What is seed germination?
Click to flip
Seed germination is the process by which a seed develops into a new plant.
Click to flip
Why is water essential for seed germination?
Click to flip
Water activates the enzymes that break down stored nutrients, enabling the seed to grow.
Click to flip
What role does temperature play in seed germination?
Click to flip
Temperature influences the rate of germination, with each seed having a specific optimal range.
Click to flip
How does oxygen availability affect germination?
Click to flip
Oxygen is necessary for aerobic respiration, providing energy for seed growth.
Click to flip
What is the impact of light on germination?
Click to flip
Light can either stimulate or inhibit germination, depending on the seed type.
Click to flip
What is dormancy in seeds?
Click to flip
Dormancy is a period when seeds delay germination until conditions are favorable.
Click to flip
How do seeds overcome dormancy naturally?
Click to flip
Environmental factors such as temperature, moisture, and sometimes fire can break dormancy.
Click to flip
What is the role of growth regulators in seed germination?
Click to flip
Growth regulators can promote or inhibit germination by affecting hormonal balances.
Click to flip
How does soil pH impact seed germination?
Click to flip
Soil pH affects nutrient availability and enzyme activity crucial for seed germination.
Click to flip
Why does the seed coat affect germination?
Click to flip
The seed coat protects the seed but must be broken or permeable for germination to occur.
Click to flip
What is the significance of nutrient availability in germination?
Click to flip
Nutrient availability supports the growing seedling until it can photosynthesize independently.
Click to flip
How does salinity affect seed germination?
Click to flip
High salinity can inhibit germination by affecting water uptake and causing physiological stress.
Click to flip
What is imbibition in the context of seed germination?
Click to flip
Imbibition is the process of water absorption by the seed, crucial for triggering germination.
Click to flip
Can seed covering structures be a factor in germination delay?
Click to flip
Yes, hard seed covering structures can physically restrict water and gas exchange, delaying germination.
Click to flip
What are the critical phases of seed germination?
Click to flip
The phases include imbibition, activation of metabolism, radicle emergence, and seedling establishment.
