Why are humidity and temperature in germination chambers critical?
Seed germination is a process that is highly sensitive to environmental conditions, where humidity and temperature play a crucial role. Germination chambers are designed to precisely control these parameters, ensuring an optimal environment that favours uniform and healthy seed development.
Importance of humidity control in germination chambers
Relative humidity (RH) is essential to maintain proper hydration of the seeds and ensure their ability to germinate.
- Optimal RH levels:
Generally between 70% and 90%, depending on the type of seed.
Prevents dehydration and ensures efficient gas exchange, key to cellular respiration.
- Impact of excess or deficit of moisture:
Excess: Favours the growth of moulds and pathogens, affecting seed viability.
Deficit: Can lead to failure of the imbibition process, where seeds do not absorb enough water to initiate germination.
Role of temperature in germination
Temperature affects the speed of germination and the success rate of the process:
Ideal temperature ranges:
- Range from 20°C to 30°C for most species.
- Modern chambers allow precise settings with minimal variations to simulate day and night conditions.
Effects of thermal control:
- Promotes enzyme activity necessary for cell division.
- Simulates seasonal changes for germinating species that require periods of vernalisation or cold exposure.
Benefits of advanced germination chambers
