abstract 0611007036 issue 61 pp. 460 – 463 24.09.2010 ru 1772
We studied the architecture of the root system of apple tree varieties (Idared, Golden Delicious, Rei-nette Simirenko, Florina grafted on the rootstock M9), planted in 2003, according to the scheme 4 x 1 and formed by type: Russian spindle (k) Knip Baum, Bee Baum, Sollux. We found out that on mid loamy soil with drip irri-gation, the bulk of the roots located at a depth of 10 - 60 cm regardless of the type of crown formation. Large (more than 3 mm) roots of Reinette Simirenko and Florin varieties of trees in age of seven have penetrated to a depth of 60 - 80 cm while forming Russian spindle and Knip Baum crown-type and their length and their weight was 5 – 8% of the overall performance
