Using Thermal Units to Predict Biomass Accumulation and Total Nitrogen Uptake for Cover Crops in Arkansas
… GDD parameters could improve the estimation of biomass production of cover crops. Generally, GDD is the summation of daily thermal units [DTU], and DTU can be calculated using several different methods, but all use species-specific cardinal temperatures. There are very basic equations to …

Bioenergetics and metabolism of eukaryotic cell proliferation
… transformation of cell-external nutrients into biomass. Strategies of biomass accumulation across the kingdoms of life are diverse and range from carbon fixation by autotrophic organisms to direct biomass incorporation of consumed nutrients by heterotrophic organisms. The goal of this …

Excretal architecture : prototypical and productive urban waste forms
… to grow a regenerative city, while focusing on biomass accumulation as a key program. These structures are scalable and adaptable to any site, but are designed for cities that face ramifications of the industrial eras in particular - mainly toxic contamination in water and soil. The main purpose …

Stream aufwuchs accumulation
I investigated the Aufwuchs accumulation process on glass slides (chlorophyll, adenosine triphosphate, and diatoms) in experimental streams near Glen Lyn VA (Phase I) and in Stroubles Creek near Blacksburg VA (Phase II). Depopulation experiments carried out during Phase I supported my hypothesis …

IMPROVING CANNABIS SATIVA'S PHYTOREMEDIATION CAPABILITIES OF FOREVER CHEMICALS THROUGH MICROBIAL INOCULATIONS
… resistance to degradation and potential for bioaccumulation. Phytoremediation has emerged as a potential strategy for mitigating PFAS contamination, and plant-microbe interactions may influence contaminant uptake and transport within plant systems. These studies investigated microbial …

Water-use, growth and water-use efficiency of indigenous tree species in a range of forest and woodland systems in South Africa
… they use that water more efficiently in terms of biomass accumulation, and consequently whether there is scope for the expansion of indigenous tree production systems in South Africa.

Switchgrass tolerance to cadmium: uptake and translocation
… economical source of N and other nutrients for biomass production; however, the response of switchgrass to heavy metals in the sludge is not known. Two greenhouse studies and a 2-yr field study were conducted to determine the interaction of (1) cultivar and cadmium (Cd)application, (2) soil pH …

Salt stress and UV-B radiation modulate growth, physiology and 20-hydroxyecdysone contents in Brazilian-ginseng [Pfaffia glomerata (Spreng.) Pedersen]
… with no significant effect on photosynthesis and biomass accumulation. In contrast, plants under severe salt stress (i.e., 240 to 480 mM NaCl) did not increase 20E concentrations compared to the control. Additionally, severe salt stress caused marked damage in biomass accumulation and …

Use of strigolactone for stress relief and increased productivity in high-yielding environments
… the AB-01 seed treatment had no impact on root biomass accumulation at the planting densities of 79,000 or 88,800 plant ha-1, there was significant increase in R6 root biomass accumulation in response to the AB-01 seed treatment when grown under the intensive management system that utilized a …

Controlled and protected environment production of blueberries in the Midwest United States
… in peat:perlite accumulated nearly six times the biomass of those produced in either rockwool or coir. In peat: perlite, higher VWC was directly correlated to increased biomass accumulation. High tunnel production of blueberries would have a lower economic barrier to entry than greenhouse …

Optimizing Weed Suppression Via Cover Crop and Herbicide Programs in the Mid-Atlantic
… determining if these systems lead to greater biomass accumulation, increase overall weed suppression, and reduce herbicide inputs. The goal of our first experiment was to determine if a hairy vetch (Vicia villosa R.) and cereal rye (Secale cereale L.) mixture, where the cereal rye was …

Periphyton-nutrient dynamics in a gradient-dominated freshwater marsh ecosystem.
… often resulted in an increase in periphyton biomass accumulation. However, only N alone stimulated biomass accumulation in downstream areas. Floating periphyton mats, or "metaphyton", appeared to overcome N deficiency on a seasonal basis by fixing, and efficiently retaining, large quantities …

Characterization of signaling pathways underlying key growth and development processes in Populus trichocarpa
… stress tolerance and/or improvements in overall biomass accumulation. We targeted specific tissues such as xylem, where alterations in the relationship of source and sink tissues can lead to the control of xylem cell deposition or of various wood properties. This led to the characterization of …

The role of the environmental stress response in aneuploid and cell cycle-arrested budding yeast
… mechanisms to ensure proper coordination of biomass accumulation and cell cycle progression. Cell growth can regulate cell cycle progression, and cells are required to grow to a “critical size” before entrance into the cell cycle. Much less is known about how cell cycle progression affects …

Oligohaline wetland response and recovery following storm-driven saltwater intrusion in coastal Louisiana
… sustained high water level favored belowground biomass accumulation, high shear strength, and a relatively low decomposition rate in oligohaline wetland soils in the greenhouse. In the field, plant community structure and growth following saltwater intrusion were heavily influenced by the degree …

SIMULATED MINE LAND RECLAMATION IMPACT ON BIOMASS PARTITIONING AND NUTRIENT CONTENTS IN LOBLOLLY PINE
… harvested and analyzed to determine dry biomass and nutrient (N, P, K, Ca, Mg) contents for the three treatments. Allometric equations relating dry weights of foliage, stem, branches and roots to diameter at groundline and height were developed to estimate tree biomass. Estimated biomass …

Morphological and Physiological Responses of Senegalia senegal (L.) Britton Provenances to Drought, Salinity, and Fertility
… variability of Senegalia senegal on gum yield, biomass accumulation and growth. Ngane provenance presented superior growth characteristics as both mature trees and seedlings and exhibited a more conservative water use strategy under drought. Both greenhouse studies revealed similar …

Phosphorous uptake rate in two low phosphorous updated species, Aspalathus linearis and Podalyria calyptrata
… P (4, 10, 20, 50 and lOOμM). Growth rates (biomass accumulation) were also calculated as were root to shoot ratios for both species. A. linearis had a higher uptake rate than P. calyptrata. While the fresh biomass growth rate was similar in both species, P. calyptrata had a higher dry weight …
