Examples of short-cycle crop-production schedules. See Chapters 4 and 5 for details of propagation and forcing techniques. Potted roses grown in containers from start to finish are produced by using the smaller flowered cultivars with 1 of 2 methods, the short-cycle or the long-cycle method. For the short-cycle method, actively growing liners or pre-finished plants are commonly used (Figure 1 and cover photo). Depending on plant size, liners can be potted into pots 4 to 6 inches (10 to 15 cm) in diameter.
If a rose is only known in commerce by the trademarked name) (Elliot, 1991; Higginbotham, 1992). There are commonly many conflicting opinions on the naming of roses and use of trademarks (Higginbotham, 1992). Revisions to the code are currently being considered to solve these problems, but cooperation and compromise will be needed to end the confusion (Higginbotham, 1992). It is hoped that these issues can be resolved to the benefit of scientists, plant breeders, plant producers, and consumers alike.
Plants can be sprayed frequently with a fog nozzle. Plants can also be covered with white opaque polyethylene or wet burlap, but covers should be removed when new leaves begin to expand (MacKay, 1985). Black or clear plastic should not be used because of the possibility of excessive heat buildup. Forcing begins immediately after potting and generally takes 6 to 8 weeks. Top-grade plants (see Chapter 4) should be used because smaller sizes may require pinching, which delays finishing. All types of structures from cold frames to fully equipped, state-of-the-art greenhouses can be used for forcing; however, because temperature strongly influences forcing time (see below), the degree of control that is required must be considered.
