| Abstract:
Every ten year apricot-trees of the cultivar Hungarian Best, grafted on seedlings of the local semiwild apricot-tree and Myrobolane, have been totaly turned up of roots. From each parcel and layer roots have been taken out and measured by length and classified by thickness. Results: The total weight of the underground and overground organs of the apricot-trees is amounting 142, 1 kg, and at Myrobolane 90, 9 kg. It means that the apricot-tree has a more vigorous rootstock than Myrobalane. The largest mass and length of the sceletal roots are placed inside 1 m2 around the tree, and going to the outskirts their density decreases (r= -095 to 097). Diminutive fibrosness roots at Myrobalane are distinguished with a rightmeasurable horizontal and vertical disposition by the whole life's space, while at the wild apricot-tree their density is largest around the tree, and decreasing to the outskirts. The area in the row is richer in roots in comparison to that within row space. The root system at both rootstocks is extending to the depth of 75 cm, where digging of the soil has been done before the planting of the orchard. On the surface layer which is cultivated there are no roots. | |
