ABSTRACT Calcium and boron are important nutrients in the stages of flowering, pollen germination fruiting process. As these poorly mobile plant, some authors recommend foliar spraying production seeds species. The objective was to study influence calcium boron, via application directed inflorescences, production, quality accumulation lettuce seeds. Four treatments were evaluated (only calcium:...

Variation in water quality can directly affect the composition of benthic assemblages on coral reefs. Yet, few studies have quantified nutrient and suspended particulate matter (SPM) to examine their potential impacts community structure, especially around high oceanic islands. We assessed spatio-temporal variation nutrients SPM across six sites American Samoa over a 12-month period used explor...

UNLABELLED Single-celled organisms have different strategies to sense and utilize nutrients in their ever-changing environments. The opportunistic fungal pathogen Candida albicans is a common member of the human microbiota, especially that of the gastrointestinal (GI) tract. An important question concerns how C. albicans gained a competitive advantage over other microbes to become a successful ...

anthropogenic eutrophication conditioned frequent and more pronounced blooms of toxicalgae and cyanobacteria in the fresh and saline aquatic ecosystems all world around. however, bloomingspecies could serve as a possible resource instead of a threat by exploiting them to remediate nutrients. theoptimised use of algae and cyanobacteria may provide the environmental service together with economic...

The impact of different concentration of zinc (Zn) and boron (B) on growth and mineral composition of lemon seedlings (Citrus Aurantifolia L.) was studied under greenhouse conditions. We used five concentration levels of B (0, 2.5, 5, 10 and 20 μg g-1 soil) and three of Zn (0, 5 and 10 μg g-1 soil). Fresh and dry plant weights of the control treatment were strongly decreased with B levels highe...

Background An economical strategy for producing microalgae as biofuel feedstock is driven by the freshwater and nutrients input. In this study, seawater was applied to limnetic algal cultivation and the behavior of algae in seawater media was observed including growth, lipid synthesis, and ultrastructure. To make seawater cater algae, a kind of wastewater, anaerobically digested effluent from k...

Cadmium (Cd) is a highly toxic heavy metal for both plants and animals. The presence of Cd in agricultural soils is of great concern regarding its entry into the food chain. Cadmium enters into the soil-plant environment mainly through anthropogenic activities. Compounds of Cd are more soluble than other heavy metals, so it is more available and readily taken up by plants and accumulates in dif...

Osteoporosis is a condition of the bone mass declination along with deterioration of bone microarchitecture, which can be found in both women and men. Its prevalence increases with advanced age. Osteoporosis cannot be permanently cured. The best current treatment only slows down the bone deterioration. Prevention of osteoporosis and promotion of bone mass and quality must be paid attention to f...

Developing seeds constitute a strong sink for the plant and rely on the turnover and mobilization of carbon and nitrogen assimilates to supply the nutrients needed for their maturation. In large part these nutrients emanate from the vegetative organs including leaves and pod walls. Vegetative lipoxygenases (VLXs) accumulate in the paraveinal mesophyll cell layer of soybean (Glycine max L.) leav...

As a part of the USEPA's concentrated animal feeding operation (CAFO) final rule, all CAFOs are required to develop and implement a nutrient management plan (NMP). The USEPA's emphasis on better management of nutrients appropriately targets a critical environmental issue associated with animal production. The concentration of animals in livestock feeding operations, often separate from feed gra...
