Climate Change Effects on Apple Phenology and Phenometry in an Apple Gene Bank Plantation of Hungary

The trees observed were grown at Ujfeherto, Eastern Hungary in a gene bank with 586 apple cultivars. Each of the cultivars was monitored for its dates of: the beginning of bloom, main bloom and the end of blooming and ripe phenophasis separately. We analysed the statistical features, frequency distribution of these apple fruit tree phenophasis date and phenometrical parameters of apple fruit and its correlation between the meteorological variables separately. The purpose of phenometry is to examine the measurable parameters of the plants in order to follow up the consequences of weather processes. In the present study, the interactions between the above mentioned phenomena are presented and numerically defined.
