Which statement describes 21st-century rose production that involves bending or arching?

• A. Grafting
• B. Seed propagation
• C. Air layering
• D. Bending / arching

Answer: (D)

In modern rose production, the method that involves bending or arching is a form of layering. Here, a cane is bent down and a portion of it is buried in the soil or medium so that roots form along the buried section. Once rooted, this new plant can be separated and grown as a clone of the parent. This vegetative propagation is fast and reliable, producing uniform plants without the genetic variation that comes from seed. It differs from grafting, which joins a scion to a rootstock, and from air layering, which roots a stem above ground without necessarily forming an arch. So, bending or arching captures the arch-layering approach used to multiply roses efficiently in contemporary production.
