The present study was carried out to investigate the effects of solution concentration, immersion time and temperature on the osmotic dehydration (OD) of summer onion. OD was done using sucrose, salt and combined (sucrose-salt) solution. In this study three sucrose (40,50 and 60%), five salt (5,10,15,20 and 25%) and five sucrosesalt (combine) solution (40:15, 45:15, 45:20 50:15 and 55:15 %) wer...

Aim. Analysis of physiological and biochemical characteristics genetically modified wheat with partially suppressed activity the proline dehydrogenase gene. Methods. Determination (PDH) activity, free L-proline (Pro); carbohydrate content (sucrose fructose). Results. It was established that under conditions water deficit in plants integrated elements forming double-stranded RNA suppressor pdh g...

Onion and shallot (Allium cepa L.) exhibit wide variation in bulb fructan content, and the Frc locus on chromosome 8 conditions much of this variation. To understand the biochemical basis of Frc, we conducted biochemical and genetic analyses of Allium fistulosum (FF)-shallot (A. cepa Aggregatum group) alien monosomic addition lines (AALs; FF+1A-FF+8A) and onion mapping populations. Sucrose and ...

The radiation of 14C is very weak 14C+ 14N t PSucrose in first expressed juice and mixed juice was determined by isotope dilution and the results were compared with the conventional pol determination. i t was found that the sucrose content on the average was 0,25% higher using the ID method. Molasses samples, on the contrary, showed a sucrose content which was 0,71% lower than the value found b...

The entry of carbon from sucrose into cellular metabolism in plants can potentially be catalyzed by either sucrose synthase (SUS) or invertase (INV). These 2 routes have different implications for cellular metabolism in general and for the production of key metabolites, including the cell-wall precursor UDPglucose. To examine the importance of these 2 routes of sucrose catabolism in Arabidopsis...

The effects of citric acid on the curing properties of tannin-sucrose adhesives and on the physical properties of particleboard utilizing the adhesives were investigated. The citric acid content of tannin-sucrose adhesive was adjusted to 0.4, 1.8, 4.6, 13.8, 20.0, and 33.3%, which corresponded to pH values of the adhesive 40 wt% solution at 3.8, 3.0, 2.5, 2.0, 1.8, and 1.5, respectively. Therma...

The roots of barley plants (Hordeum vulgare L. cv Steptoe) were monitored before and after excision for net uptake of carbon dioxide, oxygen, ammonium, potassium, nitrate, and chloride and for their content of sucrose, glucose, fructose, and malic acid. All fluxes began to attenuate within 2 hours after excision. Net potassium uptake returned to control levels 6 hours after excision, but carbon...

The Sugar Research Institute (SRI) in Australia provided the SMRI with a Sucrose Analyser for evaluation. Although the Sucrose Analyser is designed for online measurement of sucrose concentrations, this application describes the direct measurement of sucrose in factory streams in a laboratory environment. The Sucrose Analyser provides a quick and cost effective way of estimating the sucrose con...

Saccharum officinarum is one of the most cultivated hybrid varieties among the sugarcane varieties. In sugarcane plant sucrose is the major carbohydrate which can be stored and transported. Different physiological and biochemical studies on this crop report that invertase activity and sucrose concentration some how are key limiting step in the process of sucrose accumulation. Significant effort...

Large-panicle rice cultivars often fail to reach their yield potential due to the poor grain filling of inferior spikelets (IS). Thus, it is important to determine the causes of poor IS grain filling. In this study, we attempted to identify whether inferior grain filling of large panicles is restricted by superior spikelets (SS) and their physiological mechanism. SS were removed from two homozy...
