Влияние регулятора роста Pilarhance SL на урожайность и качество плодов вишни

Abstract

The investigations were carried out with Erdi Botermo sour cherry trees grafted on the mahaleb rootstock. The planting distance was 4.0 x 2.0 m, and the crown shape was mixed pyramid with reduced volume. The aim of the research was to study the effectiveness of Pilarhance, SL product as a growth regulator in different treatment doses to stimulate the growth and development processes of fruit in the sour cherry orchard. To achieve the planned objective, the following variants were studied: 1. Control, without treatment; 2. Pilarhance, SL, 0.8 l/ha; 3. Pilarhance, SL, 1.3 l/ha. On the basis of the obtained results, it was established that the growth regulator Pilarhance, SL can be included in the technological scheme for sour cherry cultivation at a dose of 1.3 l/ha, applied twice by foliar spraying. The first treatment should be carried out after flowering, and the next during the period when the color of the sour cherry fruits changes from green to yellow.
