Abstract

In vitro cultures of the medicinal herb, Aerva lanata exhibited heterogeneity in diverse concentrations of (0.5-10 mg/l) silver nitrate. The texture of the callus tissue varied from friable, non-friable to nodular. Callus cultures also exhibited a color variation ranging from white, brown to black. Silver nitrate did not exhibit a significant variation in the accumulation of in vitro biomass at a concentration range of 0-5 mg/l. Higher concentrations were found inhibitory for callus growth. The cultures exhibited a positive correlation between silver nitrate concentration and accumulation of phenolics as well as flavonoids up to a concentration of 5.0 mg/l. The results generated clearly indicated that silver nitrate may be used as an additive for regulating the callus morphology, growth and accumulation of phenolic compounds under in vitro conditions.
