Abstract:
A study was carried out in the southern zone of Moldova Republic to evaluate the influence of gibberelic acid (GA3) on the productivity of vines and quality of berries. It was established that the treatment of inflorescence of the seeded grape variety Codreanca by biological active substances - gibberelic acid (GA3) leads to increase in the size and weight of clusters and berries, productivity of vines and grape quality. We have established that for seeded grape variety Codreanca the maximal effect on the quality berries is application of GA3 in the first growth period (diameter berry – 5- 6 mm) with concentration 60 mg/l.
