Since Kuhn & Jerchel (1941) showed that tetrazolium salts were reduced by bacteria, yeasts and germinating seeds, 2:3:5-triphenyltetrazolium chloride or bromide has come into prominence as a viability testing reagent (Cottrell, 1947) and for vital staining (Mattson, Jensen & Dutcher, 1947). Its specific advantages for this purpose and for the purposes which follow lie in its Eo value of -008 V....

Soluble sugars, especially sucrose, glucose, and fructose, play an obviously central role in plant structure and metabolism at the cellular and whole-organism levels. They are involved in the responses to a number of stresses, and they act as nutrient and metabolite signalling molecules that activate specific or hormone-crosstalk transduction pathways, thus resulting in important modifications ...

Studies show that Oryza sativa L. contains a structure named β-glucan with anti cancer properties. In the present study, a tissue culture for rice was carried out and β-glucan content was measured under various sugar and vitamin levels in basic MS medium. Seeds of Hashemi cultivar were cultured on MS medium. Two plant hormones, namely, 2,4-D (0, 1, 1.5, 2 and 3 mg/l) and kinetin (0,0.5, 1, and ...

in order to investigate the effects of supplementary calcium chloride and potassium nitrate on plant growth of ammi (carum copticum l.) in different salinity levels and nutrient solutions (ns), an experiment based on randomized complete block design (rcbd) with factorial arrangement was conducted under greenhouse condition in the faculty of agriculture, vali-e-asr university of rafsanjan, durin...

in order to investigate the effect of cycocel on different growth aspects of two olive cultivars (mary and mission), a greenhouse experiment was conducted taking into account three factors of: cycocel at three levels (0, 500 and 1000 mg l-1), drought stress of three levels (irrigated at 5, 10 and 15 days intervals) and two olive cultivars (mary and mission) in a factorial experiment based on ra...

The impact of water stress on antioxidant enzyme activities, proline, soluble sugars, and carotenoids contents found in Digitaria commutata Cenchrus ciliaris plants was investigated. Two different watering regimes were used over a period three months. Water decreased total chlorophyll content plants, but increased content. Interestingly, no change observed the quantum yield PSII photochemistry ...

Genetic parameters for 54 carcass and chemical traits, such as general composition (moisture, crude fat and crude protein), fatty acid composition and water-soluble compounds (free amino acids, peptides, nucleotides and sugars) of 587 commercial Japanese Black cattle were assessed. Heritability estimates for carcass traits and general composition ranged between 0.19-0.28, whereas those for fatt...

Cereal Chern. 75(1):100-104 Correlations among grain sorghum quality factors (proximate composition, physical properties, and water absorption properties) were evaluated. Samples of 46 commercial hybrids (24 and 22 from crop years 1993 and 1994) were analyzed for starch, protein, crude free fat, test weight, absolute density, 1,000 kernel weight, percent kernel abraded, water absorption index, ...
