3 Basic Parts

Embryo Food Storage Coverings

Embryo

Part of the seed that “germinates” and becomes the new plant.

Germination Requirements of Seed

Moisture Favorable temperatures Oxygen

Light and Seed Germination

May be required for germination in some species: Small-seeded annual plants

Seed Enhancements

Page 11: Seeds & Seed Propagation

Let’s use Begonia as our first example

Begonia tuber-hybrida

Page 12: Seeds & Seed Propagation

Begonia Fruit

Page 13: Seeds & Seed Propagation

Begonia seeds are extremely small!1,000 seeds are shown next to the coin.

Page 14: Seeds & Seed Propagation

Pelleted Begonia seeds are much easier to see and mechanically sow. Pelleted seeds are round.

Page 15: Seeds & Seed Propagation

Multi-pelleted Lobelia seed. Each pellet contains several seeds.

Mechanical seed sower for sowing plug trays in the greenhouse $$$$$

How about Marigold?

Page 18: Seeds & Seed Propagation

Raw Marigold seed is long and thin with a prominent tail.

Page 19: Seeds & Seed Propagation

Detailed Marigold seed has the tail removed. Detailed seed is much easier to handle and

mechanically sow.

Page 20: Seeds & Seed Propagation

These are coated Marigold seeds. The coating improves visibility and helps the seeds flow better

through a mechanical sower.
