In this year the buds have resisted over thewinter, so that the percentage of viability ofvegetation was 100, all varieties.Plant vigour, expressed through the length ofvegetative increases and the number of shootswith a diameter greater than 6 mm above theinsertion point, the values differ from onevariety to another (Table 3).Table 3.

The variety with vigour of the lowestwas Silvania (153 cm/3 shoots).In the III year (2012) have obtained the grapeson the buds located at base of vines because thebuds situated above the snow layer (about 30cm thick) were all perished.Because to the reduce temperature value thedry cutting was effectuated using the shortelements, of 2-3 eyes length. Even in theseconditions have not been in all growth buds, atall varieties. The percentage of bud growth wasbetween 70 and 100 (Table 4). Two varietieshave a viability percentage of 100%, Timpuriude Cluj i Splendid, only. The lowest number of225buds go in the vegetation at the Taminavariety, 68 percent. With the growth of budsover 90% were most varieties, 8, Silvania andMuscat of Hamburg, with a percentage of 95.Other varieties have a percentage of the growthof buds between 80 and 89.Vines vigour was expressed by the sum of totalannual increases, the number of eyes formed onthe vine and the number of shoots with adiameter greater than 6 mm, in the course of ayear.The difference of vigour between the vines arevery large, in specially, as regards the amountof the total annual increases and the number ofeyes formed on the vine in the course of a year(Table 4).Thus, if the Silvania variety recorded 625cm/vine, the annual increases and 64 eyesformed on the vine, at the Victoria variety, thesame elements have values of 1364 cm/vineand 84 eyes/vine. The less vigorous varietiesare part of Silvania, are Timpuriu de Cluj andSomean. Differences were recorded regardingof the number of the shoots with diameter of 6mm to the vine, which has values from 3 to 5.Although it suffered considerable losses ofbuds and wood stocks were able to fruiting,even if not at the level of genetic potential. Haddemonstrated the potential of fruiting of thesevarieties to make grapes on the short elements(2-3 eyes length). If some varieties of fruitingprocess was symbolic, others that productionwas at the level of a normal year fromclimatical point of view, with a large capacityof fruiting on the short elements inserted to thevine base, such as the Transilvania (10073Kg/ha) and the Prima Cl. 1022 (9998 Kg/ha),(Table 5). A level of production have beensatisfied with the varieties Muscat de Hamburg(5302 Kg/ha), Muscat de Hamburg Cl 202(4999 Kg/ha) and Victoria (4923 Kg/ha).Without the potential for fruiting on the shortelements were Otilia (1515 Kg/ha) Somean(2196 Kg/ha), Napoca (2272 Kg/ha) andCoarn neagr selecionat (2575 Kg/ha). Thequality of production of grapes had advantagesand disadvantages due to the climaticalconditions of this year for agriculture (Table 5).
