the aim of the study was to evaluate changes of sorbitol, glucose, fructose, sucrose, and total sugars of plum fruits in different years under different climatic conditions i.e. air temperature and precipitation. the cultivars investigated in the research were: topstar, toptaste, jojo, haganta, tophit, and top 2000. the fruits were harvested at optimal stage of maturity in the experimental orch...

The small-angle X-ray and neutron scattering, time resolved X-ray small-angle and wide-angle diffraction coupled with differential scanning calorimetry have been applied to the investigation of unilamellar and multilamellar dimyristoylphosphatidylcholine (DMPC) vesicles in sucrose buffers with sucrose concentrations from 0 to 60%. Sucrose buffer decreased vesicle size and polydispersity and inc...

Field-grown sugar beets were analysed for morphological characters, sucrose content, and reproducible transcript profiles by macroarray analyses with 11,520 unique sugar-beet cDNA targets in two different years. Seasonal differences were partly compensated by expressing sampling dates as thermal time. During early beet development the number of cambial rings, root length, and sucrose concentrat...

To change the hexose-to-sucrose ratio within phloem cells, yeast-derived cytosolic invertase was expressed in transgenic potato (Solanum tuberosum cv. Desirée) plants under control of the rolC promoter. Vascular tissue specific expression of the transgene was verified by histochemical detection of invertase activity in tuber cross-sections. Vegetative growth and tuber yield of transgenic plants...

xylitol is the first rare sugar that has global market due to having beneficial health properties and being an alternative to current conventional sweeteners. biotechnological production of xylitol by candida tropicalis dsm 7524 as an alternative to chemical method for the fermentation of xylose to xylitol was studied. banana peel was used as a substrate for xylitol production. hydrolysate was ...

tomatoes (roma cultivar) picked up for the study were obtained from varaminelocal market. each tomato was divided into four portions. quarter portions of tomato were placed in osmotic solutions that were different in levels of sucrose and nacl (30 and 40% for sucrose, and 5, 10 and 15% for nacl). osmotic dehydration was carried out for varied time durations from 15 up to 240 min. temperature of...

The aim of this study was to evaluate the effect of ethylene glycol (EG) concentration, equilibration time, and the use of two disaccharides in the vitrification solution used on immature bovine oocytes that were thawed and then matured in vitro. Factorial combinations of the following were tested: three equilibration solutions (ES), containing 3, 20 or 40% EG; three equilibration times, 0.5, 5...

This study investigates the effect of boric acid and sucrose on the germination and growth of Areca catechu L (areca palm). Using areca pollen from Hainan, China, this study determines the influence of culture media with different concentrations of boric acid and sucrose on the germination and growth of areca pollen. Results show that the germination and growth of the pollen tube growth are hig...

Sucrose is a necessary external carbon substrate for in vitro microtuber induction and development. In this study, we determined the correlation between sucrose and microtuber formation in potato by investigating the role and significance of sucrose in the medium and the origin of explants, as well as the potential function of sucrose in microtuber formation in vitro. Sucrose strongly influence...
