    [林业前沿资讯]
    
    •   The estimation of forest residual biomass is of interest to assess the availability of green energy resources. This study relates the Pinus halepensis Miller forest residual biomass (FRB), estimated in 192 field plots, to several independent variables extracted from Airborne Laser Scanner (ALS) data in Aragon region (Spain). Five selection approaches and four non-para...

    •   Populus is an important economical woody species due to its fast growth. In vitro induction of hexaploidy and investigation of morphological and anatomical characteristics in ((Populus alba?×?P. glandulosa)?×?P. tomentosa) were conducted in this study. Chromosome doubling was induced in vitro in a triploid clone ((Populus alba?×?P. glandulosa)?×?P. tomentosa) with ory...

    •   Bacterial colonization and biofilm formation on indwelling medical devices potentially cause serious and life-threatening infections. Technologies to prevent bacterial colonization and biofilm formation on biomedical devices are in great demand. Here, we report the preparation of coating monomers by conjugating rosin acid-derived maleopimaric acid quaternary ammonium ...

    [林业前沿资讯]
    
    •   Background: Aspartic protease (AP) is one of four large proteolytic enzyme families that are involved in plant growth and development. Little is known about the AP gene family in tree species, although it has been characterized in Arabidopsis, rice and grape. The AP genes that are involved in tree wood formation remain to be determined.
      Results: A total of 67 AP g...

    •   BackgroundSeed germination, a complex, physiological–morphogenetic process, is a critical stage in the life cycle of plants. Biological changes in germinating seeds have not been investigated in poplar, a model woody plant.ResultsIn this study, we exploited next-generation sequencing and metabolomics analysis and uncovered a series of significantly different genes and...

    6 Plant Oil-Based Supramolecular Polymer Networks and Composites for Debonding-on-Demand Adhesives

    •   The stimuli responsiveness of supramolecular polymers has recently been exploited for the development of adhesives that can be (de)bonded on demand when heated or exposed to UV light. However, it remains difficult to combine competitive solid-state mechanical properties and very low melt viscosity in one material. Here we report a new supramolecular polymer adhesives ...

    7 Regulating tannic acid-crosslinked epoxidized soybean oil oligomers for strengthening and toughening bamboo fibers-reinforced poly(lactic acid) biocomposites

    •   Bamboo fibers-reinforced poly(lactic acid) (BF/PLA) biocomposites were strengthened and toughened with tannic acid-crosslinked epoxidized soybean oil (TA-ESO) oligomer via reactive extrusion. By adjusting the concentration of TA-ESO on the BFs surface, TA-ESO oligomer was designed to localize at the interface of the composites and then to disperse within PLA matrix. A...

    •   Research Highlights: Tree decline can alter soil carbon cycling, given the close relationship between primary production and the activity of roots and soil microbes. Background and Objectives: We studied how tree decline associated to old age and accelerated by land-use change and increased drought in the last decades, affects soil properties and soil respiration (Rs)...

    9 Photosynthetic heat tolerance of shade and sun leaves of three tropical tree species

    [林业前沿资讯]
    
    •   Previous studies of heat tolerance of tropical trees have focused on canopy leaves exposed to full sunlight and high temperatures. However, in lowland tropical forests with leaf area indices of 5–6, the vast majority of leaves experience varying degrees of shade and a reduced heat load compared to sun leaves. Here we tested whether heat tolerance is lower in shade tha...

    10 Assessing the performance of indicators resulting from three-component Freeman-Durden polarimetric SAR interferometry decomposition at P-and L-band in estimating tropical forest aboveground biomass

    •   Aboveground Biomass (AGB) estimation performance in a dense tropical forest using Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) data, at P-and L-band, is evaluated. At high levels of biomass, the backscatter saturation effect leads to a low sensitivity of the backscattered intensity for biomass. This study tries to overcome this problem based on dec...
