Pollen germination in apricot cultivars (Prunus armeniaca L.)

Abstract

In 23 apricot cultivars pollen germination in vitro using the method of germination on the medium with agar and sucrose solution of three different concentrations (10, 15 and 20%) were studied. Studies were done during two-year period (2005-2006). Pollen germination of studied cultivars ranged from 21.2 to 79.5%. Differences between cultivars, sucrose concentrations and years were statistically very significant. In majority of cultivars the best germination was achieved in sucrose concentration of 10%. .

Kod 23 sorte kajsije proučavana je klijavost polena "in vitro", metodom naklijavanja na hranljivoj podlozi sa agarom uz dodatak rastvora saharoze tri različite koncentracije (10, 15 i 20%). Ispitivanja su obavljena u periodu od dve godine (2005-2006). Klijavost polena ispitivanih sorti varirala je u intervalu od 21,2-79,5%. Razlike između sorti, koncentracija saharoze i godina ispitivanja bile su statistički veoma značajne. Kod većine sorti najbolja klijavost je dobijena u rastvoru saharoze koncentracije 10%. .
