| | Grafting |
 | | The rootstock used for cleft grafting should range from 1 to 4 inches in diameter and should be straight grained. | | | These cuts on the rootstock and scion must be the same length and have the same slope so that a maximum amount of cambial tissue will make contact when the two halves are joined. | | | In contrast to cleft grafting, this technique can be applied to rootstock of larger diameter (4 to 12 inches) and is done during early spring when the bark slips easily from the wood but before major sap flow. |

| | Peach seed commonly used for rootstock production include `Lovell' `Halford,' `Elberta,' and `Rutgers Red Leaf.' `Nemaguard' is sometimes used for nematode resistance and `Siberian C' is occasionally used to provide winter hardiness and moderate dwarfing of the scion cultivar, but it does not survive well in Kentucky. | | | Use Pyrus calleryana seedlings as the rootstock, bud the desired scion cultivar as low as possible on the stock, and plant the finished tree so that all of the P. | | | Peach rootstocks are best grown from seed planted in the fall. |

| | Citrus Rootstock Usage in the Indian River Region |
| | Broader plantings and longer experience with the "best" new rootstocks will inevitably identify problems and limitations for at least some of them, but it is likely that a few of the current advanced selections will prove attractive and will be used for a substantial proportion of Indian River citrus production in the next twenty years. | | | A wide range of new citrus rootstocks is being developed by both the University of Florida and the USDA-Horticultural Research Laboratory in Ft. Pierce, FL, and promising rootstocks from other areas are regularly brought to Florida for evaluation. | | | Finally, while sour orange was a superior rootstock on all Indian River citrus soil types, no other rootstock has been proven as an excellent choice for grapefruit on high pH soils or those that contain substantial clay, making rootstock selection difficult where these soils are present. |

| | Sweet Cherry Rootstocks |
| | Rootstocks are evaluated for their influence on survival, tree growth, flower density, yield, fruit size, soluble solids, and suckering. | | | Of particular interest is new rootstock evaluation, characterization of rootstock influence on flower bud density, Armillaria root rot resistance, virus sensitivity of rootstocks, rootstock incompatibility with commercial scion varieties, and gene expression changes associated with rootstock induced dwarfing. | | | With some of these rootstocks, there is a potential problem of excessive cropping levels when grafted with very productive scion cultivars. |

| | Budding Fruit Trees and Ornamental Plants |
| | The rootstock is grown from seed using the techniques described on the Growing Plants from Seed page. | | | Remember, a rootstock is a small tree seedling, and in most cases the seedlings are planted in the field, and the budding is done right in the field, where the plant is actively growing. | | | If you have 100 different crabapple rootstocks that you grew from seed, you can grow many different varieties of flowering crabapples by inserting different varieties of buds into these rootstocks. |

| | About the Vine |
| | The scion and rootstock graft is callused for 60 to 90 days in a high humidity environment at 78 to 80 degrees F, then planted in a nursery row and grown for one year, sold and transplanted as a Dormant BenchGrafted Vine. | | | However, if a rootstock is not needed it should not be used because if the vine freezes to the ground, it is very difficult to regraft the vine. | | | A third system for establishing vines with a rootstock is to plant rootstock rootings in the spring, grow them in the vineyard for one year and Field Graft the vines one or two years later. |

| | Choosing one or the other of these rootstocks does not influence the type of fruit yielded by a tree, but for Northern growers it can have a big effect on how winter-hardy the tree is, how well it grows, and whether it produces a crop. | | | A well-pruned apple tree on Antonovka rootstock, when grown in Zones 3-5, will be equivalent to a ``semi-dwarf'' tree in size (10-12 feet at maturity), and it will have many advantages. | | | ``Standard'' means only that Antonovka is not a dwarfing rootstock; it will not limit the growth and thus the ultimate size of the tree, but rather will allow it to grow freely to its full size, about 12-15 feet. |
