In Vitro Plant Regeneration, Antioxidant And Antibacterial Studies On Broccoli, Brassica Oleracea Var. Italica, Rosna Binti Mat Taha
In Vitro Plant Regeneration, Antioxidant And Antibacterial Studies On Broccoli, Brassica Oleracea Var. Italica, Rosna Binti Mat Taha
Rosna Binti Mat Taha
Leaf and shoot tip explant of Brassica oleracea var. italica were inoculated on Murashige and Skoog (MS) basal medium supplemented with various concentrations of (BAP) and (IBA), alone and in combinations to achieve plant regeneration. Subsequently, antioxidant and antibacterial activities were determined from In vitro and In vivo plant parts. The highest mean numbers of shoot was observed on combinations of 1 mg l(-1) and 1.5 mg l(-1) of BAP and IBA, 9.49 and 8.69, respectively. The highest number of shoot produced (11.55) per shoot tip explant was recorded on 2.5 mg l(-1) BAP. In addition, highest percentage of roots …
Total Phenolic Contents, Antioxidant And Antimicrobial Activities Of Bruguiera Gymnorrhiza, Rosna Binti Mat Taha
Total Phenolic Contents, Antioxidant And Antimicrobial Activities Of Bruguiera Gymnorrhiza, Rosna Binti Mat Taha
Rosna Binti Mat Taha
In the present work, the antioxidant and antibacterial activities of methanolic, ethanolic and chloroform crude extract of leaves and barks of Bruguiera gymnorrhiza were investigated. The antioxidant activity of the crude extracts were evaluated using the enzymatic and non enzymatic methods namely superoxide dismutase determination, reducing power assay and 2, 2-diphenyl-1-picrylhydrazil free radical scavenging assays. Folin-ciocalteu reagent method was used to estimate the amount of total phenolic compounds of the extracts. Ethanol extract of barks showed the best result in all antioxidant assays which was positively co-related with the total phenolic contents. There was no significant difference between the IC(50) …
Effect Of Picloram, Additives And Plant Growth Regulators On Somatic Embryogenesis Of Phyla Nodiflora (L.) Greene, Rosna Binti Mat Taha
Effect Of Picloram, Additives And Plant Growth Regulators On Somatic Embryogenesis Of Phyla Nodiflora (L.) Greene, Rosna Binti Mat Taha
Rosna Binti Mat Taha
The present study describes the plant regeneration via somatic embryogenesis in suspension culture derived from the leaf and stem explants of Phyla nodiflora. The medium type, plant growth regulators, complex extract (coconut milk and malt extract) and anti-oxidant (activated charcoal, ascorbic acid, Polyvinylpyrrolidone and citric acid) markedly influenced the embryo regeneration of P. nodiflora. MS with 2,4-D and activated charcoal (10 mg/L) gave the highest stimulation of embryogenic callus growth. Optimized callus was transfered into suspension culture, which showed the globular, heart shaped embryos in MS with 2,4-D + BA + picloram (0.1 mg/L), coconut milk (10 ml/L), citric acid …
