Vreme cvetanja i grupe inkompatibilnosti - sortna kompozicija u komercijalnim zasadima trešnje (Prunus avium L.)

Abstract

U radu su prikazani osmogodišnji rezultati (1999-2006. godine) ispitivanja karakteristika fenofaze cvetanja 21 introdukovane sorte trešnje u agroekološkim uslovima Čačka. Ispitivani su tok, trajanje i obilnost cvetanja, i izvršena klasifikacija ispitivanih sorti prema vremenu cvetanja. Na bazi prosečnog višegodišnjeg preklapanja u fenofazi punog cvetanja, kao i na osnovu do sada poznatih podataka o pripadnosti ovih sorti pojedinim grupama inkompatibilnosti, iznete su mogućnosti za njihovo gajenje u višesortnim zasadima koje mogu obezbediti efikasno oprašivanje i oplođenje, a time i realizaciju potencijala rodnosti.

The paper presents results of eight-year study (1999-2006) of flowering phenophase in 21 introduced sweet cherry cultivars grown under the agro-environmental conditions of West Serbia. Flowering time, as well as progress and abundance of flowering were studied, and classification of the studied cultivars according to flowering time was derived. On the basis of mean several-year overlap in phenophase of full flowering and on the grounds of so far known data on classification of these cultivars among incompatibility groups, we have offered a recommendation for their cultivation in orchards whereby the most effective pollination and fertilization can be ensured as well as good fruit-set and satisfactory fruit yields.
