In Italy, as long as orange trees were propagated by grafts, they were tender; but after many of the trees were destroyed by the severe frosts of 1709 and 1763, plants were raised from seed, and these were found to be hardier and more productive than the former kinds.
Dan tore Brady's uniform open then pulled out a small emergency medical kit and slapped skin grafts over the two wounds.
Shaking with fear for Brady, she watched them cut through the skin grafts and transfuse blood then jump his heart.
For the propagation by grafts of stove and greenhouse plants the process adopted is whip-grafting or a modification of it.
All grafting of this kind is done in the propagating house, at any season when grafts are obtainable in a fit state - the plants when operated on being placed in close frames warmed to a suitable temperature.

When removed from the plant and treated as cuttings or grafts, such sports may be perpetuated.
It will have been gathered from what has been said that seeds cannot always be depended on to reproduce exactly the characteristics of the plant which yielded them; for instance, seeds of the greengage plum or of the Ribston pippin will produce a plum or an apple, but not these particular varieties, to perpetuate which grafts or buds must be employed.
During winter, grafts may be conveyed long distances, if carefully packed.
