Comportarea unor soiuri de cais conduse după coroana trident în zona de nord a ţării

Abstract

The researches were conducted during 2020 in the orchard of “Vilora” enterprise (northern zone of Moldova). The object of the research was apricot trees of Spring Blush, Pinkcot, Kioto and Faralia varieties, grafted on the Myrobalan 29C rootstock. Planting distance was 4.0x2.2 m. The planting of apricot trees was carried out in spring of 2018. Trees were trained to a Trident canopy. It was established that the biological characteristics of the va-riety influenced the parameters of trees, vegetative macrostructure and fruiting microstructure, the onset of phenopha-ses of generative organs, the period between flowering and harvest maturity of these apricot varieties, morphological parameters of fruits and stones, shape index, orchard productivity and fruit distribution in diverse quality classes. The Kioto variety had a higher resistance to spring lower temperatures which are frequently occurring in our country. In the conditions of the northern area, it recorded yields of 17.03 t/ha in the third year after planting.
