Heat requirement for breaking dormancy of oil palm seeds after storage under different conditions
1982
Mok, C.K.
The oil palm seed has to undergo a high temperature treatment for rapid and maximal germination. The heat requirement of seeds after different periods of storage under various conditions have not been defined and were, therefore, investigated. It was found that seeds kept at 20% moisture content germinated during storage. The germination was 0.2% at 20 deg Centrigrade but reached 19.6% at 20 deg Centigrade after twelve months of storage. The seeds were contaminated by fungi which apparatently had no effect on seed viability. The rate of germination of these seeds was over 93%. Twenty days heating was as effective as forty or sixty days in breaking the dormancy of stored seeds, but inadequate for fresh seeds. At low storage moisture content, seeds lost their viability and germination after eight months of storage, especially at the higher temperature of 29 deg Centigrade. Seed impaired during storage were further injured by the heat treatment. Germination of these seeds were poor. The longer the period of heat treatment, the greater was the adverse effect
