. Winarto, B. 2007. Response of Axillary and Adventitious Shoot Formation of In Vitro Anthurium Culture. Planting material propagation is one of important problems in anthurium cultivation for commercial purposes. Conventionally, the plant is generally propagated by seed and shoot, however those technique were time consuming. The objective of this experiment was to know response of axillary and adventitious shoot formation of in vitro anthurium culture. The experiment was conducted at Tissue Culture Laboratory, Indonesian Ornamental Crops Research Institute from July 2004 to February 2005. Variation of explant such as first and second node was used for induction of axillary shoot formation, while young root, hypocotyl, and leaf were used for stimulating adventitious shoot regeneration. The explants harvested from several cultivars and accessions of anthurium. Media of M2, M4, and modified-M4 using150 ml/l coconut water, 2.5 mg/l 2,4-D, 2 g/l pantothenic acid, and 50 ppm cefotaxim were used in this experiment. Results of the study indicated that the success of anthurium tissue culture was affected by cultivars, explant type and condition, and growth medium. Each explant and cultivar had its compatibility to different growth media. Adventitious shoot formation was potential and suitable technique to be developed than axillary shoot proliferation. M4 was the appropriate and suitable basic medium that could be developed for in vitro propagation of anthurium. Results of this research could be expected as one of important consideration points in developing and applying tissue culture technique on anthurium propagation.
