Grafts and Wounds; Unique Storage Organs
| Question | Answer |
|---|---|
| How does grafting result in a chimera? | 2 different genotypes growing together in the same plant |
| What is the difference between grafting and budding? Why would one be preferred over the other? | Budding only uses one scion versus the whole stem; T-budding is done when the plant is actively growing (the bark is "slipping") |
| What types of plant habit can be produced through grafting onto special rootstock? Why are these habits desirable? | A "weeping" type scion for flowering trees for aesthetic purposes |
| Reasons to graft | Perpetuate genotypes that don't root from cuttings; change cultivars; repair damaged plants; take advantage of rootstock characteristics; produce specialized trees |
| Reasons not to graft | If the plant roots easily; doesn't require special rootstock; amount of expertise, time, and expense |
| Why may a graft not be successful? | Plant type isn't conductive to grafting; Not compatible; wrong time of year and season; environment; technique |
| What type of graft is recommended for trunk damage? | Bridge grafting |
| Shortly after the plant is wounded, what is the first response of the plant cells adjacent to the wound? | Rapidly exude compounds like suberin to protect from water loss and pests; stimulated to divide and protect the wound |
| When a wound heals, what cells are stimulated to divide? | Parenchyma cells in the cortex |
| What types of tissues must be formed from the parenchyma callus if the graft is to be successful? | Xylem and Phloem |
| What is a tuber? | Underground stem, storage organ |
| What is a bulb? | Subterranean, highly condensed stem, adventitious roots, 2 types: imbricate and tunicate |
| What is a corm? | Underground, compressed stems, adventitious roots |
| How are tunicate bulbs different from imbricate bulbs? | Tunicate bulbs have a papery covering and mostly leaves; Imbricate bulbs consist of scales |
| Crowns can often be divided by gardners for easily producing new plants. What structures allow this? | Adventitious roots, stem grows radically |
| What is a rhizome? | Underground stems, adventitious roots, grow horizontally, used in grasses for rapid colonization from the crown |
| What is a stolon? | Above ground stems, not for storage, adaptations to reduce local competition with mother plant and spread genetic material |
| Your friend intends to bud-graft propagate numerous new alder cultivars that are in limited supply to another alder tree. What type of grafting or budding would you recommend? | T-budding |
| A rabbit has girdled a maple tree trunk and you must repair the damage that it has done. What type of grafting or budding would you recommend? | Bridge grafting |
| Monocots are difficult to graft because: | vascular bundles are scattered in the stems. |
| A chimera is defined as: | Two different genotypes growing on a single plant |
| During grafting, a callus bridge forms: | from parenchyma cells. |
| An important condition for successful grafting and budding is: | Proper after care |
| Which grafting technique avoids wounding the plant? | All grafting techniques wound the plant. |
| Shortly after the plant is wounded, the surviving cells produce: | Suberin |
