15 16 Here we investigate relationships between NDVI, Biomass, and Leaf Area Index (LAI) for 17 six key plant species near Barrow, Alaska. We explore how key plant species differ in 18 biomass, leaf area index (LAI) and how can v e g e t a t i o n spectral indices be used to 19 estimate biomass and LAI for key plant species. A vegetation index (VI) or a spectral 20 vegetation index (SVI) is a q...

Background Global warming, environmental disasters, and increasing oil prices have catalyzed a worldwide trend to use plant biomass as a renewable source for liquid biofuels and bio-based materials. Plant biomass can be processed into fermentable sugars by enzymatic depolymerization of the cell wall polysaccharides, followed by fermentation. However, the presence of lignin in the cell wall cons...

Although maize (Zea mays L.) routinely experiences both intraand interspecific competition for limited resources, most plant-plant interaction studies have principally focused on maize-weed interactions. Thus very few investigations have considered the impacts of plant crowding and nitrogen (N) availability on maize intra-specific competition. The primary objective of this two-year field study ...

• A high ability of alien plant species to capitalize on increases in resource availability has been suggested as an explanation for being globally successful. Here, we tested this hypothesis meta-analytically using existing data from experiments manipulating plant resources (light, water and nutrients). • From these studies we extracted the response to resource increase of biomass, as an indic...

BACKGROUND Understanding the biological mechanisms used by microorganisms for plant biomass degradation is of considerable biotechnological interest. Despite of the growing number of sequenced (meta)genomes of plant biomass-degrading microbes, there is currently no technique for the systematic determination of the genomic components of this process from these data. RESULTS We describe a compu...

The narrow genetic variation of bread wheat is one of the limitations to improve it for drought-tolerance. The research carried out to study the responses of different genotypes and traits to imposed moisture stress. The plant material comprised of 10 Aegilops tauschii accessions as well as a tolerant (BW2) and a susceptible (BW1) bread wheat cultivar. To assess the root and shoot-traits, two s...

in the present study, hydrilla verticillata biomass was investigated as a novel biosorbent for the uptake of basic dye malachite green from its aqueous solution. kinetic and equilibrium studies were carried out in batch process. batch adsorption experiments were conducted to study the effect of ph, temperature, sorbent dosage, initial dye concentration, and contact time for the removal malachit...

Soil aggregate stability data are often predicted to be positively associated with measures of plant productivity, rangeland health, and ecosystem functioning. Here we revisit the hypothesis that soil aggregate stability is positively associated with plant productivity. We measured local (plot-to-plot) variation in grassland community composition, plant (aboveground) biomass, root biomass, % wa...

Plant biomass is an important parameter for crop management and yield estimation. However, since biomass cannot be determined non-destructively, other plant parameters are used for estimations. In this study, plant height and hyperspectral data were used for barley biomass estimations with bivariate and multivariate models. During three consecutive growing seasons a terrestrial laser scanner wa...

Differing biomass allocation strategy could be a necessary plant-trait associated with invasive weeds in an alien environment. The present study focused on exploring differential biomass allocation pattern as an invasive plant-trait in the two pantropical invasive malvaceous weeds Sida acuta Burm f. and Sida cordifolia L. in an anthropic peri-urban vegetation in Indian dry tropics. Eighty plant...
