Natural and induced polyploidy in Acacia dealbata Link. and Acacia mangium Willd.
Seeds were obtained from seven natural populations of Acacia dealbata, three natural populations of A. mangium and a seed orchard of A. mangium, representing the natural range of the two species. Polyploids were discovered in two of the seven populations of A. dealbata. The 2C DNA amount for diploid A. dealbata (2n = 2x = 26) was 1.74 pg, and for diploid A. mangium (2n = 2x = 26) was 1.30 pg. A...
متن کاملDirect Organogenesis and Plant Regeneration from Cotyledons of a Multipurpose Tree, Acacia mangium Willd
Using cotyledons of 2-week old in vitro germinated seedlings, a rapid and efficient regeneration protocol was established for A. mangium on Murashige and Skoog (MS) basal medium. Cotyledons showed better direct shoot organogenesis producing maximum 10.88 ± 0.35 shoots per explant when cultured on MS medium supplemented with 2.0 μM BA and 1.0 μM NAA. Full strength of MS medium supplemented with ...
متن کاملPhenolic extracts from Acacia mangium bark and their antioxidant activities.
Phenolic compounds are present at very high concentrations in the bark of Acacia mangium. These compounds are known to have strong antioxidant activity and thus different beneficial effects on human health. Phenolic compounds in bark of A. mangium were extracted and their antioxidant activities were investigated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging and ferric-r...
متن کاملSESSION TWO ORAL PRESENTATION C Effect of Charcoal Application to Early Growth Stage of Acacia mangium
Charcoal is one of the important energy sources in the developing countries. Additionally, it is effective not only in carbon fixation and inactivation in the atmosphere but also in environmental conservation when used as an agent such a soil conditioner or growth accelerator of plants. However the utilization of charcoal in forestry sector, especially industrial plantation, has not been introd...
متن کاملThe Determination of Cellulose Spiral Angle by Small-Angle X-Ray Scattering from Structurally Characterized Acacia mangium Cell Wall
The spiral angle of the elementary cellulose fibril in the wood cell wall, often called microfibril angle, (MFA). Microfibril angle in hardwood is one of the key determinants of solid timber performance due to its strong influence on the stiffness, strength, shrinkage, swelling, thermal-dynamics mechanical properties and dimensional stability of wood. Variation of MFA (degree) in the S2 layer o...
