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

Let’s use Begonia as our first example
Begonia tuber-hybrida
![Page 12: Seeds & Seed Propagation](https://reader036.vdocument.in/reader036/viewer/2022081505/568166dc550346895ddb06e1/html5/thumbnails/12.jpg)
Begonia Fruit
![Page 13: Seeds & Seed Propagation](https://reader036.vdocument.in/reader036/viewer/2022081505/568166dc550346895ddb06e1/html5/thumbnails/13.jpg)
Begonia seeds are extremely small!1,000 seeds are shown next to the coin.
![Page 14: Seeds & Seed Propagation](https://reader036.vdocument.in/reader036/viewer/2022081505/568166dc550346895ddb06e1/html5/thumbnails/14.jpg)
Pelleted Begonia seeds are much easier to see and mechanically sow. Pelleted seeds are round.
![Page 15: Seeds & Seed Propagation](https://reader036.vdocument.in/reader036/viewer/2022081505/568166dc550346895ddb06e1/html5/thumbnails/15.jpg)
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](https://reader036.vdocument.in/reader036/viewer/2022081505/568166dc550346895ddb06e1/html5/thumbnails/18.jpg)
Raw Marigold seed is long and thin with a prominent tail.
![Page 19: Seeds & Seed Propagation](https://reader036.vdocument.in/reader036/viewer/2022081505/568166dc550346895ddb06e1/html5/thumbnails/19.jpg)
Detailed Marigold seed has the tail removed. Detailed seed is much easier to handle and
mechanically sow.
![Page 20: Seeds & Seed Propagation](https://reader036.vdocument.in/reader036/viewer/2022081505/568166dc550346895ddb06e1/html5/thumbnails/20.jpg)
These are coated Marigold seeds. The coating improves visibility and helps the seeds flow better
through a mechanical sower.
