Theshort piece of root has fewer siderootlets than the whole or long is these side rootlets which developinto the main branches of the rootsystem. The root systetn of the piece-rootmust, therefore, be shallower at first start thanthat of the whole root, because the axis isshorter. Moreover, these side rootlets do notdevelop simultaneously upon all sides of themain axis. They are scattered along the axis. 144 New rootsA section or piece of the root mav contain ontheendoj ^, ^ , . , • <• piece-root. rootlets only on one or two sides of the axis,and as these rootlets grow the system becomes is still another reason for the prongy and one-sidedcharacter of the root-system of piece-roots. The piece of. ROOT-GRAFTED AND BUDDED TREES. 151 root is essentially a cutting. Every gardener knows thatroots seldom start symmetrically from all sides of the endof a cutting. Fig. 144 (from a photograph) shows youngroots springing off from the end of acutting. All three of them start fromnearly a common point. It is a one-sided or unsymmetrical system. shows two root-grafts, drawn fromlife, as they had grown at the expira-tion of two months after they were plantedin the nursery. They show the same pecu-liarities of root development as the cuttingdoes in Fig. 144. The reader now desires to know whythe same one-sided method of root growthdoes not take place at the end of the rootin the budded tree, for these stocks aredressed or trimmed—that is, the tips of theroots are cut off—before they are set in thenursery row. The whole question turnshow much the roots of the stocks arecut back. If only the very tip iscut off,
