Definition
| scion is the bud from a plant that is grafted onto a new rootstock |
|
|
Term
|
Definition
-Take advantage of rootstock characteristics
-repair damaged plants
-Increase growth rate of seedlings
-Produce trees w/ specialized forms
-Perpetuate clones that're usually hard to root
-Create new, desirable cultivars |
|

Term
|
Definition
-Requires experience in technique
(Skill in choosing materials)
(Timing is critacle)
(Experienced workers are expensive)
-Needs to have a good reason
-No cheaper/better way to do it |

Term
| Responses to wound in plant |
|
Definition
-Exude compounds like suberin that creates protective layer
-Cells are stimulated to divide to cover and protect wound (callus) |
|
|
Term
| Steps of wounding in grafting |
|
Definition
1) callus originates from parenchyma in pith, xy/phloem in scion and rootstock
2) callus grows into callus bridge
3) cells in bridge differentiate into xy/phloemand cambium
|
|
|
Term
| Five criteria for successful graft |
|
Definition
1) The rootstock and scion must be compatible
2) The cambial layers of the stock and scion must be closely aligned
3) The graft must be done at the appropriate time
4) Grafts must be protected from drying
5) The grafted plant must receive proper post-graft care |
