Influenţa produselor pe bază de 1-NAD şi 1-NAA asupra calităţii fructelor de cireş din soiul Regina în sistemul superintensiv de cultură

Abstract

The experimental plot was placed in the orchard “Farm Prod” Ltd. founded in 2015 year. The study subject of the experience was Regina cherry variety, grafted on Gisela 5. The trees were trained as slender spindle system. The distance of plantation is 4.0×1.5 m. The research was conducted during the period of 2019 year. To study the effect of Auxiger preparation on physiological processes, fruit production and quality the following variants of treatment were experi mented: 1. Control – without treatment; 2. Auxiger, 0.5 l/ha; 3. Auxiger, 0.7 l/ha; 4. Auxiger, 0.9 l/ha. The active ingredient of Auxiger is constituted by 1-naphthylacetamide (1-NAD – 1.5 g/l) and 1-naphthylacedic acid (1-NAA– 0.6 g/l). The growth regulator Auxiger were sprayed one time, during the period of intensive fruit growing, when the fruits diameter was 12–13 mm (26.05.19). During the analyzed period, it was established that the physiological processes intensified, average weight of fruits, the productivity, fruit size, period of maturation increased while the cracking index reduced, when treating with Auxiger growth regulator in dose of 0.7 l/ha.
