Germination of seeds
The germination of seeds is influenced by a combination of environmental factors. These factors can vary depending on the plant species, but some common conditions that affect seed germination include
Water
Adequate water is crucial for germination. It helps soften the seed coat and activates enzymes that initiate germination. However, excessive water or waterlogged conditions can lead to fungal growth and seed rotting.
Temperature
Different plants have specific temperature requirements for germination. Some seeds germinate best in cool temperatures, while others require warmer conditions. Temperature influences the speed of germination and the metabolic processes involved.
Oxygen
Oxygen is essential for aerobic respiration, which provides the energy needed for germination. Seeds require oxygen to break down stored nutrients and support early growth. Poor aeration, such as waterlogged soils, can limit oxygen availability and hinder germination.
