This book aims to provide a statement of current understanding of patterns of and the causes behind biodiversity. Chara vulgaris L. and Ch. canescens Lois, accumulate considerable amounts of. Root exudates improve the nutrient acquisition of plants and affect rhizosphere microbial communities. The plant nutrient status affects the composition of root exudates. The purpose of this study was to examine common bean (Phaseolus vulgaris L.) root exudates under phosphorus (P) deficiency using a metabolite profiling technique. Common bean plants were grown in a culture solution at P.
Highly calcareous (marl) lakes are infrequent but important freshwater ecosystems, protected under the EU Habitats and Species Directive. Chara lakes have been considered resistant to eutrophication owing to the self‐stabilising properties of charophyte meadows. However, the opposite is suggested by the large‐scale biodiversity declines in marl lake taxa in Europe, and evidence of. Two field experiments were conducted in Giza, Egypt during the two successive summer seasons of and to study the effect of irrigation methods, i.e. subsurface drip, surface drip, sprinkler and furrow irrigation, and potassium fertilizer levels (0, 50 and kg K2O/feddan) and their interaction on the vegetative growth, chemical.

Nadeem M, Mollier A, Morel C, Vives A, Prud'homme L, Pellerin S () Seed phosphorus remobilization is not a major limiting step for phosphorus nutrition during early growth of maize.
Willd. is 47 mg Ca l −1, for C. vulgaris L. 55 mg Ca l −1 and for Nitella mucronata A. 60 mg Ca l −1. Generally, species of the genus Chara prefer waters of higher Ca content than those of the genus Nitella (except N. mucronata). In hard water lakes, calcium cations are usually accompanied by bicarbonate anions, which are often the Cited by: The purpose of this study was to examine common bean (Phaseolus vulgaris L.) root exudates under phosphorus (P) deficiency using a metabolite profiling technique.
Common bean plants were grown in a culture solution at P concentrations of 0 (P0), 1 (P1) and 8 (P8) mg P L −1 for 1, 10 and 20 days after transplanting (DAT). Root exudates were Cited by: Although phosphorus status is not typically assessed, phosphate can be measured in both serum and plasma.
In adults, normal phosphate concentration in serum or plasma is to mg/dL ( to mmol/L). Hypophosphatemia is defined as serum phosphate concentrations lower than the low end of the normal range, whereas a concentration.
Only occasional specimens of Chara rudis A. ex v. Leonh. and C. vulgaris L. were found (Bernatowicz, ). Eight species of submerged angiosperms and one species of aquatic moss were found in the by: RESULTS AND DISCUSSION 17 The Chara found in the east branch of the Maple River was identified as Chara vulgaris L.
(Charales: Characeae), a species quite common in non-eu- trophic, temperate, lotic and lentic habitats in North America (Prescott, ; Haslam, ). Dieter Hackenberg, David Twell, in Current Topics in Developmental Biology, The sporophyte was key for terrestrial plant evolution.
Charophyte algae developed a haplontic life cycle, in which the haploid stage is multicellular and the only diploid stage is the unicellular zygote (Shaw, Szovenyi, & Shaw, ).The haplodiplontic life cycle, which involves the alternation of.
Contrast to phosphorus, the effects of high ammonium concentrations on charophyte plants received less attention, although additions of as much as 10 mg L NH 4 + have been shown to stimulate shoot elongation of Chara spp. while additions of concentration higher than 10 mg L NH 4 + reduced shoot elongation (Simons et al., ).

Biomass of the submersed macrophyte Vallisneria americana rose steadily from early June to 50 g dry wtm−2 in ealry August. Leaves dominated the biomass of this perennial from mid-June through August, after which plants senesced to leave only winter buds as perennating organs.
Only 24% of plants sampled flowered during the growing season, yielding a population mean of less than % of. Chara vulgaris showed highest range of all elements including heavy metal contents but these values were within the recommended limits given in Food and Nutrition Board of USA, Significantly high calcium (%) comparable to calcium found in marine algae was detected from Chara vulgaris (Hussain et al., ).
Chara fragilis and Chara vulgaris were grown in a natural medium containing sodium phosphate at different levels. The H 2 PO 4 − ions, at a concentration of 2 mmol/l, are beneficial for the growth of Chara toxic effect of H 2 PO 4 − appears at 5 mmol/l. Tolerance of Chara vulgaris is inferior.
The phosphorus content of the plants were somewhat higher by increasing. The sublethal toxic effects of cadmium on Chara vulgaris have been documented in detail (Heumann, ), with a lethal dose (7 d) being only μM (56 μg l −1), and these are consistent with its significant independent effect on the field distribution of charophytes.
Phosphorus is an essential macromineral, meaning to be healthy you must include this nutrient in your diet. Dietary sources include almost all foods. Phosphorus is the second most abundant mineral nutrient in the body, after calcium.
This mineral is part of all cells, especially cell membranes, and is essential to bone strength, because it’s the [ ]. A genus of green plants in the family CHARACEAE, phylum STREPTOPHYTA.

Altogether twenty nine species of algae including one of them macro-algae Chara vulgaris L. were revealed in the Arbel stream. Chara was found in massive growth in the middle part of studied stream.

FAO Fertilizer and Plant Nutrition Bulletin Food Agricultural Organization of the United Nations, Rome.Four farm ponds in various stages of Chara vulgaris succession -from the initial invasion of the alga to its nearly complete replacement-were followed each week from ice cover to ice cover.
Chemical, physical, and biological parameters were analyzed in order to determine differences between ponds and to discover the biological and physicochemical factors associated with succession in Chara.Lakes represented the entire spectrum of ecological status (macrophyte EQR –) and trophic conditions, with mean growth season total phosphorus (TP) in the global dataset ranging from to mg L −1, total nitrogen (TN) from to mg L −1, chlorophyll a (chl-a) from to µg L .
