.Tétel Szabadon hozzáférhető The Hungarian pear germplasm as source of genetic variability for breeding programmes(2010) Szabó, Tibor; Labuschagne, Iwan F.; Musacchi, Stefano; Nyéki, József; Tornyai, Julianna; Soltész, Miklós; Szabó, Zoltán
