Whole-root grafts. â When roots of seedling trees are used for grafting, just as they come from the soil, except perhaps for trimming and slight shortening, the resulting trees are said to be "whole-root ; To make such trees the graft is placed at the crown, so the term "root graft" is erro- neously used, the proper term being "crown ; The roots are by no means "whole"; first, because a good deal has unavoidably been left in the ground when the seedling was dug, and second, because the roots must be shortened so the finished graft will not exceed nine inches and thus be too long for best handling in the nursery. The seedling roots are either single tap-roots four to six inches long, or shorter where several branches occur near the crown. Usually the lat- eral roots are cut oS close to the main root, otherwise the grafts are difficult to make and to handle both in bundling and in planting. 304. Piece-root grafts are made from cions six or seven inches long and bits of root only three or two inches long. First grade, or number one, apple seedlings often make three and sometimes four pieces, though the average would probably be not more than 250 piece stocks to the 100 roots as bought. Number two seedlings will rarely reach 150 pieces to the 100 roots. When stock is costly or. Please note that these images are extracted from scanned page image
