A Medium: Appearance: White crystal or powder Molecular Formula: C10H13N5O Molecular Weight: 219.24 Plant cell culture tested Cytokinin growth regulator. Mixed isomers, 90% trans isomer. Balance primarily cis isomer. Application Zeatin is a coconut milk-derived plant hormone (cytokinin) that promotes growth of lateral buds, stimulates cell division (Lateral Dominance), callus initiation and seed germination. Zeatin is used with Murashige and Skoog and otheA Medium Broth is a minimal medium, on which bacteria can grow rapidly if it contains a carbon compound such as glucose, which serves as both a carbon source and an energy source. Salts are also present to supply nitrogen, phosphorus, and trace metals the E. coli would need during its growth cycle 1. A Medium Broth requires that 10 ml of a 20% solution of glycerol and 1 ml of 1M MgSO4 be added after autoclaving. The magnesium sulfate supplies the necessary magnesium ions that are required for DNA replication.r media, zeatin promotes multiple shoot generation from internodes and high frequency thick spread roots.
