Direct 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 کاملNatural 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 کاملEcological Impact on Nitrogen and Phosphorus Cycling of a Widespread Fast-growing Leguminous Tropical Forest Plantation Tree Species, Acacia mangium
Symbiotic nitrogen fixation is one of the major pathways of N input to forest ecosystems, enriching N availability, particularly in lowland tropics. Recently there is growing concern regarding the wide areas of fast-growing leguminous plantations that could alter global N2O emissions. Here, we highlight substantially different N and phosphorus utilization and cycling at a plantation of Acacia m...
متن کاملClonal Propagation of Acacia koa
Introduction Koa (Acacia koa) is currently the most important commercialized hardwood in Hawai'r's forests. A sustainable supply of koa will depend on reforestation with the best adapted seed sources and perhaps with vegetatively propagated cultivars having unique traits. At present, koa forests are in a serious state of decline, and improvement appears warranted if sustainable supply is to be ...
متن کاملEffective in vitro seed germination and direct regeneration from cotyledonary leaf explants of Nitraria schoberi
Nitraria schoberi (Ghar-e-Daghin in Persian) from Zygophyllaceae (Nitrariaceae) family is considered as a wonderful exquisite plant in terms of its economical, medicinal, animal feed, significant values and also its unique characteristics of being tolerant to the soil salinity, drought and erosion. On the other hand, this plant is challenging with severe problems such as seed dormancy, plant gr...
