This experiment was carried out to evaluate the effect of silver nanoparticles pulsing treatment (0, 25, 75 and 125 mg L−1) on vase life and some postharvest physiological parameters of cut rose flower ʻHigh & Magicʼ in sucrose solution (0, 2 and 3%). This research performed as a factorial experiment based on a completely randomized design with three replications under 23 ± 2 °C, 60 ± 5% RH and...

Seventeen Thermomyces lanuginosus strains, cultivated on raffinose and sucrose, were ranked on the basis of -galactosidase activities. T. lanuginosus CBS 395.62/b strain showed the highest -galactosidase activity on both investigated carbohydrates. Several carbon sources were tested as potential inducers for the -galactosidase synthesis. On melibiose substrate -galactosidase activity was higher...

background: development of safe radioprotector is a challenging task. in this study radioprotective effect of sucrose has been demonstrated in calf thymus dna (ctdna). sucrose is a free radical scavenger and also acts as osmolyte and therefore can influence the water activity around dna and effects of radiation on dna. hoechst 33258 was used to probe the possible alteration in physicochemical p...

Net sucrose efflux from discs of fully expanded leaves of soybean (Glycine max [L.] Merr.) plants was studied to characterize sucrose efflux into the apoplast. Net sucrose efflux had a Q(10) of 2.3, was linear for at least 3.5 hours, and was selective for sucrose over glucose. Sulfhydryl group inhibitors reduced sucrose efflux by up to 80%. There was a biphasic promotion of sucrose efflux by KC...

Enzymatic synthesis of sugar fatty acid esters were performed in an organic solvent using Immobilized Rhizomucor miehei (RMIM) lipase with sucrose and non-edible rice bran fatty acid as substrates. The maximum conversion of sucrose esters up to 78% obtained when sucrose and non-edible rice bran fatty acid were reacted in molar ratio of 1:8, using n-butanol as a solvent and 1% molecular sieves w...

In the current study, a simple cryopreservation method (desiccation) was applied to Corylus avellana L. callus. Accordingly, effects of abscisic acid (ABA) concentration, pretreatment duration on MS medium containing ABA + 10% sucrose, and storage length in liquid nitrogen (LN) callus survival rate were investigated. Calli’s assessed 8 weeks after exiting from LN. Callus significantly affected ...

M14late is a key intermiie(liate in converting acetyl units to sucrose in germinating castor beans (8). In an earlier paper evidence wsas presente(d to show that a mechanism exists for the pro(luction of phosphoenol-pyruvate from nmalate in this material andl that phosphoenol-I)yruvate is an interme(liate in the production of sucrose fromii malate (6). In this paper indivi(lual reactions which ...
