Unit 7 Flashcards
The most commonly used in commercially important method of asexual reproduction is propagation
Via cuttings
To root cuttings require essentially the same conditions that seed need to germinate
Moisture , oxygen and warmth
Cuttings may begin to grow roots without light especially in the first stages of ________formation
Callus
Asexual reproduction by cuttings
Set my hardwood stem cuttings, wood cutting should be able to bend
This type of wood is very soft and breaks with a snap
Soft wood cutting
First step in making the cutting wood is to find a_________
Has made 2 to 6 inches of new growth, is not wilted or dried
Parant plant
When taking the cutting from the parent plant ….
Immediately place it in water, place a label in the container with the cutting
This current season growth may be from the tip of a branch or a shoot that is growing from the _____of the plant
Base
Check to be sure that the wood is of proper maturity or hardness in that the plan is not _____ or ________
Wilted or dried out
___ is the best time to take a cutting from the parent plant
Early morning
Softwood or semi hardwood cuttings or made with plants have _____ on them
Leaves
Leafs help the propagator keep the cuttings right side up the point_____
Upward
It is necessary to know the top of the cutting because the stem must be placed in the routing medium with the bottom end pointed __
Down
To avoid confusion cut the branches from the parent plant at a _____angle on the bottom end and straight across at a ___ angle on the top
45 , 90
When preparing the container and Rooting medium
Any container at least 4 inches deep
must have holes in the bottom for drainage
Must be sterile or free from living organisms
A mixture of 1/2 horticulture_____ to help loosen the structure of the routing medium and 1/2 course_____ Moss provides a good medium
Perlite, Sphagnum
Pure perlite or pure sand is ____________
Satisfactory
The high percentage of Pete Moss recommended for pots and flat sealed with plastic with hold too much moisture under mist there by withholding sufficient oxygen and possibly causing the cuttings to ____
Rot
Place level and firm that makes medium
Leave 1/2 inch between the top of the container in the medium
Leveling allows water to spread evenly over the surface
Water the medium until water runs through the container bottom
Filling the medium
After soaking the Pete Moss and water squeeze out the excess water before mixing and placing in the_____
Container
____water is recommended to thoroughly Moisten Pete Moss and soilless planting media
Hot
Inspect the cutting work for proper maturity
Makes three or 4 inch cuttings as possible from each stem or shoot
Include two or three buds on each cutting
Making the cuttings
_____ shears must be used so that a clean cut is made
Pruning
It is NOT important to cut at or near a _____unless the plant stem is hollow
Node
Treat the cutting with_____ hormone
Rooting
Immediately place cuttings in the routing medium
Space so that leaves do not overlap
Press the medium around the cutting very firmly
Do not water them using powder hormones
Treating with hormones and inserting in medium
Use either the previously prepared label or prepare a new one
Variety name, date including the day month and year
Add the rooting hormone
Please label on the rooting container
Labeling
New cutting has least but no roots
Leafs lose moisture through
transpiration more quickly than can be drawn up through slanted cut end
Keep relative humidity close 100 percent
Use a greenhouse if available if one is not available
Enclose containers with polythene plastic
Place containers out of direct sunlight
Controlling the atmosphere
Check the cuttings
Hold the cutting and tug gently
If the cutting does not easily slip out roots are developing
If no roots close the container and wait 7 to 10 days
When the cuttings have root ball measuring two or 3 inches across hard and them off in a preparation for trans-planting
Rooting
