1) Why is a mist of water applied to cuttings at regular intervals between dawn and sunset?
A
to create an environment inhospitable to fungi and bacteria
B
to provide plant cells with protection against direct sunlight
C
to initiate enzyme activity necessary to stimulate root formation
D
to reduce water loss from the plant tissue through transpiration
2) Why should flowers on the stem of a cutting be removed before sticking?
A
to deter potential insect pollinators
B
to direct energy to root development
C
to use for ornamental purposes
D
to stimulate reproductive growth
3) What method of propagation may involve portions of stems, leaves, or roots removed from the plant?
A
grafting
B
layering
C
budding
D
cuttings
4) What is asexual propagation?
A
reproduction involving the stigma, ovule, or ovary
B
reproduction using vegetative parts of a plant
C
reproduction through genetic recombination
D
reproduction through the union of two sex cells
5) Which are the ideal conditions for propagation by cuttings?
A
a dense, moist, sterile medium; high humidity; full sun; cool medium
B
a dense moist, wet medium; low humidity; shade; bottom heat
C
a loose, moist, sterile medium; high humidity; shade; bottom heat
D
a loose, moist, highly fertile medium; low humidity; full sun; cool medium
6) What is an advantage of asexual propagation in the horticulture industry?
A
Plants produced benefit from genetic contributions from both of the parent plants.
B
The offspring produced are more likely to be resistant to disease and insect pests.
C
Outstanding characteristics of plants are assured to be passed on to the offspring.
D
Only a single fertilization is required rather than the normal double fertilization.
7) What term describes the practice of placing cuttings into a medium?
A
sowing
B
grafting
C
budding
D
sticking

A
They have the highest food production and the capacity to produce new plantlets.
B
They have superior heterozygote advantage than less healthy leaves.
C
They have immature root buds that develop once leaves are removed.
D
They are generally the largest, most attractive, and blemish-free.

fleshy roots
D
adventitious roots
12) Why would a plant propagator choose to use the layering technique to propagate a plant?
A

Occasionally new cultivars with improved genetics are discovered.
C
