What Australian plants require their seeds to be heated in order to germinate?
Banksia seeds require fire to germinate, while many species of acacia (wattle tree) also need heat in order to germinate. Flannel flower seeds also benefit from bushfires, while Boronia requires smoke to germinate.
Do all seeds germinate immediately after they are dispersed?
No, in fact some seeds lay dormant for many years and others are triggered by heat (only germinate after a forest fire).
Do all seeds germinate immediately after they dispersed?
No, in fact some seeds lay dormant for many years and others are triggered by heat (only germinate after a forest fire).
Why do seeds need wild fires to survive?
Some species are adapted to wild fires. The seeds can not germinate until they have been exposed to fire. The seeds are NOT damaged by the fire and after the fire they sprout taking advantage of the space the fire has left and the minerals in the fire's ashes.
How long do seed take to germinate?
Between 1-7 days, usually around day 2.

What does the fire do to assist the trees to reproduce?
It forces the seeds (such as pinecones) to open so they will be allowed to germinate. The heat activates them to open because the seed thinks it is warm enough to let the seeds germinate. And let the plant reproduce.

What is the adaptation of a wattle?

Seeds dispersed by fire and their plants name?
Jack Pine is one of the plant dispersed by fire
Which plant has seeds that might be stimulated to grow after a fire?
Pine tree
You've obtained the seeds from a plant you would like to grow in your yard You plant a few of them but they do not germinate What type of treatments might promote the germination of these seeds?
It depends on the seeds. Some seeds, like alfalfa seeds and clover seeds, need to be coated with a specific rhizomidous bacteria that helps break down their hard outer coating. Other seeds require scarification or fire or even being soaked in water to soften or break apart that hard outer shell of the seed. Many other seeds do not require any of the above, and simply need a specific depth of soil to be planted in, a little bit of water, sunlight, and time.
