PHENOLOGICAL AND CLIMATIC SIMULATION OF THE LATE FROST DAMAGE IN CHERRY AND SOUR CHERRY IN ROMANIA

The probability of late frost damage is estimated for sweet and sour cherry orchards.
The probability of damage was calculated as the simultaneous occurrence of a susceptible phenophase and the critical temperature.
A database of phenological observations was used for bud burst, green tip, early blossom and petal fall in sweet cherry (‘Germersdorf’ cultivar) and sour cherry (‘Crisana’ cultivar) orchards for a 29 year period (1970-1976, 1982-2003) together with weather data taken from a longer period.
The probability of damage exceeded 3% in sweet cherry and 4% in sour cherry for five day periods between March 11 and April 25 in the Pitesti – Maracineni area.
To extend the applicability of these studies to areas with no phenological observations, a package of multiple regression equations was developed which could simulate the phenological dynamics until the end of bloom.
