Seed Handling, Seed Storage and Commercial Seeding
Plant Propagation

3 General Fruit Classifications
Dry – Indehiscent Dry – Dehiscent Fleshy
3
Dry - Indehiscent Fruits that do not split open when ripe.
Ex: Maple, Elm, Ash and Oak
4
Dry – Indehiscent Fruits
Ash Samaras Maple Schizocarps
5
Dry – Dehiscent Fruits Fruits that split open when ripe.
Ex: Redbud, Honeylocust and St. Johnswort.
6
Dry – Dehiscent Fruits St. Johnswort Capsules Redbud Pods
7
Fleshy Fruits with a fleshy pericarp.
Ex: Crabapple, Viburnum, Dogwood, Callery Pear and Serviceberry.
8
Fleshy Viburnum Drupes Callery Pear Pomes
9
Seed Collection and Handling
10
Dry – Indehiscent Fruits
Hand Collect Fruit Purchase Seed (Sheffields, NY state) Dry and de-wing (if necessary) Store and plant later Provide necessary seed treatments Sow
11
Dry – Dehiscent Fruits Hand Collect Fruit Purchase Seed
Dry; allow fruits to split open Separate seed from fruit Store and plant later Provide necessary seed treatments Sow
12
Fleshy Fruits Hand Collect Fruit Purchase Seed Maceration
Flotation or Fermentation to separate seed from fruit Dry Store and plant later Provide necessary seed treatments Sow
13
Seed Storage
14
2 Kinds of Seed Short-lived seed. Medium to long-lived seed.
15
Short-lived Seed Remains viable in storage for 1 year or less.
Ex: Poplar, Maple, Willow, Elm, Hickory, Birch, Oak, Beech, Walnut and Buckeye. Storage: High Humidity/Low Temperatures
16
Medium to Long-lived Seed
Remains viable in storage for 1 year or longer. In some cases 15 or more years. Ex: Most conifers, fruit trees, vegetables, flowers, grains, legumes, geranium and morning glory. Storage: Low Humidity/Low Temperatures
17
Outdoor Commercial Seeding
18
Successful seeding depends upon the following…
Good quality seed (viable). Overcoming seed dormancies. Providing the proper environment for seed germination. Proper temperature Moisture Aeration (oxygen)
19
Steps in preparing an outdoor seedbed for spring planting…
#1 Prepare a raised bed about 4 feet wide.
20
Raised Bed for Seed Sowing
21
#2 Bed sanitation. Methyl bromide (fumigant)
Vapam (granular-activated by water) Basamid (granular-activated by water) After sanitation it is critical that the beds be allowed to “air-out” several days prior to seed sowing.

#3 Sow the seed. Broadcast Rows Weed control issues.
24
#4 Roll the seed. Good seed-to-soil contact. More even germination.
Un-rolled seedbed Rolled seedbed
25
#5 Cover seeds with coarse sand.
Helps eliminate problems associated with damping-off.
26
#6 Provide light shade. Helps reduce transpiration.
Eventually remove shade and acclimate seedlings to brighter/drier conditions.
27
Hoops can be used to provide support for shade cloth
28
#7 Maintain moisture! Never let the seed bed dry out.
Use frequent, light irrigations to maintain moisture.
29
#8 Provide proper aftercare.
Continued watering Fertilization Weed control
30
