- Abstract
Fruit peel color is an important quality parameter and marketing attribute that influences consumer acceptance. Red color development in apples is due to the formation of anthocyanin pigments in the apple skin. Anthocyanin production, and therefore apple color is influenced by a range of environmental and management factors in the orchard. Ethephon is a compound that slowly releases ethylene which in turn can stimulate anthocyanin accumulation in apples. The aims was to evaluate the influence of ethephon to the color development of 'Gala Must' apple variety. The study subject of the experience was Gala Must apple variety grafted on M 9. The trees were trained as slender spindles. The distance of plantation is 3.5 x 1.2 m. To study color development of the apple fruits were experimented the following variants of treatment: 1.Control -- no treatment; 2. Ethephon -- 300 ppm; 3. Ethephon -- 400 ppm. Ethephon were sprayed one time 2 -- 3 weeks before commercial harvest. The research was conducted during the period of 2013 year. During the research, it was studied the amount and average of fruits, tree production, quality, firmness of fruits, hydrolysis and color index. In the present research work, it was demonstrated that ethephon may be included in the system of color development of "Gala Must" apple variety fruits, the dose of 400 ppm, applied one spray 2 - 3 weeks before commercial harvest, where the level of profitability was 184.0%.
