Fruit
- Seed-bearing structure in flowering plants that is formed from the ovary after flowering
- Means by which flowering plants disseminate their seeds
Seed
- Mature ovule that comprises an embryo
Diff. parts of monocot seed
- Cotyledon: helps convert starches stored in the endosperm to usable form
- Endosperm: food storage for seedling (starch)
- Plumule: embryonic leaf
- Radicle: embryonic root
- Seed coat: protects seed
Diff. parts of dicot seed
- Cotyledon: Provides food for germinating seedling
- Plumule/Epicotyl : Embryonic leaf
- Hypocotyl : Embryonic stem
- Radicle: Embryonic root
- Seed coat: protects seed
4 basic types of fruits
- Simple (banana)
- Aggregate (strawberries)
- Multiple (pineapple)
- Accessory (apples)
Dehiscent fruits
Split open (beans)
Indehiscent fruits
Do no split open (walnut)
Carpal levels of fruit
Exocarp (can be eaten)
Mesocarp (can be eaten)
Endocarp
Seeds
Pericarp (can be eaten)
Asexual propagation
New plants or offsprings that are genetically identical
Clone
An organism or a group of genetically identical organisms derived from a single parent organism through asexual reproduction
Advantages to asexual propagation
Maintains genetic uniformity of a plant
What is the plant growth hormone used for promoting root initiation?
IBA
6.What are the techniques for asexually propagating plants?
- Grafting/budding (joining plant parts)
- Layering
- Tissue culture
- Cuttings
What are the three tissue types used in asexual propagation?
- Dermal
- Vascular
- Ground tissue
Vernalization
The cooling of seed during germination in order to accelerate flowering
What temp conditions are needed?
34 - 45 degrees
Graphical tracking
Helps growers forecast crop height, when they’ll flower
