10 AG: Seed Germination

What is the primary reason mature seeds have relatively little moisture?

• To enhance growth

• To prevent decay

• To increase weight

• To improve color

When do seeds usually mature?

• Spring

• Summer

• Autumn

• Winter

What is required for respiration to start metabolism in seeds?

• Carbon dioxide

• Nitrogen

• Oxygen

• Hydrogen

What effect does over-watering or poor drainage have on seedbeds?

• Increases oxygen supply

• Causes oxygen supply to become limited

• Enhances germination percent

• Reduces water absorption

What is the result of stimulating the cell membranes and metabolic activities in seeds with diluted acid solution?

• Decreases the germ rate

• Increases the germ rate

• Stops the germination process

• Has no effect on germination

Does acid treatment work on all seeds?

• Yes, it works on all seeds

• No, it does not work on all seeds

• It works on most seeds

• It works on very few seeds

What is the purpose of seed dormancy?

• To delay germination until conditions are favorable

• To speed up the germination process

• To increase seed size

• To enhance seed color

Which factor is crucial for breaking seed dormancy?

• Light exposure

• Temperature changes

• Water availability

• All of the above

What is the main function of the seed coat?

• To provide nutrients

• To protect the seed

• To enhance germination

• To increase seed weight

What is the role of enzymes in seed germination?

• To inhibit growth

• To break down stored food

• To increase seed size

• To change seed color
