Across
  1. 1. used to join a smaller scion to a larger stock part
  2. 5. a cut portion of a stem that contains a terminal bud or lateral bud
  3. 6. a short piece of stem with two or more buds
  4. 7. used when the plant’s bark is thick, such as on pecans and walnuts
  5. 11. hoods that filter bacteria and fungal spores from the air
  6. 12. are made from woody broad-leaved plants with new shoots
  7. 15. Sterile
  8. 17. is similar to grafting except that the scion is reduced to a single bud with a small portion of bark or wood attached
  9. 19. is accomplished by bending a branch to the ground, slightly cutting or wounding the stem, and covering the wounded portion with 2 to 3 inches of soil
  10. 20. consists of a leaf, petiole, and a short piece of stem with a lateral bud
  11. 21. a genetic duplicate
  12. 23. the grower severely prunes the parent plant to stubs that are 2 to 4 inches high. The stubs are then covered with soil
  13. 27. consists of a leaf blade or leaf blade with petiole attached
  14. 28. a method of asexual propagation in which roots form on a stem while it is still attached to the parent plant
  15. 29. made from soft succulent growth
  16. 30. the propagation of new plants using only the vegetative parts of the parent plant
  17. 31. plants from which cuttings are removed
  18. 32. involves girdling the stem about 6 to 9 inches from the growing tip. Root-inducing hormone is applied to the cut area, and moist sphagnum moss is placed over the exposed area. Plastic is wrapped and tied around the moss to maintain moisture. After roots develop, the top part of the plant is cut just below the rooted area.
  19. 33. small pieces of plant material during the first stage of tissue cultures
Down
  1. 2. The roots that form on cuttings
  2. 3. shoots that are developed from tissue cultures
  3. 4. taking buds from one plant and inserting them under the bark of the rootstock
  4. 6. removal and planting of vegetative plant structures that can be removed intact from the parent plant
  5. 8. a group of cells with no particular function
  6. 9. The stock and the scion are cut at a slant angle. The whip or tongue is created by making a single cut 1/2 inch deep into the sloping cut. The scion tongue cut is inserted into the rootstock tongue cut. The cambium layers of both cuts are lined up. The graft union is bound with tape.
  7. 10. the lower portion of the graft
  8. 13. One of the most common and simplest methods of asexual propagation
  9. 14. the plant roots or the entire plant may be cut into sections to make two or more plants from the original plant
  10. 16. the process of connecting two plant parts in such a way that they will unite and continue to grow as one plant.
  11. 17. is similar to cleft grafting in that it joins smaller scion wood to a larger rootstock
  12. 18. involves digging a shallow trench near the parent plant. An entire branch is bent over, placed in the trench, and then covered with 2 to 5 inches of soil
  13. 22. culture is a very technical method of asexual propagation that involves the growing ofplant cells or tissues on artificial media under sterile conditions
  14. 24. are taken from one-year-old growth, deciduous, or evergreen plants
  15. 25. a gel that contains water, sugars, nutrients, and plant hormones to support and promote plant growth
  16. 26. A common term used for increasing the numbers of plants
