The study aimed to determine the anthocyanin content in callus cultures of Sesbania grandiflora L. (Red Katuray) using petal explants as influenced by 2,4-D and BA. The specific objective of this study is to determine the effect of plant growth regulators specifically auxin (2,4-D) and BA (Benzyladenine) on Murashige and Skoog’s (MS) medium in anthocyanin production. Earliest callus initiation was noted in 2.5 ppm to 5.0 ppm 2,4-D without BA and 2.5 ppm 2,4-D with 2.5 ppm BA. Same treatment combination had the highest degree of callus formation and obtained the greatest percentage of callus formation 2.5 ppm 2,4-D without BA and 2.5 ppm 2,4-D with 2.5 ppm BA. The heaviest weight of callus was registered at 2.5 ppm 2,4-D without BA. Significantly higher anthocyanin content was noted in 2.5 ppm to 5.0 ppm 2,4-D without or with 2.5 ppm BA, with 2.5 and 5.0 ppm BA and with 5.0 ppm 2,4-D and 2.5 ppm BA. There is a positive relationship between callus formation and anthocyanin production. Results showed that treatments that promoted significantly greater callus formation e.g. 2.5 ppm 2,4-D alone or in combination with 2.5 ppm BA also produced the highest anthocyanin content.
