Isolation and Fractionation of Hemicelluloses from Salix Psammophila
Waterand alkali-soluble hemicelluloses were isolated with hot water and 10% KOH at 25 °C from dewaxed and delignified Salix psammophila, respectively. The alkali-soluble hemicelluloses were then successively subfractionated by neutralization and subjected to gradual precipitation in the end, using ethanol concentrations of 15, 30, 45, 60, 75 and 90%, respectively. Chemical composition, physico-...
متن کاملSelection of Reliable Reference Genes for Gene Expression Analysis under Abiotic Stresses in the Desert Biomass Willow, Salix psammophila
Salix psammophila is a desert shrub willow that has extraordinary adaptation to abiotic stresses and plays an important role in maintaining local ecosystems. Moreover, S. psammophila is regarded as a promising biomass feedstock because of its high biomass yields and short rotation coppice cycle. However, few suitable reference genes (RGs) for quantitative real-time polymerase chain reaction (qR...
متن کاملDe novo transcriptome assembly, development of EST-SSR markers and population genetic analyses for the desert biomass willow, Salix psammophila
Salix psammophila, a sandy shrub known as desert willow, is regarded as a potential biomass feedstock and plays an important role in maintaining local ecosystems. However, a lack of genomic data and efficient molecular markers limit the study of its population evolution and genetic breeding. In this study, chromosome counts, flow cytometry and SSR analyses indicated that S. psammophila is tetra...
متن کاملA model of Barchan dunes including lateral shear stress.
Barchan dunes are found where sand availability is low and wind direction quite constant. The two dimensional shear stress of the wind field and the sand movement by saltation and avalanches over a barchan dune are simulated. The model with one dimensional shear stress is extended including surface diffusion and lateral shear stress. The resulting final shape is compared to the results of the m...
متن کاملBehavior and identification of ephemeral sand dunes at the backshore zone using video images.
The backshore zone is transitional environment strongly affected by ocean, air and sand movements. On dissipative beaches, the formation of ephemeral dunes over the backshore zone plays significant contribution in the beach morphodynamics and sediment budget. The aim of this work is to describe a novel method to identify ephemeral dunes in the backshore region and to discuss their morphodynamic...
