Five Malaysian rice (Oryza sativa L.) varieties, MR33, MR52, MR211, MR219, and MR232, were tested in pot culture under different salinity regimes for biochemical response, physiological activity, and grain yield. Three different levels of salt stresses, namely, 4, 8, and 12 dS m(-1), were used in a randomized complete block design with four replications under glass house conditions. The results...

BACKGROUND Soluble sugars are involved in responses to stress, and act as signalling molecules that activate specific or hormone cross-talk transduction pathways. Thus, exogenous sucrose treatment efficiently induces tolerance to the herbicide atrazine in Arabidopsis thaliana plantlets, at least partially through large-scale modifications of expression of stress-related genes. METHODS Availab...

The aim of the study was to assess whether an extra fertilization with manganese, commercial fertilizer Alkalin (N, K and Si), and combined treatment (manganese + Alkalin) affect the chemical composition of chokeberry fruits (Aronia melanocarpa (Michx) Elliot), especially sugar content and the quantity and profile of phenolics. Dry weight, soluble solids, titratable acidity, total sugar, reduci...

Cataract is the leading cause of blindness worldwide. Apart from ageing, diabetes has been considered to be one of the major risk factors of cataract. The high sugar levels in diabetes may cause tissue disruption and intumescences by osmotic changes induced via aldose reductase (AR) mediated polyol pathway. Therefore, agents that can inhibit AR and prevent sorbitol accumulation may be helpful t...

Soluble sugar composition of developing soybean seed (Glycine max L. Merr.) vary with cultivar. This study was conducted to determine the relation between soluble sugar accumulation and associated enzyme activities in developing seed of two soybean cultivars, Williams 82 and Wolverine. Activities of sucrose synthase, invertase, galactinol synthase, and a-galactosidase were compared to soluble s...

The effects of temperature, light, oxidant, soluble sugar, food additive (i.e. citric acid, benzoic acid, and ascorbic acid) and metal ions of K, Ca, Cu, Al, Mn, Fe, Sn, Mg on the stability of anthocyanin extracted from the kernels of novel inbred line super dark maize (SDM) with the strategy of HCl-carbinol were systematically analyzed. The results showed that the extracted anthocyanin was ste...

Soluble sugar and malic acid contents in mature fruits of 364 apple accessions were quantified using high-performance liquid chromatography (HPLC). Fructose and sucrose represented the major components of soluble sugars in cultivated fruits, whilst fructose and glucose were the major items of sugars in wild fruits. Wild fruits were significantly more acidic than cultivated fruits, whilst the av...

Two green kohlrabi cultivars, ‘White Delikates’ and ‘Korist’ F1, were kept in cold storage at a temperature of 2oC and a relative humidity of 95%. Natural mass losses were measured at monthly intervals and dry matter content, soluble sugars, L-ascorbic acid and isothiocyanates were analysed. During five months of storage, very low losses of kohlrabi mass were detected. The decrease in dry matte...

Palm sap tapped from three varieties of date palm Phoenix dactylifera was analyzed during two tapping periods: winter and springtime. These samples were collected once-a-week during 14 weeks for each tapping period. Total soluble solids decreased during tapping period; however no significant variation was noted for pH and titrable acidity. The microbial count indicated that after an initial hig...

The study investigated the pH, acidity, soluble solids, total sugar, polyphenol, flavonoid, anthocyanin content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, and color of kombucha with a variety added fruit peels during fermentation process. Pear, grape, plum, orange, apple, golden kiwi were fermentation. pH showed decrease, while an increase in acidity was observed. An which higher...
