Seed Propagation Review

What is the term for rapid uptake of water by a seed to hydrate inner tissues during seed germination?

• radicle

• plumue

• lag phase

• imbibition

The average number of seeds that germinate over the 5- and 10- day periods

• photodormancy

• seedling percentage

• germination rate

• scarification

What is the term/phase associated with little or no water uptake, but with many cellular activities in seed germination?

• imbibiton

• lag phase

• radicle protrusion

• maturation drying

What are the 3 conditions that must be met in order for seed germination to occur?

• seed must be viable

• germination rate

• imbibition

• environmental conditions are favorable

• dormancy conditions are overcome

What are the environmental conditions that are needed for germination?

• water

Germination occurs based on how much light is received by the seed.
