Chromium is a heavy metal toxic for plants that due extensive industrial applications over the last decade, has become a serious environmental pollution. On the other hand, chelator dissolution and absorption of metal by the plant increase and their use in phytoremediation is important. The aim of this study was to evaluate the effect of different concentrations of chromium and ethylene diamine...

Starch and soluble sugars are the major photosynthetic products, and their carbon isotope signatures reflect external versus internal limitations of CO(2) fixation. There has been recent renewed interest in the isotope composition of carbohydrates, mainly for use in CO(2) flux partitioning studies at the ecosystem level. The major obstacle to the use of carbohydrates in such studies has been th...

BACKGROUND AND AIMS Benefits to crop productivity arising from increasing CO2 fertilization may be offset by detrimental effects of global climate change, such as an increasing frequency of drought. Phosphorus (P) nutrition plays an important role in crop responses to water stress, but how elevated CO2 (eCO2) and P nutrition interact, especially in legumes, is unclear. This study aimed to eluci...

The effects of kinetin on starch and sugar levels and on (14)CO(2) and (32)P-orthophosphate labeling patterns of floated Chinese cabbage (Brassica pekinensis) leaf discs were investigated. Kinetin caused gross starch degradation. Neutral sugars were depressed by 30 to 40% in leaf tissue treated with kinetin for 24 hours. (14)CO(2) labeling of leaf discs pretreated with kinetin for 24 hours show...

‘Smyrna’ type figs (Zidi ‘ZD’: dark fruit and Thgagli ‘THG’; Bidhi ‘BD’ and Khedri ‘KHD’: white fruit) originated from two areas of fig production in Tunisia were subject to physico-chemical description and spectrophotometric analysis for their sugar (glucose, fructose and sucrose) and organic acid (citric and malic) contents. Fruit weight ranged between 54 and 82 g, fruit width between 47 and ...

ABSTRACT. Teff [Eragrostis tef (Zuccagni) Trotter] is cereal grain native to Ethiopia as staple food millions of people. However, no research work has been reported for characterization with respect water-soluble total sugars and free amino acids in white brown teff grains. The main objective this study was determine (TFAA) the varieties. determined sugar contents sample extract ranged between ...

BACK GROUND For enzyme production, the costs of solid state fermentation (SSF) techniques were lower and the production higher than submerged cultures. A large number of fungal species was known to grow well on moist substrates, whereas many bacteria were unable to grow under this condition. Therefore, the aim of this study was to isolate a highly efficient strain of Bacillus sp utilizing wheat...

In this research, the response of shoot and root of two cultivars of soybean (Glycine max L. cvs Gorgan 3 & Williams) to mild and severe drought was evaluated in pot. Two weeks after of planting, three irrigation treatments including every day (as control), once in three (as mild stress) and five days (as severe stress) were used. The results showed that, stem dry weight, stem and root length, ...

It has been suggested that respiratory stress is involved in the mechanism underlying the dormancy-breaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels (hypoxia) and inhibitors of respiration promote bud-break in grapevines. In this study, we showed that, hypoxia increased starch hydrolysis soluble sugar consumption and up-regulat...

Five varieties of cowpea (Vigna unguiculata) were analysed for their proximate composition, major mineral elements and carbohydrate fractions. Values crude protein ranged from 25.80% to 28.95% while the ether extract, fibre, total ash had following values: 1.83 - 2.37%, 3.06 4.48%, 5.80 7.10% 50.46 55.76% respectively. The average values phosphorus, calcium, magnesium, potassium sodium 0.400%, ...
