Abstract

The fruit of Dabai (Canarium odontophyllum Miq.) is one of the Sarawak indigenous fruit that has potential for commercialization. Therefore, there is a need for more planting material for planting it beyond its present localities. Two approaches of propagation were attempted namely conventional propagation through bud-grafting and micropropagation by means of surface sterilization to the explants. For bud-grafting, scion derived from hardwood was found having higher success. Pruning off top growth of the rootstock and growing grafted plant in area exposed to sunlight was found to increase bud break in Dabai. Whilst, in the micropropagation method, the medium for Dabai explants was found to be favourable under the use of solid agar. A higher potential of success could be achieved when the shoot tips are used as explants. However, the different PPM™ treatments in surface sterilization experiments were found to have no significant difference in producing axenic explant.
