SBV - Seed Saving
Transcript of SBV - Seed Saving
WHY DO WE NEED TO SAVE OUR SEED?
KEEPING STRAINS PURE
WHEN TO PICK
AFTER THE HARVEST
DRYING & STORAGE
Select Your species to insure genetic purity (true to type)
Cull out the
Select how many plants you will be taking seed from
Mark plants with traits that are favorable to your context
"The best time to pick seed
is in the morning
after the dew has dried away."
Cucurbits - when stem has browned that connects to fruit
Legumes - when pot is beginning to turn brown
Goosefoots - when stem and seed has browned
Brassicas - when pods have browned but not opened yet
Alliums - when flowers have started to brown off
Asteraceae & Apiaceae familys - when flowers have dried and stem is browning
Solanums - when fruit has completely ripened (with exception of potatoes which is when plant has died off and skin is hard)
Do your research and get a clear understanding of how the plant you are looking to cultivate grows.
hot temperatures often give lots of male flowers
flower wilts over 2 days
grow best in warmer places
low growing habits with tendancys to climb
CUCURBITACEAE IMPORTANT OLD WORLD SPECIES
Cucumis Sativus - Cucumbers
Citrullus Lanatus - Watermelon
Cucumis Melo - Melon
CUCURBITACEAE IMPORTANT NEW WORLD SPECIES (most of which originated in north america)
cucurbita maxima - jarrahdale, jap/kent pumpkin, turks turban - rambiling vine up to 4m or more
cucurbita pepo - zucchini, button and spaghetti squash - low growing bush varietys with exceptions of some gourds
cucurbita moschata - butternut and quensland blue
cucurbita argyrosperma - gourd
cucurbita ficifolia - gourd
What strategies will you use to make sure your seed remains true to type next season?
Distance and barriers
vigor of plant
size of fruit/yield
drought resistance (ability to go
with less water than usual eg; irrigation)
earlier yielder/late yielder
positive or contextually favorable habit traits
Out of direct sunlight
Dry, cool environment with good airflow
Silica satchels work well for keeping seed dry
Screen out any bad seed
