Влияние регуляторов роста на стимулирование плодообразования, продуктивности и качество плодов яблок сорта Голден Делишес

Abstract

The experimental plot is placed in the orchard “Accesal” Ltd. founded in 2009. The study subject of the experience was Golden Delicious apple variety grafted on M 26. The trees were trained as slender spindles. The distance of plantation is 4.0 x 2.0 m. The tested gibberellic acid was GA4+7, product Gerlagib LG and Gibbera, EW. To study the influence of the treatment on fructification and quality of Golden Delicious apple variety, four variants were experimented: 1. Control – no treatment; 2. Gerlagib LG – 0,5 l/hа; Gibbera, EW – 0,25 l/hа; Gibbera, EW – 0,50 l/hа. In the present research work, we demonstrated that Gerlagib LG, or Gibbera, EW product may be included in the technologic system to stimulate fruit formation, productivity and quality of fruits to administered in the dose 0,5 l/ha, up to 3 times, starting from petal fall stage and continuing intervals of 7-10 days.
