Abstract
In vitro pollen germination was determined in five peach cultivars, Prunus prsica (L.) Batsch cv. Dixired, Redheaven, Gloheaven, Suncrest and Summerset, Different sucrose concentrations (10%, 15%, 20%), sowing times (fresh pollen, 7 days old pollen, and 14 days old pollen), temperatures (10 degrees C, 15 degrees C, 20 degrees C, 25 degrees C) and incubation times (3h, 6h, 12h, 24h) were tested. It was found that, in addition to the significant influence of genotype, pollen germination depended on sucrose concentration, sowing time and temperature, while incubation time had no influence. The majority of tested peach cultivars had the highest pollen germination in 10% sucrose concentration, with fresh pollen, under 15 degrees C, and 12h after incubation.
