Hello mate,
Here is your answer,
Seed Scarification - Seed scarification involves breaking, scratching, or softening the seed coat so that water can enter to stimulate the seed germination process. ...
Seed Stratification/ Vernalisation - Seeds of some trees and shrubs from the temperate zone do not germinate unless they are exposed to chilling temperatures.
Answer:
Methods to break seed dormancy are:
Scarification: It is softening of seed coat using sand paper or knives or chemicals like alcohol or acid.
Stratification: It involves layering of seeds in specific medium and then exposing them to warm stratification at 15°C to 20°C which is followed by cold stratification at 0°C to 10°C.
Removal of germination inhibitors: This includes washing the seeds thoroughly.
Hormonal treatment: Hormones such as gibberellins or auxins can be used.
