Effect and analysis of phenolic compounds during somatic embryogenesis induction in Feijoa sellowiana Berg

摘要: The effect of phenolic compounds on somatic embryogenesis in Feijoa sellowiana was analysed. results showed that caffeic acid (140–560 µM) significantly increased induction compared with the control. presence phloridzin, even at lower concentrations (11.5 µM), or phloroglucinol greater than 140.0 and 197.5 µM, respectively, inhibited embryo development beyond globular stage. When embryos were transferred to germination medium, highest rates (81.9%) obtained induced (79.0 µM). At all tested, medium containing germinated higher those acid. Histological ultrastructural studies formed close association phenolic-rich cells which, more advanced stages development, a zone isolating from maternal tissue. A comparative analysis total content indicated phenolics reached peak by third week culture, independently used. However, after period, amount explants cultured control acid-containing medium. Attempts identify type flavan-3-ols gallic derivatives mainly produced phloroglucinol-containing whereas flavanones dihydroflavonols also present Flavones main phenols detected ways which may affect are discussed.
