. The nursery-book; a complete guide to the multiplication of plants ... Gardening; Plant propagation. ISO GRAFTAGE. It is indisputable that there is great difference in the root system between the ordinary budded tree and the ordinary root-grafted tree. The roots of the root-grafted tree, as it leaves the nursery, are comparatively shallow and horizontal, and are generally prongy and strongly developed on one side or another of the tree. It is well known, of course, that different varieties of apples develop a different root system in the nursery row, but the same variety ordi- narily has a very different root development when propa- gated by budding and by common root-grafting. The writer has seen this difference so uniformly for so many years, and upon such an extent and variety of stock, both east and west, that he has no hesitation in positively affirming that, as generally grown, the root system of budded trees is unlike that of root-grafted trees. This difference in root development pro- ceeds from the method of cutting the stock. In other words, if the pieces of roots were budded they would undoubtedly develop the same sys- tem of roots that they do when grafted. The philosophy of it will become apparent upon a moment's reflection. The short piece of root has fewer side rootlets than the whole or long root. It is these side rootlets which develop into the main branches of the root system. The root system of the piece-root must, therefore, be shallower at first start than that of the whole root, because the axis is shorter. Moreover, these side rootlets do not develop simultaneously upon all sides of the main axis. They are scattered along the axis. 144. New roots A section or piece of the root may contain ""/^^ ««<'<'/ ^ a piece-root, rootlets only on one or two sides of the axis, and as these rootlets grow the system becomes one-sided. There is still another reason for the prongy and one-sided character of the root-system, of piece-roots.
