Szalay, L. | Pedryc, A. | Papp, J.
The greatest hazard of apricot production in Hungary today lies in winter and spring frost damages. In winter flower buds are the most vulnerable parts of apricot trees. There are a relatively great number of data available on the frost hardiness of apricot varieties on the basis of field experiments. However, alterations in cold hardiness cannot be traced by the estimation of natural frost damages. For that purpose, laboratory methods are required. In our work frost tolerance of flower buds of 20 apricot varieties was determined by artificial freezing test.
