description |
After severe winter frost, an examination was initiated of frost damage suffered by Idared and Golden
Delicious clone B. The cultivars differed significantly in the differentiation intensity, the hare of damaged
differentiated buds, but not in share of damaged undifferentiated buds. In both cultivars the bud damage was
more intensive on long bearing wood than on spur, regardless differentiation grade. The interaction between
the cultivar and the bearing wood was insignificant. The flower bud differentiation was better in Idared, but it
also suffered more frost damage than the Golden Delicious clone B with differentiated buds, but not than that
with undifferentiated buds. In both cultivars frost damage increases with increase of differentiated flower
buds (R2=0.759; P≤0.001). The fruit set was within the limits of expectation only on the spurs of the Golden
Delicious clone B, which showed strong tendency towards fruit set on long bearing shoots. In 2000, the yield
of the cultivars was almost equal, as the result of thinning due to the frost damage on Idared. |
