Varietal response of pear to gibberellin treatment after flower damage by spring frosts



Varietal response of pear to gibberellin treatment after flower damage by spring frosts



Byulleten' Vsesoyuznogo Ordena Lenina Instituta Rastenievodstva imeni NI Vavilova (103): 19-22



In 1979 spring frost (-5 deg C) before flowering damaged 40% of flower buds in the pear Beurre d'Hardenpont and 95-100% in the cvs Cure and Beurre Bosc. Treatment with GA3 at 0.01% during flowering significantly increased fruit set in the cvs Cure and Beurre d'Hardenpont but had no effect on Beurre Bosc.
