Q. What is the role of dermal tissue?
Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots). Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss.
Q. Which is the primary function of the plant tissue?
Complex Tissues. Tissues composed of more than one cell type are generically referred to as complex tissues. Xylem and phloem are the two most important complex tissues in a plant, as their primary functions include the transport of water, ions, and soluble food substances throughout the plant.
Q. Which function is mostly performed in the fleshy tissue parts of a plant rather than in the tissue that make up the upper layer of leaves?
storage
Q. What is the dermal layer of a plant?
Epidermis, in botany, outermost, protoderm-derived layer of cells covering the stem, root, leaf, flower, fruit, and seed parts of a plant. The epidermis and its waxy cuticle provide a protective barrier against mechanical injury, water loss, and infection.
Q. What plants can you air layer?
Air layering can be used to propagate large, overgrown house plants such as rubber plant, croton, or dieffenbachia that have lost most of their lower leaves. Woody ornamentals such as azalea, camellia, magnolia, oleander, and holly can also be propagated by air layering.
Q. Can I use potting soil for air layering?
Make a 1½-inch wound to start the air layering process. Wrap the wound with sphagnum moss or soil, and cover it with plastic wrap. After placing the soil and plastic wrap around the wound, tie a rubber band at each end to form an airtight seal. Sphagnum moss (or potting soil in a pinch)
Q. When can air layer be removed?
Air layers are ready to be removed from the parent plant when the air- layering bags have been permeated by developing roots. Normally this will take 6 to 12 weeks, but may take as long as 2 years.
Q. Can you air layer any tree?
Most plants can be air layered and, even if no rooting takes place, the original plant is not damaged by the process since you do not remove the donor material until it has produced roots. Herbaceous tropical indoor plants and woody outdoor ornamentals are good candidates for air layering and may include: Rhododendron.
Q. Can you air layer without rooting hormone?
To successfully air layer a plant, you will need to gather: a clean sharp knife, sphagnum moss, polyethylene film, aluminum foil, and twist ties, twine or electricians tape. Rooting hormones may improve rooting success but are not necessary.
Q. How long will it take for roots to appear after air layering a plant?
The air-layer is then left alone for 3-7 weeks to allow roots to form. The air-layer should be checked after three weeks for root formation. Air layering is a good method of reproducing good-sized plants in one year.
Q. How long do roots stay in air layer?
about three months
Q. What are advantages and disadvantages of layering?
Disadvantages of Layering: 1) This method of propagation is limited to plants which form growing points readily. 2) It is difficult to produce large number of plants through this method. In other words, this method does not use propagation material economically.
Q. Which is better air layering or grafting?
Grafting is considered as a highly useful technique of propagation. Layering is considered as less useful technique of propagation when compared to grafting. With grafting you can get more varieties from a single plant. Layering results in one type of offspring.
Q. How do you graft a mature tree?
Bark grafting can be used on larger rootstock than any other grafting method, so it is the best method to change the variety of a mature tree; the rootstock can be 4 to 12 inches in diameter. Bark grafting is done in early spring when the bark can easily be slipped from the wood, but before there is major sap flow.
