RESEARCHES ON GENETIC RESISTANCE TO APRICOT VARIETY BERGERON TO FROST FROM WINTER

Published in Scientific Papers. Series B, Horticulture, Volume LXII
Written by Constantin PĂUN

The research was conducted in a orchard of apricot aged 7 years, located at 50 km away from Bucharest. Trees planted at a distance of 4x4m were studied during the vegetation season paying particular attention to resistance to low temperature. In the winter of 2013, temperatures in winter decreased to -20 degree C and produced losses of flower buds. In the spring of 2014 the 'Bergeron’ variety bloomed well, 100% of flower buds being resistant to negative temperatures from winter. In 2015 was a warm winter but the temperature decreased in January to -29 degree C and the trees suffered a thermal shock. Following, resistance to frost decreased and the percentage of flower buds affected was 98.2%. Production losses were very high and vegetative buds were not affected by frost and the trees were properly vegetated grew normally. In January of 2016 were recorded temperatures of -25 degrees C associated with very cold wind, the flower buds were affected in 100%. In 2017 'Bergeron’ variety was not affected.
