Part V Additional Concept Flashcards
What is polyembryony?
The occurrence of multiple embryos in one seed.
How does polyembryony benefit plant reproduction?
Increases the chances of seedling survival.
Define apomixis.
Asexual reproduction through seeds without fertilization.
What is the result of apomixis?
Genetically identical offspring.
What plants commonly use apomixis?
Mango, citrus, and grasses.
What are the advantages of apomixis?
Maintains desirable traits in plants.
How does sexual propagation promote species adaptation?
Allows plants to adapt to environmental changes.
Why is seed viability important?
Determines whether seeds can still germinate.
What factors affect seed viability?
Moisture, temperature, age.
How does moisture content influence seed storage?
Too much moisture reduces viability.
What is seed vigor?
The seed’s ability to germinate and establish.
Why is seed vigor important in agriculture?
Ensures strong and healthy plants.
What are hybrid seeds?
Seeds from cross-pollinated plants.
How are hybrid seeds produced?
By controlled breeding of different plant varieties.
Why are hybrid seeds popular in agriculture?
They offer higher yields and disease resistance.
What is seed certification?
Quality control process for seeds.
Why is seed certification important for farmers?
Ensures high-quality and reliable seeds.
What is seed priming?
Pre-treatment of seeds before planting.
How does seed priming benefit germination?
Speeds up germination and enhances uniformity.
What is the role of seed banks in conservation?
Preserve seeds for future planting and biodiversity conservation.
