Comparative analysis of sweet cherry cultivars on their ecological and biological indicators

Sweet cherries are slightly more demanding than sour cherries. It is grown in warmer areas around the world. The relative ecological values obtained for varieties by extensive data collection differ from leading descriptions. Warm and demanding. woody parts tolerate cool of winter quite well, flower buds damaged spring frosts. Its water demand medium, case 550 mm annual rainfall, it adorns well on loose soils with good nutrient supply. Airy ground, neutral soil (pH 5.5-7.5) optimal, but not suitable strongly calcareous, stagnant, stagnant groundwater. From start ripening, sudden stormy winds birds can cause great damage. Highlighting world’s study (Bing, Rainier, Chelan, Van Burlat) (Iezzoni et al., 1991, Faust & Surányi, 1997) - according to biological values, most popular mainly they differed other based TB KB. Open pollination it, productivity exceeded overall variety average precisely because breeding objectives. Certainly, analysis historical varieties, oldest landscape local help further pomological-ecological research.
