|185||: Plant Species whose germination is improved by Smoke|
|"Smoke" contains a butenolide compound produced by certain plants when heated, it speeds up or starts the germination of seeds from many different genera.|
|720||: Fire Resistant Plants|
|Different classes of resistance: some grow back, some don't burn, a few have highly inflammable leaves that leave the rest of the plant intact, some trees don't have lower branches.|
Some knowledge about growing from seed is necessary to germinate even the easiest seeds.
Most seeds require humidity to germinate, even desert plants like
require that their growing medium remains moist until germination.|
Most seeds require oxygen to germinate, if buried too deep in their growing medium, or if the medium is too wet,
the seeds may not get the oxygen they require.
Pyracantha crenulata seeds will usually germinate in 40-180 days, even under good conditions germination may be erratic.
Pyracantha crenulata seeds need to be "overwintered" before they will germinate.
Stratification; cold treatment or vernalization. Seeds of some species need just a couple of weeks, others 3 months. Seeds can be stratified in dampened peat or sand, in a plastic box or bag at 4°C or 5°C in a refrigerator. The seeds should not be frozen or in a wet medium. Very small seeds can be sown on the surface of their growing medium, in pots sealed in plastic bags, and kept in the 'fridge. Many vernalized seeds need light to germinate when they are sown in the "Spring".
(Pre-chill for 6 weeks).
