Lentinus edodes
(Berk.), the shiitake mushroom, is worldwide one of the most
widely cultivated mushrooms. Sawdust is the most popular
basal ingredient used in synthetic substrate formulations
for producing shiitake spawn. However, the best sawdust for
this uses needs to be determined. Shiitake mushroom was
cultivated on sawdust from the woody plants Babla (Acacia
nilotica L.), Champa (Michelia champaca L.),
Garzon (Dipterocarpus alatus
Roxb.),
Ipil-ipil
[Leucaena glauca (Linn) Benth], Jackfruit (Artocarpus
heterophyllus
Lam),
Mango (Mangifera indica L.), Raintree [Albizia
saman (Jacq.) F Müll],
Segun (Tectona grandis L.), Shimul (Bombax ceiba
L), Shisoo (Dalbergia
sissoo
Roxb)
or mixtures of sawdust from
all
of the trees with equal ratio or rice straw to determine
growth and fruiting characteristics. Cultivation on
Jackfruit resulted in significantly faster mycelial growth
compared to other substrates. With respect to
fructification, culture on Jackfruit produced the first
pinhead (primordium) earlier compared to other substrates.
Numbers of primordial and effective fruiting bodies was
highest on Jackfruit sawdust. Rice straw, surprisingly, did
not produce any fruiting bodies as well as showing no yield
attributes. Yield attributes including stalk length, stalk
diameter and diameter and thickness of the pileus were
significantly higher on Jackfruit. The lowest biological and
economic yields were found when culture was on Champa.
Biological efficiency and biological yield, economic yield
and dry yield at the first and final harvests were highest
with culture on Jackfruit and its use is recommended in the
production of shiitake mushroom in the tropics.
