| Abstract:
The Czech Republic has a rich tradition in growing plum trees. Since the beginning of the last century plums are the most important fruit species in the Czech Republic. Plums are cultivated on a growing area of about 2056 ha and hold second rank just behind apples. Growing areas of plums are slowly expanding every year. Plums are grown for direct consumption and for processing. The plum fruits have a high nutritional value and are, from this point of view, the most valuable fruit species. Their chemical composition and nutritional value are considerable, depending on the species, cultivar, degree of ripeness, climate, soil, and growing conditions. Asian cultivars of plums are practically unknown for Czech growers. In this study 27 cultivars of European and Asian plums have been evaluated in Lednice in South Moravia. A total of ten characteristics have been evaluated. The highest values of vitamin C have been measured in ‘Mirabelle de Nancy’ (82.92 mg kg-1) and ‘Santa Rosa’ (Prunus salicina) (81.62 mg kg-1). Cultivar ‘Santa Rosa’ contained, in addition to high levels of vitamin C, the most sugar (23.1%). The ‘Burbank’ cultivar (P. salicina) contained the most fiber (7.15 g kg-1). Furthermore, antioxidant capacity was determined using the method of DPPH. The highest antioxidant capacity was measured in intergenic hybrid M56 (P. armeniaca × P. cerasifera) with 675.57 mg kg-1. | |
