Evolution of climatic conditions and its potential impact on sweet cherry in RBIP Holovousy Ltd.
It can be assumed that commercial production of fruit crops will be impacted by climate change. In the Research and Breeding Institute of Pomology Holovousy Ltd. (RBIPH), there are continuous meteorological records since 1955. RBIPH carries out observations in the form of services for the Czech Hydrometeorological Institute and we present an overall analysis of the evolution of climatic conditions in relation with key periods in the sweet cherry growth cycle. The average annual temperature for the whole 55 year period is 8.4°C. The lowest annual temperature (6.2°C) was in year 1956 and on the contrary, the highest in years 2007 and 2008 (10.1°C). There is a visible increase in average annual temperatures in quinquenniums beginning from 1990-1994. Measurement of weather parameters that affect sweet cherry is relevant for serious interpretation of experiments carried out in the field. In particular, the course of temperatures in April and May affect sweet cherry from the point of view of late spring frosts damaging flowers and fruits. Furthermore, precipitation from April to July have a high impact on fruit size and undesirable fruit cracking. There is a visible increase in average temperatures in May in quinquenniums beginning from 1985-1989 and in April in quinquennium 2005-2009. Increasing trend of average annual and month temperatures is in accordance with climate changes and global warming. In contrast to the tendency to warming, a long term trend is hardly discernible in the case of precipitation.
