a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Seed vigor is a complex property that determines the seed's potential for rapid uniform emergence and subsequent growth. However, the mechanism for change in seed vigor is poorly understood. The seeds of poplar (Populus × Canadensis Moench), which are short-lived, were stored at 30 °C and 75 ± 5% relative humidity for different periods of time (0-90 days) to obtain different vigor seeds (from 9...

To evaluate the effect of priming on seed germination of Cucurbita pepo in drought stress conditions, a factorial experiment was conducted as completely randomized design with three replications. Treatments included drought stress at five levels of osmotic potential (zero, 0.3, 0.6, 0.9 and 1.2 MP), priming at levels of GA3 (250 ppm to 24 hours), KNO3 (0.2% for 24 hours) Hydro prime (H2O) (to 2...

this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...

Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...

sesame is one of the most important oil crops in iran. high oil seed content makes it difficult to store for a long period of time. this study was conducted in 2012 to evaluate possible physiological and biochemical changes in seed under different storage conditions. various seed moisture content (5, 9, 13, and 17%) were evaluated under five temperatures (5, 15, 25, 35, 45) for six month. germi...

We investigated the prevalence of seed borne fungal pathogens in rice variety BRRI Dhan46 and to evaluate the efficacy of antagonistic bacteria in controlling seed borne disease. A composite sample of BRRI Dhan46 was assayed. Five seed borne fungi viz. Fusarium sp., Bipolaris oryzae, Curvularia sp., Gliocladium sp. and Aspergillus flavus were isolated from the rice seeds. Fifteen probable antag...

Effectof exopolysaccharides (EPS) produced by a consortium of cyanobacteria on germination of three crops wheat, maize and rice was studied at different salt concentrations. Production of EPS was found to be stimulated by salts, which in turn had a significant Na+ removal capability from aqueous solution. Seed germination, vigor index and mobilization efficiency in all the three crops remarkabl...

the ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...
