to evaluate the effects of methanol and drought stress on chlorophyll fluorescence parameters, chlorophyll and relative water content in sugar beet, a study was conducted in 2008 in maahdasht (karaj, iran). aqueous solutions of 0 (control), 7, 14, 21, 28, 35% (v/v) methanol with each solution containing 0.2% glycine and a second factor, namely drought stress (irrigation after 70% depletion of a...

In a four-year experiment, five nitrogen rates (0, 60, 120, 180 and 240 kg N ha-1) were tested over irrigated sugar beets grown on clays, underMediterranean conditions, in centralGreece. There, sugar beets are commonly grown under water shortages, high temperatures and high soil Na concentrations. Contrary to previous reports, N rates did not affect significantly population density (as asse...

in order to evaluate the best drought resistance indices in sugar beetgenotypes, an experiment was conducted in 2002 using a split- plot design within randomized complete block design with three replications at the research farm, shiraz-zarghan. the main plots consisted of three irrigated regimes: non stress, 75% (mid stress) and 50% (intense stress) non stress and the ten genotypes as the sub ...

as water is the most restrictive factor in national agricultural production, it is necessary to take decreased water consumption and increased water us efficiency in crop production into consideration. nowadays, spring sugar beet production areas are concentrated in the region with water limitation and hence, the increase in spring production area contradicts the principle of water and soil con...

in drought stress condition, it is important to estimate the n and k requirement of sugar beet. a drought-tolerant sugar beet genotype, bp karaj, was evaluated in split plot factorial design based on a randomized complete block design with four replications at motahari research station, karaj, iran for three years. main plots were allocated to irrigation treatments including normal irrigation (...

NIR spectroscopy was used as a non-destructive technique for the assessment of chemical changes in the main internal quality properties of wine grapes (Vitis vinifera L.) during on-vine ripening and at harvest. A total of 363 samples from 25 white and red grape varieties were used to construct quality-prediction models based on reference data and on NIR spectral data obtained using a commercial...

The options and prospects for the direct production of white sugar in a cane sugar mill are reviewed. Plantation white sugar has been made for many years in some countries but cannot meet the requirements for refined sugars. These low colour sugars are now a popular quality raw sugar for the increasing number of destination refineries. Attainment of refined sugar standards needs the application...

Water is a major constituent of food products even if it is present at a trace level as in white crystalline sugar. Molecular interactions between sugar and water are at the origin of structural as well as mechanical properties (density, compressibility, flow) of bulk sugar. Conditioning of white sugar is therefore difficult because it is sensitive to relative humidity and temperature of surrou...

The cyanobacterium Anabaena flos-aquae (strain 1444) grown at different intensities o f white light (900. 3500 and 30000 lux) showed changes in the content and com position o f the pigments. Phycocyanin was more affected by high light conditions during growth than chlorophyll a. In comparison to in low white light grown cyanobacteria number o f phycobilisom es and thylakoids decreased under str...

in order to study the reason for the prominent increase of the average of sugar content in sugar beet produced in iran in 2007 and finding the relation of this increase with climatic parameters, chenaran sugar factory district was chosen. due to precise and reliable statistical data of sugar factory during the campaign and weather data, chenaran sugar factory was chosen for this investigation. ...
