What are two environmental factors that can trigger germination?
Environmental factors such as temperature, light, pH, and soil moisture are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer- gence.
What are the main environmental factors that affect germination?
According to VCE Authors Diane Relf and Elizabeth Ball, “There are four environmental factors which affect germination: water, oxygen, light, and temperature.” Water is important because it brings the seed to life. Seeds need a continuous supply of water during germination.
What factors contribute to germination?
Major Factors Necessary for Seed Germination in Plants (Internal and External Factors)
- Water: Germination cannot occur unless and until the seed is provided with an external supply of water.
- Oxygen:
- Temperature:
- Light:
- Other factors:
- Vitality:
- Longevity or viability:
- Dormancy:
What are the environmental and external factors necessary for germination?
ADVERTISEMENTS: The below mentioned article will highlight the factors affecting seed germination. Some of the important factors are: (1) External factors such as water, oxygen and suitable temperature. (2) Internal factors such as seed dormancy due to internal conditions and its release.
What are 4 factors that affect germination?
There are four environmental factors that affect seed germination: Water, Light, Oxygen, and Heat.
What are the four environmental requirements for seed germination?
Four environmental factors affect germination: light, water, oxygen, and temperature. All plants have specific germination requirements based on ecological adaptations and the environmental cues that trigger germination for that species. Light quality and duration can influence germination.
What are the five environmental factors?
Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites.
What are the four environmental requirements of seed germination?
What factors affect seed germination experiment?
Several variables might affect the germination, these variables include light, temperature, water, soil type, and air quality.
What are the essential factors for seed germination?
Water, temperature, oxygen, and light (only for some seeds) are the essential conditions for the germination process. The absence of one or more of these affects the sprouting of seeds. Similarly, the maturity of an embryo, seed viability, and dormancy are internal factors that affect this process.
What are the 4 environmental factors?
What are the two factors of environment?
the two factors are temperature, amount of sunlight also water soil.
