What do seeds need in order for germination to occur?
When it comes to light requirements for germination, there are three main categories of seeds:
- Seeds that need light to germinate (they should not be covered by soil)
- Seeds that need thin covering to germinate (you should cover them with a thin layer of soil)
- Seeds that germinate in darkness or light (ideally you should bury them at a depth of twice the seed’s diameter)
Do large seeds germinate faster than small seeds?
Smaller seeds have been shown to germinate faster (peas, see ref.2). Big seeds often produce seedlings which have a higher growth rate (they grow faster) than seedlings from smaller seeds but this doesn't necessarily mean that they will go on to produce a bigger plant overall.
How to germinate old seeds?
Use small jiffy starter blocks or a light soil:
- Dilute 10ml (roughly one tsp) of Fulvic acid per litre (33 oz) of water.
- Scuff the outer shell of the seed with some sand paper. ...
- Use a lightly carbonated water. ...
- Use a light enzyme or seed booster, Plagron Nutrients has a very good one.
- Finally if all else fails use an Exacto knife to slightly slice the seed open down the spine of the seed. ...
Will old seeds still grow?
There is a good chance that those old seed packets will have a high percentage of seeds that will germinate just fine. Most seeds, though not all, will keep for at least three years while maintaining a decent percentage of germination. And even a group of very old seeds may have 10 or 20 percent that still sprouts.
What is the oldest seed to have germinated?
date palm seedScientists in Israel have confirmed that an ancient date palm seed retrieved from the rubble of Masada and successfully germinated is about 2,000 years old. That makes it the oldest seed ever to sprout, beating the previous well-documented record holder, a lotus found in a dry lakebed in China, by about 700 years.
What is the oldest type of seed plant?
The oldest known seed plant is Elkinsia polymorpha, a "seed fern" from Late Devonian (Famennian) of West Virginia. Though the fossils consist only of small seed-bearing shoots, these fragments are quite well-preserved.
How Old Can seeds be and still germinate?
There is a good chance that those old seed packets will have a high percentage of seeds that will germinate just fine. Most seeds, though not all, will keep for at least three years while maintaining a decent percentage of germination. And even a group of very old seeds may have 10 or 20 percent that still sprouts.
What is the oldest heirloom seed?
A very old heirloom is the 1500 Year Old Cave Bean found in a sealed clay pot in a cave in New Mexico, U.S.A. Thought to be left by the Anasazi Indians, this bean seed still germinated after all that time. The majority of heirloom seeds are open- pollinated, meaning that they reproduce themselves from seed.

What's the oldest plant ever?

Will 20 year old seeds germinate?
Yes! Even seeds that are thousands of years old can germinate. But proper pre-treatment is essential, and the older the seed, the less energy it has left in storage. Seeds from annual plants aren't often designed to last many years, part of what makes the germination process so tricky.
Why do old seeds not germinate?
Too much or too little water is the most likely reason for seeds not germinating. With too little or no water, seeds remain dormant. With too much water, seeds become susceptible to rot or infection from soil-borne fungi (also referred to as "dampening off").
Do seeds really expire?
Most seeds last three to five years after purchase, but those dates can vary depending on the variety. Lettuce, peppers, parsnips and onions have a short lifespan and should be planted within a year or two.

What is the oldest heirloom tomato?
Now this is an heirloom tomato. Scientists searching a prehistoric lake bed in southern Argentina recently uncovered the fossilized remains of a tomato that dates back 52.2 million years.
What are the difference between old seeds and new seeds?
Seeds that are only a year old, or slightly older but whose packets are still unopened, generally germinate nicely. If they're several years old, the packs were opened and/or the seeds were stored in less than ideal conditions, subject them to a germination test.
How long can a seed survive?
Seeds in good condition and stored properly will last at least one year and, depending on the plant, may last two to five years.
What is Homogamy plant?
Homogamy is when the anthers and the stigma of a flower are being matured at the same time. The action of self-pollination guides the plant to homozygosity, causing a specific gene to be received from each of the parents leading to the possession of two exact formats of that gene.
Is a date a seed?
The date seed is a hard coated seed, usually oblong, ventrally grooved, with a small embryo. Date pits weigh 0.5 g to 4 g and represent 6 to 20% of the fruit weight depending on maturity, variety and grade (Ecocrop, 2011; Daghir, 2008; Zaid et al., 2002; Barreveld, 1993; Göhl, 1982).

Why are squirrel seeds damaged?
The mature seeds had been damaged—perhaps by the squirrel itself, to prevent them from germinating in the burrow. But some of the immature seeds retained viable plant material. The team extracted that tissue from the frozen seeds, placed it in vials, and successfully germinated the plants, according to a new study.

The ancient heirloom seeds are a crucial key to ancestral life and the evolution of the planet’s flora.
Why are seeds important?
They are also remarkably stoic, with ancient seeds found and grown in recent years. Many of these seeds from the past are tens of thousands of years old. The ancient heirloom seeds are a crucial key to ancestral life and the evolution of the planet’s flora.
Where were the seeds of the Silene stenophylla found?
Scientists in Siberia discovered a cache of seeds from the plant Silene stenophylla, a close relation of modern narrow-leafed campion. Much to their amazement, they were able to extract viable plant material from the damaged seeds. Eventually these germinated and grew to fully mature plants. Each plant had slightly different flowers but otherwise the same form. They even produced seed. It is thought the deep permafrost helped preserve the genetic material. The seeds were discovered in a squirrel burrow that was 124 feet (38 m.) below ground level.
Where were the first date palms planted?
The first successful planting of an unearthed seed was in 2005. The seeds were found in the remains of the Masada, an old building located in Israel. An initial plant was germinated and grown from the ancient date seeds. It was named Methuselah. It thrived, eventually producing offsets and having its pollen taken to fertilize modern female date palms. Several years later, 6 more seeds were germinated which resulted in 5 healthy plants. Each seed hailed from the time the Dead Sea Scrolls were under creation.
What would happen if we studied seeds?
Studying these seeds further could lead to new preservation techniques and plant adaptations that could be transferred to modern crops. Such discoveries could make our food crops more secure and better able to survive.

How long do seeds stay dormant?
Other seeds must have a period of stratification (cold). Some may lay dormant for years, others may be less viable a few months after they are mature. Some require a lot of water, others will rot if they get just a little too much moisture. And on and on, across a ton of different variables.
Why are seeds stored in seed vaults?
That was an unplanned resurrection of an extinct species, but scientists are now storing thousands of seeds in seed vaults around the world in case there are more extinctions of important plants, such as in the case of a huge asteroid strike, or a disease deadly to the plant, or even climate change.

What temperature do you need to grow lettuce?
Lettuce likes it a bit cooler, maybe 15–20 C ideally. Peppers like it hotter, around 30 C.
Can you plant seeds in the ground if they are stretched?
Once the seeds germinate, though, immediately give them direct sunlight! The seedlings grow so fast that depriving them of strong light for only a day or two will cause them to stretch. If given enough sun, even stretched seedlings can recover, but do plant them lower in the ground. If they have not received sun for several days, I’d start a new crop.
Can tomatoes germinate in darkness?
Tomatoes can germinate in either light or darkness. When starting seeds, read the catalog or the seed packet for information specific to that particular variety. Many plants require either light or dark conditions in order to break dormancy.
