    The effect of cluster thinning, cluster tipping, cluster shredding and defoliation at the flowering on the vegetative and generative vine performance from Kékfrankos Cv.
    (2012-04-25) Fazekas, I.; Göblyös, J.; Bisztray, Gy. D.; Zanathy, G.
    The cluster thinning is a method of the yield regulation.With the removal one part of the clusters, the yield pro leaf area will be lower, hereby the grape and wine quality will be improved. The regulation of the yield can lead to further advantages: the ratio of the vegetative and generative performance of the vines will improve, the condition of the plants will better, the number of the physiological diseases can be reduced and the growth of the shoots and roots can be promoted. The grape growers make the cluster thinning almost exclusive by creating one cluster shoots. Usually the upper clusters are removed, because the sugar content of these second or third clusters will be lower. The cluster thinning is an easy task, can be done without special skills. It is an effective method improving wine quality, but its use can lead to other problems. The grapes try to compensate the removed clusters. Therefore the clusters will be bigger and thicker, but more sensitive to bunch rot. Moreover the treatment is expensive, because it needs manual work. It is worth to get acquainted and try the new yield regulation methods, which can help to avoid the occurring problems. Our aim is to show the results of our experiment, which was carried out in Eger, examining the red grape cultivar Kékfrankos. During our 4 years long experiment we compared the effects of cluster thinning, cluster shredding, cluster tipping and defoliation at the flowering, on the vegetative and generative vine performance.

    The investigation of suitability to various purposes of industrial processing in stone fruit varieties and variety candidates
    (2006-06-20) Kerek, M. M.; Erdős, Z.; Fazekas, I.; Nyéki, J.; Szabó, Z.
    In the laboratory of Conserve-technology in the Research Institute for Fruit Growing, Company of Public Utility, Cegléd, 6 sour cherry, 6 apricot, 5 peach and nectarine, 6 plum and 4 Japanese plum varieties (canned fruit, juice, dried fruit, deep frozen). The products were evaluated by organoleptic methods on a scale of 1-5 steps. The varieties receiving at least 4 points were listed (in brackets also the respective product was indicated): `Kántorjánosi' sour cherry (for all the three purposes), '13' variety candidate (canned and deep frozen), 'T' var. cand., (canned, deep frozen), 'Érdi bőtermő' (dried fruit), 'R' var. cand. (deep frozen); ‘Ceglédi arany', 'Ceglédi bíborkajszi', 'Magyar kajszi"C. 235' (fibrous juice); `Babygold 5', 'Redhaven' peaches, and 'Caldesi 2000' nectarine (canned); 'Stanley' plum (canned), 'Besztercei Bt, 2' (deep frozen).

    Investigation of the cultivation value of old grapevine cultivars in Tokaj in 2004-2006
    (2007-05-15) Varga, Zs.; Bényei, F.; Bodor, P. Jr.; Fazekas, I.
    Most of the cultivars grown before the disaster of phylloxera in Tokaj can be found only in grapevine collections. The aim of our study was to determinate the cultivation values of six old grapevine cultivars of the wine-region, namely 'Balafánt', 'Budai gohér', 'Purcsin', 'Török gohér, 'Piros (red) furmint' and 'Változó (altering) furmint'. Based on the results of the investigations from 2004 to 2006 it can be concluded that among from the examined cultivars of Tokaj `Budai gohér', Turcsin' and 'Változó furmint' match the best with the technological and consumer requirements of recent days. However the yield of 'Budai gohér' in certain vintages is not acceptable and red wine cultivars are not permitted at this time in the wine-region, but in qualitative responses these presented steadily good data. On the other hand the lowest sugar content was measured and development of noble rot was not registered at all in case of Piros furmint' and `Balafánt'. Their spread in Tokaj is not probable.
