  1. Sexual plant propagation

  2. Propagation of plants from seeds Composition of seeds Seed coat- outside covering which protects embryonic plant endosperm- stored plants food, and nourishes embryonic plant during germination

  3. Propagation of plants from seeds embryo (embryonic plant)- a new plant that is developed as a result of fertilization, and during germination it extends its roots and seed leaves (cotyledons) to form a new plant.

  4. Propagation of plants from seeds Germination media favorable pH supply of plant nutrients firm and porous sterile and free from foreign materials

  5. Indirect seeding Seeds sown in a separate place from where they will eventually grow to maturity Transplanted one or more times before reaching permanent growing area

  6. Flats made of: wood, plastic, and metal have drainage holes in bottom seeds generally sown in rows. * we will use flats with individual pots

  7. When to seed important in business to have saleable product ready at market time

  8. Sowing seeds follow package directions to determine planting distance cover with sprinkling of moist sphagnum or peat moss label:name, variety, and date sown

  9. Watering water from bottom if watering from top be careful to avoid washing seed out or too deeply into soil

  10. Germination 65-70 degrees soil temperature retain humidity cover with glass or plastic

  11. Germination some seeds require three days of darkness prior to germination cover with newspaper instead of glass

  12. Germination water with a fine mist or from the bottom

  13. Transplanting seedlings following germination plants develop seed leaves - cotyledons allow plant to grow until first true leaves are present before transplanting

  14. Transplanting seedlings hold seedlings by true leaves not by the stem with thumb and forefinger bruised stem could cause plant death

  15. Transplanting seedlings don’t shake off media from roots can cause them to dry out too much

  16. Transplanting seedlings plant about 2 inched apart insert at depth a little deeper than they were grown before gently press media around roots water with gentle stream to settle soil around roots

  17. Direct seeding planting seeds directly into the permanent growing area most economical media-soil prepare by loosening soil and removing all large clumps

  18. Direct seeding add manure, grass clippings, or compost to improve soil structure chemical treatment disease prevention insect prevention

  19. Direct seeding Germination Requirement same as indirect seeding.

  20. Treatments of seed for Germination Same seed won’t readily germinate soak in water or acid bath to soften seed coat scratch with sand paper allows water into seed

  21. Treatments of seed for Germination dormant stage moist and cold below 37 F bury in moist sand and keep cool refrigerate

  22. Treatments of seed for Germination Alternate wetting and drying Presence of light Darkness Follow package instructions Fire or extreme heat- Jack Pine
