When pruning or doing cuttings tools should be cleaned using ___clorox__________or
___lysol_______.
Plants that are propagated asexually have genetic information from only one parent and are
commonly called ___clones__________.
Before taking seedlings or young plants to the garden to be planted, they should be gradually
___hardened____________ off.
When planting seeds or taking cuttings, what two things are most important?
_temperature_________ and ___light_______
It is extremely important not to plant landscape plants too deep, however, your manual
specifically mentions burying the stem of tomato plants when planting them. Why is this
possible with tomato plants?
Tomato plants can send out roots or branches from anywhere along its stem. By planting

__T__
moisture.

True or False: Layering is the rooting of a stem while it is still attached to the parent plant.
The process of providing a cold, moist period to satisfy seed dormancy (after ripening) is called?
a.
b.
c.
d.
stratification
aerification
crushification
scarification
Buds that arise from unexpected locations, such as buds arising from root tissue, are known as?
a.
b.
c.
d.
precocious buds
apical buds
radical buds
adventitious buds
What is the primary difference between sexual propagation (seeds) and asexual propagation
(cuttings)?
Asexual propagation involves the taking of a vegetative part of one plant to create
a new plant, which will be a clone of the parent plant. Sexual reproduction is the
propagation of new plants by sowing seeds, which are created by union of pollen and
egg to mix genes of two parent plants. The new plant will not be an exact replicate of the
parent plants
Name three (3) different methods of asexual (vegetative) propagation.
Cuttings, layering, budding, grafting.
Identify the following two terms as they relate to grafting.
Scion – A piece of detached twig or shoot that contains two or three buds. A single bud is
known as budding.
Rootstock – also called stock or understock, the part of the graft that forms the root
system of the grafted plant.
Do most vegetable and annual seeds require a pretreatment to germinate? No, they
generally do not require scarification, stratification, or any special pretreatment to break
dormancy.
