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

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 cuttings

• Layering

• Softwood cuttings

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

• grafting

• layering

• seeding

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

• 1,000

• 1,200

• 2,000

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

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.

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

• late afternoon

• mid-day

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.

• speed root development.
