How to Stimulate Rose Bud Mutation
Let's learn about the related experience of how to stimulate rose bud mutation that most people have in flower planting.
How to Stimulate Rose Bud Mutation
Stimulating rose bud mutation can be achieved by chemical methods, such as applying colchicine, or by physical methods, such as using lasers and radiation. These methods can cause somatic cell mutation in plants, i.e., bud mutation, and after selection, new varieties with excellent traits can be cultivated.
1. -- Colchicine --
Applying colchicine to the seeds, terminal buds, axillary buds, or growing points of the bulbs of roses can induce bud mutation. The function of colchicine is to inhibit the formation of spindle fibers, resulting in polyploid cells. Dilute colchicine to about five hundred times and apply it to the mentioned parts, once in the morning and once at noon, to cultivate diploids into polyploids.
2. -- Physical Methods --
Radioactive substances such as X-rays, lasers, and cobalt-60 can inhibit the formation of spindle fibers in the early stages of cell division, causing them to mutate into polyploids. However, the direction of physical methods is uncertain, and not all treated materials can be doubled according to people's wishes, so later breeding of varieties is necessary.
3. -- Definition of Bud Mutation --
Bud mutation is a type of somatic cell mutation, where the somatic cells of the plant's bud meristem mutate, commonly doubling, usually manifested in traits such as branches, leaves, flowers, fruits, and phenophase, maturation period, etc. Using buds or mature branches that have undergone bud mutation and propagating them asexually can cultivate new varieties with more excellent traits.
4. -- Application of Bud Mutation --
Bud mutation is when genetic factors within somatic cells mutate, causing different traits to be expressed. These traits may be valuable to humans, for instance, in plants, the organs of polyploid plants are generally larger than those of diploids and are sterile. These variations can increase yield for humans and characteristics such as flowers not needing to be emasculated are considered desirable traits.
