dc.description.abstract | The aim of the paper is an attempt to present the relationships
between sour cherry (Prunus cerasus L.) blooming time, climatic conditions
and spring frost risk in western Poland (Great Poland Lowland). Air
temperature indices from meteorological stations in Przybroda and Poznań
for the period 1985-2010 representing contemporary climate warming were
used. ‘English Morello’ sour cherry phenological records for the period
1985–2010 were collected at the Research Station of Poznań University
of Life Sciences located in Przybroda. The earliest end of blooming was
observed on 2nd of May 1999, and the latest one on 26th of May 1987.
The average period of sour cherry blooming was between 30th April
and 12th May. During 50% of the years the blooming period lasted from
11 to 15 days. Mean monthly temperature in Przybroda varied from -1.1ºC
in January to 19.6ºC in July. A significant relationship between the beginning
date of cherry blooming and the beginning of the thermal vegetation period
was found. Variability of the index explained more than 50% of variability
in the first dates of cherries blooming (coefficient of determination
R2 = 0.505 is significant on the level p < 0.05). The beginning of blooming
was also significantly (p < 0.05) correlated with mean April temperature,
which could explain about 43% of variability in the dates of the first bloom. An increase in April temperature by 1.0ºC caused earlier blooming
by about 2.8 days. During the period of 1985–2010 a significant increase
in April temperature was observed (in Poznań 0.79ºC per decade). It had
an effect on advanced dates of the beginning of sour cherry blooming
of about 3 days per decade. In 26 of the years the last frost occurred 4 times
(15% of seasons) during the blooming phenological phase or later
in Przybroda. Frost occurred 10 days before blooming started and during
blooming in 54% of the years. | pl_PL |
