Abstract
U radu su predstavljeni rezultati trogodišnjeg ispitivanja self-(in)kompatibilnosti kod četiri ekonomski značajna genotipa trešnje -'Karina', 'Kordia', 'Regina' i 'Summit', u agroekološkim uslovima Srbije. Određena je alelna konstitucija S-RNaze, utvrđen stepen rasta polenovih cevčica metodom fluorescentne mikroskopije, kao i stepen zametanja plodova pri samooprašivanju navedenih genotipova. 'Kordia' (S3S6), 'Regina' (S1S3) i 'Summit' (S1S2) su self-inkompatibilne, sa značajnim brojem polenovih cevčica koje završavaju rast u srednjoj trećini stubića, uz odsustvo zametanja plodova. 'Karina' (S3S4 genotip) je ispoljila selfkompatibilnost, imajući u vidu da su polenove cevčice pri samooprašivanju dostizale bazu stubića i plodnik, prodirući u nucelus semenog zametka. Pored toga, zametanje plodova kod sorte 'Karina' utvrđeno je u svim godinama ispitivanja (40,26%, 18,79% i 21,81%, resp.).
The paper presents results of a three-year study of self-(in)compatibility in four economically important sweet cherry genotypes - 'Karina', 'Kordia', 'Regina' and 'Summit', under agro-environmental conditions of Western Serbia. Determination of S-RNase genotype, microscopic observation of the pollen tube growth rate and assaying of the fruit set level after self-pollination were used to assess the genotypes. 'Kordia' (S3S6), 'Regina' (S1S3) and 'Summit' (S1S2) are self-incompatible genotypes, with a considerable number of pollen tubes ending the growth in the middle third of the style and lack of fruit set. 'Karina', as S3S4 genotype, behaved as self-compatible, since its pollen tubes reached the base of the style and ovary, penetrating the nucellus. In addition, fruit set for 'Karina' was recorded in all three years of study (40.26%, 18.79% and 21.81%, respectively).
