Abstract: The effect of interaction among exogenous hormones auxin (IBA), Gibberellins Acid (GA3) and cytokinin (6-BA), photoperiod and cultivars on the total dry matter of strawberry plant was investigated in Cameron Highland, Pahang, Malaysia. The five factorials experiment with three replications was designed in a split plot factorial Randomized Completed Block Design (RCBD). A total of 864 plants involve and were placed under 400 m2 plastic rain-shelter. Two Malaysian commercial strawberry cultivars, Camarosa and Camaroga, were used. The plants were exposed to three photoperiod levels (12 (normal day length of Cameron Highland), 15 and 18 h) and sprayed with 0 and 50 ppm IBA, GA3 and 6-BA. The results showed that only GA3 gave the significant effect on the dry matter of strawberry by its own action where, 17.06% dry matter content was produced under application of 50 ppm GA3. The result demonstrated that the photoperiod, variety, IBA and 6-BA factors do not act individually on the production of strawberry dry matter but rather by the mutual interaction among them. It was found that the highest, 21.2%, dry matter content of the strawberry was produced by Camaroga cultivar grown under 15 h photoperiod and treated with 50 ppm IBA and GA3 and thus such combined treatment is recommended as the best condition for increasing productivity of strawberry in Cameron Highland.
