Explain the methods to overcome seed dormancy.

(N/A) Seed dormancy can be broken through natural processes or human-induced activities:
$1$. Mechanical Scarification: If the seed coat is impermeable, it can be broken by rubbing with sandpaper or using mechanical pressure to create pores.
$2$. Physical Methods: Vigorous shaking of seeds can also help in breaking dormancy.
$3$. Microbial Action: In nature, microbial activity helps in degrading the seed coat, thereby breaking dormancy.
$4$. Digestive Tract: Passing seeds through the digestive tract of animals can soften the seed coat due to the action of digestive enzymes.
$5$. Chemical Treatment: Dormancy can be broken by using chemicals like $Gibberellic \text{ } Acid$ $(GA_3)$ or nitrates, which neutralize the effect of growth inhibitors.
$6$. Environmental Factors: Altering environmental conditions such as light, temperature, and chilling treatments can effectively break seed dormancy.
