Phenological network of CHMI includes three types of phenological observation (field crops, fruit crops and wild plants). Subsequent fruit trees were chosen into vealuation: Apple (Malus domestica Borkh.), European Pear (Pyrus communis (L.) Gaert.), Apricot (Armeniaca vulgaris Lam.), Sour Cherry (Cerasus vulgaris L.) a Common Walnut (Juglans regia L.).
Different generative and vegetative phenological phases were processed during the period 1991-2010 in relation to synoptic situations.
