EFFECT OF SOIL FATIGUE ON FROST RESISTANCE OF ONE-YEAR OLD APPLE-TREE SHOOTS, TOPAZ CULTIVAR
Zofia Zydlik | Piotr Zydlik
The presented studies have shown the effect of soil fatigue on the decrease of resistance to low temperatures in one-year old apple-tree shoots. The highest frost resistance was demonstrated by the shoots of apple-trees grown in localities so far not utilized for fruit-tree cultivation.In a replanted apple-tree orchard, the plantation of trees in the grass inter-rows of the old apple orchard did not cause any explicit increase of frost resistance by the apple-tree shoots.
