| Abstract:
The extremely cold winter of 1986–87 in Veria (North Greece) generally caused little damage except in a few areas. It was the second cold spell in March (minimum temp -8.5°C) which although it was less severe than that of December (minimum -12.5°C) caused the most frost damage possibly due to dehardening effects of the warmer weather between. Frost damage to the flower buds of 12 peach cultivars on 4 peach rootstocks is tabulated: The samples were taken close to the pink bud stage (17 March) and the cultivars Early Crest, May Crest and Frederica (Katerina) were the most frost hardy, while the cvs Fairlane, Firebrite and Loadel were more sensitive to frost. Apart from the effect of cv on susceptibility, peach cvs on GF 677, Damas GF 1869 and St. Julien 655/2 had greater damage than those on wild seedlings. In addition interactions between cv x Rootstock have been found. | |
