Micropropagation of Kolikuttu & Grapes var. Thompson
Seedless & Sonaka
• Multiplication rate of kolikuttu is very low under invitro
conditions(less than 200)
• Difficult to produce more plants of these seedless grape
varieties with the conventional propagation methods.
Tissue Culture
one year period -500 plantlets of Kolikuttu
Six months 250 plantlets of grapes could be produced with
developed protocol.

Paddy Straw Mushroom ( Volvariella volvacea )
Indoor cultivation method was developed to
maintain the environmental factors suitable for
straw mushroom
Low cost spawn production for oyster mushroom (
Pluerotus ostreatus) was developed using locally
available saw dust
Rubber saw dust can be used for spawn production with
low cost.
Cultivation of Ganoderma lucidum
Ganoderma (Reishi) mushroom can be successfully
cultivated using local available raw materials in Sri Lanka.
However, further experiments should be carried out
to develop a cultivation package.
Cultivation of oyster mushroom using straw
Paddy straw is one of the most suitable alternative
material for Oyster mushroom cultivation.
Cultivation of king oyster mushroom
(Pleurotus erryngi) using locally available raw
materials

Anthurium andraeanum
85 %
70%
18,000 – 25,000 Lux of maximum light intensity (LI) or
80 – 85 % shade level for open lands could be
recommended for Anthurium andraeanum in the
intermediate zone
Development of drainage improved low cost
bed structure
Raised bed of 1.2 m width and 50 cm height constructed with
four vertical faces which fixed using 60 cm corrugated asbestos
sheet pieces. Concaved bottom of the bed was sloped towards
the edges to drain out of excess water through holes at the base
of vertical sides could be recommended for intensive cultivation

Development of low cost shade house for
Anthurium andraeanum
� Shade house has been
constructed utilizing gliricidia
canopy and shade netcombined
with bamboo frame excluding
hardware.
� Celcure CB-90 preservation can also
be applied to improve durability of a
bamboo frame under field condition.
� In this method, Vacuum Pressure
Impregnation is done with
compounds of copper, chrome and
boron salts (CCB) in a composition
which is water borne preservative
Fractionation effect of the total nitrogen supply
on Anthurium
N fertilizer having N-NH4+ and N-NO3
- at a ratio of 2:1 or 1:2 was more
effective in total nitrogen supply in flower production in anthurium than
N fertilizer having sole ammonium sulphate or calcium nitrate.
