depends on the specie, some seeds have to germinate within a few weeks or months or they will die; others can remain dormant for up to 20 years before conditions can be right and they will germinate.
there was a instance a while back where a 2000 year old date seed that was found in an archaeological site was successfully germinated
Persistent seed bank.
Seeds can stay in the soil for a long time due to their protective outer coatings or seed coats that help them resist harsh environmental conditions, such as changes in temperature and moisture. This allows them to remain dormant until conditions are suitable for germination. Additionally, some seeds have mechanisms that inhibit germination until specific triggers, like exposure to light or fire, are present.
Yes, acidic soil can affect the germination of seeds by inhibiting the availability of certain nutrients essential for seed germination and seedling growth. It can also impact the activity of soil microorganisms that play a crucial role in the breakdown of organic matter and nutrient cycling, further affecting seed germination.
Mung bean (monggo seed) grows best in loamy soil that is well-draining and nutrient-rich. While it can still grow in sandy soil, it may need extra nutrients and water because sand drains quickly and does not hold nutrients well. Adding compost or organic matter to sandy soil can help improve its fertility and water retention.
Loosening the soil before planting helps improve aeration, drainage, and root penetration for the seed. It creates a softer environment for the seed to establish roots and allows moisture and nutrients to reach the seed more easily as it germinates and grows.
They remain in the soil and decompose.
Epigeal germination is when the cotyledons emerge above the soil surface during seed germination. Hypogeal germination is when the cotyledons remain below the soil surface during seed germination.
Persistent seed bank.
It take no longer for a seed to grow in organic soil than it does in non-organic soil. It totally depends upon the amount of moisture, sunlight and nutrients that are available.
2 or 3 days.
Rat poison can remain active in soil for several weeks to months, depending on the type of poison used and environmental conditions.
either about 3 weeks but they grow mostly in soil
Yes, an avocado seed will grow if planted in soil.
Glyphosate can remain active in the soil for several months to a year, depending on factors such as soil type, temperature, and moisture levels.
Trees such as acacia, locust, and catalpa have long seed pods. These trees contribute to the ecosystem by providing food and shelter for wildlife, helping with soil erosion control, and adding nutrients to the soil when their pods decompose.
Yes, you can successfully seed grass on clay soil by preparing the soil properly, choosing the right grass seed, and providing adequate water and nutrients for the grass to grow.
The aims of seed bed preparation are to create a favorable environment for seed germination and plant growth by breaking up soil clumps, incorporating organic matter, leveling the soil surface, and promoting good seed-to-soil contact. This process helps to ensure uniform seed placement, good seed-soil contact, and optimal conditions for seedling emergence and establishment.
