Chris is interested in producing the mostnew plants in the shortest time period. What is the best propagation method for him to accomplish his goal?
Budding
Cutting
Grafting
Tissue Culture
Jacob learns a disadvantage of propagating using cuttings is that when cuttings are removed from the parent plant, the:
cuttings’ absorption process stops.
cuttings are cut off from their source of water.
parent plant needs more light.
parent plant needs additional fertilizer.
Victoria is careful to study the temperature, moisture, and seed viability for the plants she plans to grow. These are factors that affect:
germination rates.
hardwood cuttings.
softwood cuttings.
tree grafts.
Hannah is hardening off some tomatoes started in the greenhouse. Which is she reducing to harden off her plants?
Fertilizer and Air
Lime and phosphate
Humidity and water
Soil and fertilizer
Jamie has a tray of marigold seedlings she started from seed. She transplants the seedlings from the seedling flat to cell packs when the:
first mature roots appear.
first true leaves are on the plant.
plants are two weeks old.
seedlings are 6 inches tall.
Jenny needs to construct some beds to use for rooting azalea cuttings. How deep should the rooting media be?
1 Inches
2 Inches
4 Inches
10 Inches
Christy enjoys mound layering her prize-winning azalea. Which is true of her mound layering technique?
The plant has to be dug and separated first.
A trench has to be dug for each stem being propagated.
Only one inch of bark has to be removed.
Soil has to be heaped up around the plant.
Victor joins a new variety of pecan tree to some rootstock he has grown from seeds. Which propagation method does he use?
grafting
hardwood cutting
softwood cutting
division
Caroline is careful to use tissue culture in laboratory conditions that are aseptic. Therefore, the laboratory environment is:
dirty
humid
pretty
sterile
Uneek is making leaf cuttings. She must be certain that she cuts the leaf:
margin
petiole
vein
stomate
Jennifer is using Rootone on her poinsettia cuttings. She knows that an advantage of using hormones on cuttings is that they:
aid in photosynthesis.
decrease water needs.
keep the leaves from dropping.
speeds root development
Samantha is cutting the iris rhizome in sections. This method of asexual propagation in which plants are broken or cut into smaller pieces or clumps and are planted to form new plants is:
division
grating
layering
seeding
Janet uses stem cuttings to propagate her prize-winning azaleas. What is the besttime of day for Janet to take the cuttings from her azaleas?
early evening
early morning
mid day
early afternoon
Neil is sexually propagating some plants. Which plant parts will he use?
leaves
roots
seeds
stems
Callie is propagating her African violet by taking leaf cuttings. She is confident that leaf cuttings will work because she is using:
axillary buds
herbaceous plants
stem tissue
woody plants
How can Tracie reduce stress on greenhouse-produced seedlings at transplanting time before removing them from the greenhouse?
Fertilize the seedlings more
harden off seedlings
Mist the seedlings often
water seedlings more
Andrew selects a unique azalea plant. The propagation method that he uses to rapidly increase the number of identical plants is:
grafting
leaf cuttings
seeding
tissue culture
If Dave has a bag of fescue that has a seed germination rate of 80%, he can expect
20 out of 100 seeds to germinate
all the seeds to germinate
80 out of 100 seeds to germinate
80 out of 200 seeds to germinate
Renee needs about 1,000 petunia plants. If the seed germination rate is 50%, what is the minimum number of seeds she should sow?
50
1000
1200
2000
