Homogeneity of plant development depends on the qualityof planting material and agrotechnics used. In our study on vineyards, the vines were classified in three groups - thesmall, medium and large vines. The vines within each group were studied weak, medium and strong shoots, setting aspecific correlation.Key words: biometric indices, Cardinal variety, influence.INTRODUCTIONViticulture is and will remain one of the basicbranches of economy of the Republic ofMoldova. Today the scientists are working toselect the varieties and clones resistant tovarious adverse factors, high productivity andquality. Moldova has favorable conditions forgrowing grapes, but winters in recent yearshave lower minimum temperatures influencingproductivity and quality. Therefore,recommended to protect the vines of tablegrapes' varieties and clones with soil even inthe South of Moldova, especially varieties withearly bud break, for example, the table grapevariety Cardinal.The grapes' resistance to frost and winterconditions is a multilateral particularities of thevines, because gradually formed long beforeinstalling the low temperatures. This complexof characteristics and agronomic measures aredetermining the longevity of vineyardplantation and the development level of vines.The vines of the Cardinal variety arecharacterized with average growth vigor. Levelvine growth is determined mostly by thehomogeneity and quality planting material.The vigor of varieties is given with in a lengthand diameter of the shoots. In the experience,we studied both data diameter as well as length.MATERIALS AND METHODSThe vineyards which we studied are located inCopceac village, Stefan Voda district, in aSouth-East part of Republic of Moldova, in2011-2012 years.The vines of vineyards were classified intothree categories: small grow vigor, mediumgrow vigor and large grow vigor and the shootswere classified into the same three categories.The observations and analyzes were performedaccording to current guidelines (Mnescu,Creola, .a., 1989; Perstniov, N, .a., 2000).Results were processed by the method ofcorrelation and regression analysis:- small grow vigor vines (y 1 , y 2 , y 3 , y 4 ),medium grow vigor vines (y 9 , y 10 , y 11 , y 12 ),large grow vigor vines (y 17 , y 18 , y 19 , y 20 ),general data (y 25 , y 26 , y 27 , y 28 );- small grow vigor shoots (y 1 , y 9 , y 17 , y 25 ),medium grow vigor shoots (y 2 , y 10 , y 18 , y 26 ),large grow vigor shoots (y 3 , y 11 , y 19 , y 27 ),general data (y 4 , y 12 , y 19 , y 28 ).RESULTS AND DISCUSSIONSCardinal-is an early table grape variety. Thegrapes are large, cylindrical-conical shape. Theberry density is different. The berries are verylarge, spherical or oval, red-violet, coveredwith obscure bloom. The peel is thick, butedible. The berries begin to ripening in late I-IIdecade of august. Productivity is high. Thegrapes have a high transportability.61
