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

Shade level recommendation for

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

of Anthurium andraeanumof Anthurium andraeanum

Constructed bed Planted bedsConcaved bottom

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.
