Intensitatea luminii în coroana pomilor de cireș formați după coroana fus zvelt

Abstract

The research was carried out on the Kordia cherry variety, grafted on Gisela 6, planted at a distance of 4x1 m. The 7-year-old trees are led by the slender spindle crown with the rows located from north to south. The light intensity in the crown of the trees was measured at the end of July, in clear weather from 7 a.m. to 5 p.m., every 2 hours, with the universal pyranometer M-80 and the galvanometer GSA-1. Based on the obtained data, the light intensity was calculated in the center of the crown, along the axis and in the area where the crown joins, both in the East and West of the row of trees, as well as in the shadow of the crown.
