tial reduction of the total mass of the substrate.

Controlling the loss of carbon dioxide has a
beneficial impact on overall yield. Zadrazil
(1976) showed that fully 50% of the mass of
wheat straw evolves into gaseous carbon diox-

production. (See Figure 39.)
Another factor in choosing a type of column
culture is greatly determined by the mushroom
strain. Strains of Oyster mushrooms which produce clusters of many mushrooms, and which
are site-specific to the perforations, work better in the perforated column model than in the
fully exposed one. Mushroom strains which
produce only one, two or three mushrooms per
cluster—as with some Pleurotus pulmonarius
cultures—do not demonstrate an obvious advantage with the perforated column method.
Hence, the benefits of perforated column can be
easily overlooked unless you test many Oyster

off the ground.

ethylene tubing has yet to be surpassed.
Some growers strip the columns after colonization to expose the greatest surface area.The
columns are held together with two to four vertically running lengths of twine. Although the
intention is to maximize yield, the massive loss
of moisture, combined with the die-back of exposed mycelium, can cancel any advantage
contemplated. El-Kattan (1991) and others who
have conducted extensive studies have found

the accumulation of carbon dioxide during
colonization has an enhancing effect on subse-

quent yields. Studies prove the partially
perforated plastic gives rise to larger fruitings
of Oyster mushrooms sooner than substrates
fully exposed. Exposed columns not only lose
more moisture, but they also allow the sudden
escape of carbon dioxide, resulting in a substan-

is added and the plastic elongates.
