Abstract

Like all phenological processes, microsporogenesis is mainly determined genetically, but its phenotypical expression is greatly influenced by environmental factors, particularly the temperature. During the 3-year experimental period, the process of microsporogenesis was examined in eight apricot cultivars originated in North America and in Romania. The Hungarian cultivar ‘Gönci magyar kajszi’ was used as the control. Based on the results it was possible to rank the cultivars in terms of their microsporogenesis schedule. The same order was found in all three years. This order also indicates the yield reliability of the cultivars. Endodormancy ended between January 10th and 25th in the buds of the earliest cultivar ‘Pinkcot’, but not until February 5-10th in the latest cultivar ‘Harlayne’. Three of the cultivars had faster flower bud development than the control, in the order ‘Pinkcot’, ‘Orange Red’ and ‘Harcot’. Growing these cultivars thus involves greater risk than for ‘Gönci magyar kajszi’ in Hungary, due to their rapid winter flower bud development. Some cultivars found to have slower flower bud development than ‘Gönci magyar kajszi’; ‘Litoral’, ‘Harogem’, ‘Comandor’, ‘Sirena’ and ‘Harlayne’ – thus these cultivars can be grown more reliably.
