Branovyts'ka T. The effect of gibberllin on the growth development and some biochemical indices of grapes sorts, such as Bastardo of Magarach, Kaberne Sovinion, Saperavi

Research subjects: technical sorts of grapes Bastardo of Magarach, Kaberne Sovinion, Saperavi. Research objectives: investigation of the influence gibberellin on the growth, crop production and seed sorts of grapes. Methods: conventional methods of investigation of viticulture were used. Theoretical and practical results: the method of using technical sorts of grapes is improved, optimal concentration is established. Recomendations for using gibberellin on the technical sorts of grapes are given. Novelty of introduced: the method of increasing of crop and quality of the grape sorts found on using gibberellin is carried out, it is proved that under the influence of free aminoacids is changed in the grape leaves, it is established that gibberellin spray contributes to accumulation of color substances and the general presence of phenol compouns, the presence of sugars is increasing, the acid of berries is dicreasing. Implementation degree: the reseach results are approved in cooperative plant "Alushta" of RPJSC"Masandra", 1996 - 2000. Effectiveness: inenecation effect per 1 he of vine-yard 502,9 gr., 546,0 gr., 457,1 gr. according to the sort. Sphere, sector of implementation: agriculture.
