Aquaporins (AQPs) are essential channel proteins that execute multi-functions throughout plant growth and development, including water transport, uncharged solutes uptake, stress response, and so on. Here, we report the first genome-wide identification and characterization AQP (BvAQP) genes in sugar beet (Beta vulgaris), an important crop widely cultivated for feed, for sugar production and for...

This study concerned the degree to which Na or Rb could substitute for K in the growth of sugar beet plants when K in the culture solution was low (1 meq/liter) or high (12 meq/liter).Sodium at high concentrations increased the growth of plants in a basal nutrient medium when either deficient in K or when adequately supplied with K alone. Redistribution of K from petioles to blades could not fu...

Salinity is one of the major abiotic stresses that limit the growth and productivity of sugar beet (Beta vulgaris L.). To improve sugar beet's salinity tolerance, the ZxNHX and ZxVP1-1 genes encoding tonoplast Na(+)/H(+) antiporter and H(+)-PPase from xerophyte Zygophyllum xanthoxylum were co-expressed by Agrobacterium tumefaciens-mediated transformation. It is showed here that co-expression of...

in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...

Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

in order to investigate the impact of government policies on supply, cropping area and yield of sugar beet during 1981-2003, nominal rate of protection (nrp) was applied as a variable to persuade government’s policies in this study. results showed that despite of its negative impacts on cropping area, the nrp has positive effects on supply and yield of sugar beet iniran. moreover, real price of...

cover type of on–farm storages has an important role in reducing the freezing damage and respiration of beet roots in the pile. this experiment was conducted in 2006 in karaj region in order to evaluate the effects of cover types of storage on the mass and sugar losses of both topped and untopped beets. the experimental design was a split plot factorial in rcbd with three replications. the main...

in order to study the effective factors in sugar beet production, evaluation of technical, allocative and economical efficiency of sugar beet producers in bardsir city, 150 sugar beet producers were questioned by classified method. data were collected through questionnaire forms filled by producers in 2004-05. the stochastic frontier production and cost function method were used to analyze the ...
