Across
- 3. are thickened roots that contain large amounts of stored food
- 7. are underground stems that grow horizontally and produce stems on the bottom and stems on the top
- 12. is accomplished in the spring, is very similar to simple layering except that a stem is covered by soil at two or more points
- 13. is actually a form of grafting; in fact, it is sometimes called bud grafting
- 14. are tiny bulbs
- 15. is to completely remove the bark and cambium around the plant
- 17. begins with the planting of a rooted layer in soil
- 18. is a method of propagation in which parts of the plant are cut into sections, each capable of developing a new plant
- 19. is a process by which two different plants are united so that they grow as one
- 21. is a very solid compact stem with nodes and internodes
Down
- 1. is a plant structure containing many parts but primarily composed of leaf scales
- 2. is the newly installed shoot or top of the plant
- 3. the mother plant is bent to the ground and buried in a trench
- 4. is a method of propagation in which natural structures produced by certain plants are removed from the parent plant to become new plants
- 5. is a very effective way to graft evergreens such as the colorado blue spruce
- 6. is a method of asexual propagation in which roots are formed on a stem or root while it is still attached to the parent plant
- 8. is kept wrapped in waterproof paper so that it does not dry out
- 9. is used on roses as well as other plants
- 10. a process that eliminates burying part of the parent plant in soil; instead part of the plant is slit or girdled
- 11. a branch of from a parent plant is bent to the ground where it is partially covered at one point with soil
- 12. is used most often in top working trees or grafting to a rootstock that is considerably larger than the scion
- 16. is the seedling or plant used as the bottom half of the graft
- 20. is a swollen end of an underground side shoot or stem
