Spawn or mushroom seed is referred to as a dense mass of white mycelium obtained from pure cultivation, which after producing a plate containing pure mushroom seed filament culture is transferred to a glass (stock) containing wheat or rye seeds , and after the stock turns white, each stock becomes about 30 kg of mushroom seeds .
The mushroom seeds insidepolypropylene bags areheat-resistant, and the substrate for the cultivation of rice is wheat in Iran, but rye in Europe.
Since mushroom seed production requires laboratory and microbiological technical knowledge.
Mushroom seed laboratory devices
Laboratory devices such as autoclave, laminar air flow are necessary for the production of mushroom seeds . Unlike button mushroom growers , there are only a handful of quality button mushroom seed producers in Iran.
Characteristics of high-quality button mushroom seeds :
Mushroom seeds are completely white and grainy
No texture or thread aggregation on the wheat grain
No sour smell
No colored powder piles
Note: The smell of sourness indicates bacterial attack and powdery spots indicating mold in mushroom seeds . These spots are seen in white, black, and orange colors.
Several types of button mushrooms that are industrial in Iran or more marketable are produced in this unit, which include A15, 512,737, 2100, 2200, Magnum and Delta breeds.
Button mushroom seeds are supplied in two ways:
1. in poly bags weighing 1 kg with cotton caps
2. in bags with HEPA filter weighing 1-10 kg
Delivery of mushroom compost in 1 to 7 days
