- Abstract
Chemical thinning consists in spraying the trees with different substances. The intensity of chemical thinning depends on the vigour of the tree, the phenophase in which it is done, the type of solution and its concentration. In this study for the chemical thinning the following products were used: Ethrel, 0.01% in concentration, Cosavet 80 DF, in concentration of 5%, Sulphur 80 WG, in concentration of 5% and Sulfomat 80 PU, in concentration of 5%, when 80% of the flowers were open. The study took place in fruit-growing ecosystems Calacea and Steluţa, by analyzing 7 varieties of plum, in the following order: 'Tuleu timpuriu', 'Stanley', 'Gras Ameliorat', 'Anna Spath', 'Tuleu gras', 'Vinete Româneşti', 'Vinete de Italia' and 'Nectarina roşie'. On these varieties were conducted determinations regarding thinning in..luence on: dry substance and total acidity. In Calacea fruitgrowing ecosystem, regardless the treatment, the highest dry substance content was obtained by 'Stanley' variety (15.57 %), and in Agroindustriala ecosystem, the highest value for dry substance content was registered by „Vinete de Italia' variety (20.19 %). The results show that regardless the treatment, in Calacea fruit-growing ecosystem the highest value for acidity was obtained by „Tuleu Timpuriu' variety (10.9540 %), and in Agroindustriala fruitgrowing ecosystem the highest acidity was registered by „Tuleu Gras' variety (12.88 %).
