Of the 25 compounds screened, ten (each at only one concentration) were employed in nine different combinations for nonsterile in vitro cultures of Cattleya aurantiaca seedlings: Amphotericin B, 10 ppm; Benlate, 50 ppm; Dowicide, 5 ppm; Ethirimol, 50 ppm; Gentamicin, 50 ppm; Nystatin, 25 ppm; PCNB, 100 ppm; Penicillin G, 100 ppm; Sodium omadine, 5 ppm; and Vancomycin, 50 ppm. All nine combinations prevented contamination, but had different effects on seedling development. Citing Literature Volume66, Issue7August 1979Pages 825-835 RelatedInformation
