Do pistachio seeds have an expiration date?

Important factors in pistachio seed germination

There are several important factors that can affect pistachio seed germination, including:

Humidity:

The seed bed should always be moist enough for the pistachio seed to germinate after absorbing water, the seeds germinate at a humidity of 50% moisture by weight (relative to the dry weight of the seed).

Heat:

The most suitable temperature for the germination of Iranian Pistachio seeds is between 18-25 degrees Celsius. Cold-loving plants usually germinate at lower temperatures than heat-loving plants. The lower the temperature of the seed bed than the optimal germination temperature, the lower the percentage of seed germination and seedling growth will be.

Oxygen:

When the environmental conditions are suitable in terms of humidity and temperature, seed germination begins. In this case, seed germination begins with the metabolism of its stored materials. This process requires oxygen. When planting pistachio seeds, if they are planted in a deep place or in an environment saturated with water, they will not germinate due to not receiving oxygen.

the light :

Light accelerates germination, and the more light reaches the germinated seed, the faster it grows.

According to the mentioned issues, do the seeds have an expiration date?

In fact, the seeds have an expiration date, but they can maintain their nominal potency for years under the right conditions.
These conditions depend on several factors.
- The most important of which is the environmental conditions of seed storage.
- The absence of moisture, heat and light is one of the most important conditions for optimal storage of seeds.
- The lower the humidity, heat and light of the environment, the longer the seeds can maintain their nominal strength.
If the above three factors are not observed, it can even make one-day-old seeds non-germinating
Purgatory seed storage
You may be interested to know that in February 2008 in Svalbard, Norway, a warehouse with the above conditions was opened, where hundreds of thousands of varieties of agricultural seeds are kept.
This large warehouse was dug on a remote island in the Svalbard archipelago, 100 kilometers from the North Pole, at the end of an ice tunnel 410 feet deep into the ground.
This warehouse is known as the Doomsday seed treasury warehouse.
In this warehouse, even if the electricity supply is cut off and the storage devices are not working, the environmental conditions are such that enough cold is maintained for the survival of agricultural seeds for up to 1700 years.
And it is even predicted that if the earth warms for two hundred years, ice will naturally exist around this treasure and the seeds will still remain healthy.
So far, 430,000 types of seeds from all over the world have been collected in this treasury, and this collection is still ongoing.

One of the economic ways to buy large quantities of pistachios is to buy pistachio wholesale from Taher Nuts and Dry Nuts Group. This method of shopping is very smart and affordable.
