Eurasian and interspecific grape varieties and candidates were inspected for biological productivity in the variety collection of the University of Debrecen at the Horticultural Experimental Station in Pallag. In this paper, data are reported on yields (kg/stock), cane production (kg/ stock) and use-up index of wood yield of each cultivar in the experimental years 2011-2012. From the range of Eurasian (Vitis vinifera L.) white wine-grape qualified cultivars and candidates ’Ezerfürtû’, ’Generosa’, ’Jubileum 75’, ’Müller Thurgau’, ’Zöld veltelíni’,’B-11’, ’CSFT-92’, ’Pintes’, from the range of Eurasian (Vitis vinifera L.) red wine-grape qualified cultivars and candidates ’Kármin’, ’Pinot noir’, ’Alicante Bouschet’ and ’Rubintos’ were highlighted. Promising data of interspecific ’Aletta’, ’Csillám’, ’Kunleány’, ’Orpheus’, ’Refrén’, ’Taurus’, ’Viktória gyöngye’, ’Alföld 100’, ’Reform’, ’RF38/32’, ’Toldi’ white, and ’Dunagyöngye’ ’Pannon frankos’ red wine-grape cultivars and candidates were emphasized. Published data refer only to the biological performance of the cultivars. The thorough evaluation of varieties needs respect to data on resistance to fungal disease and climatic extremities, and other characteristics concerning production technology and oenological parameters.

Climatic accidents increase in frequency due to climatic changes. Hailstorms are typically localized events and are known few studies about their effect on grapevine. The objective of this study was to examine the vine vegetative balance responses to natural hail, registered when shoots were 10-15 cm height. Four grape cultivars (Vitis vinifera L.), two for red wine (Feteascǎ Neagrǎ, Pinot Noir) and two for white wine (Chardonnay, Tǎmȃioasǎ romȃneascǎ) were studied in Dealu Mare, one of the most known vineyards in Romania. Visibly, the extent of the hailstorm damage was great, enough to injure or remove about 90% of shoots growth till hail fall. Three treatments with Delfan Plus (amino-acids complex) were applied on grapevine canopy. Number of shoots/vine and number of fertile shoots/vine were counted and biologic balance of grapevine indexes were calculated. Our results indicated that natural hail affect significantly the number of fertile shoots. Delfan Plus treatments positively influenced the number of shoots and fertile shoots. Delfan Plus treatments had little influence on Recovery index, vine Balance indexes and Ensurance Coefficient after one single year of study. The capacity of recovery after hail fall, in this case, is more influenced by the grape cultivar. The present work is the first attempt to enhance our understanding on the vegetative responses of grapevines to the use of biostimulants and to natural hail, which is an extreme and complex natural phenomenon.

Grape Varieties

The cultivation of grapes for the production of wine at altitudes between 2,200 and 2,600 masl started in the department of Boyacá in 1982. Quality wines are produced by the Ain Karim Vineyard in Ricaurte High. It is necessary to have wine grapes that possess suitable organoleptic compounds at harvest in order to guarantee quality grape must that can be converted into wine. For this, it is necessary to have a suitable ratio between the inflows and the outflows and to guarantee production, quality and vegetative sustainability over time, conserving the equilibrium and benefiting the productive potential of the vineyard. This study aimed to evaluate the productive and vegetative balance effect in the wine grape varieties (Vitis vinífera L.) Cabernet Sauvignon and Sauvignon Blanc in Sutamarchán-Boyacá, considering different pruning types (short, long, and mixed). A bifactorial, completely random statistical design was used. At the time of harvest, the fruit production and pruned wood were evaluated. The long-pruned vines presented the best behavior and the most balanced inflow/outflow ratio, while Sauvignon Blanc demonstrated a better productive yield. Meanwhile, the short and mixed prunings presented the better values for the ravaz index, indicating that they are more suitable for the conditions of the region, allowing for sustainability during the productive cycles of the wine grapes.

Propagation Material

For several thousand years, vine has been grown in the Carpathian basin, where the climatic and soil conditions are favourable for viticulture. During this long period, vine growing has been developing until it reached its current niveau. We grow propagation material, table grape and wine grape. The produced wine grape varieties are grown on the largest area, of which 72% is white wine and 25% is red wine. Only 3% remains for table grapes. The surface of vineyards is about 63 000 ha, which can be found in 22 wine regions. The biodiversity of vine is very rich in our country. There are a lot of native and valuable bred varieties and clones in cultivation. The resistant and winter frost resistant vine varieties have an important role in our continental climate. The in 75% of the vineyards is on hills and mountains, 25% of them is on the Great Hungarian Plain. High cordon with cane pruning dominates the training and pruning system. Unfortunately, vine stocks suffer from a lot of diseases and by using pesticides we pollute the nature. Viticulturists in Hungary produce excellent raw material and provide oenologists with them who make wine of excellent quality.
