Application of IAA and IBA as a plant growth regulator in the seed bed of cardamomThe research was intended to find out the effect of IAA and IBA (indole acetic acid and indole butyric acid) plant growth regulators in the seed bed of cardamom. It was implemented in the research Institute of Spices and Medicinal Crops, Bogor, in January up to April 1986. A randomized block design was applied with seven treatment i.e. control, IAA plat growth regulator with the concentration of 25, 50, 100 ppm, and IBA plant growth regulator with the concentration of 50, 100, and 150 ppm with three replications. The order kost Research result revealed that applying both plant growth regulators with those concentrations did not stimulate the growth of cardamom in the seed bed. It tended, however, to heighten the seedings, the amount of leaves and the weight of roots. Higher concentration of those plant growth regulators tended to retard the seed growth.
