such a galactosyl transfer reaction as well as the decomposition of raffinose in beet sugar production, they may also produce galactooligosaccharides. Mitutomi and OhtakaraX) reported the isolation and identification of six main oligosaccharides produced from raffinose by the action of the a-galactosidase from Pycnoporus cinnabarinus. In our preliminary experiments, however, the a-galactosidase...

water is the most important factor for agriculture development in iran. accordingly the optimal consumptione of water is very important. using pressurized irrigation system is one of the methods to improve agricultural water management. the objecttives of this research were to compare two irrigation methods of furrow and trickle irrigation systems impacts on quantity and quality characters of s...

Ammonium sulfate, ammonium carbonate or ammonia gas inhibited water uptake in sugar beet roots whenever the pH was sufficiently high to cause the production of ammonia. When ammonia was removed by aeration, inhibition of the water uptake by roots was rapidly reversed. ATP at 0.2 mm appeared to either wholly or partially prevent the ammonia-induced inhibition of water uptake by roots. ATP may be...

saving in irrigation water is important in the early season of sugar beet. the effect of early season deficit irrigation on the sugar beet growth indexes was investigated in kabotarabad agricultural research station (esfahan) in 1998. the soil texture was silty clay and the experiment design was randomized complete block with 4 relications. six irrigation regimes were applied after. 1) 100 mm (...

cluding California (Altman and Thomason, 1971; Whitney and Duffus, 1986; Duffus and Ruppel, 1993). Resistance to root-knot nematode (Meloidogyne spp.) previously Disease of sugar beet caused by root-knot nematode was introgressed into sugar beet (Beta vulgaris L.) from wild beet [B. vulgaris ssp. maritima (L.) Arcang] and was demonstrated to be is manifested by galls that form on lateral roots ...

understanding the relationship between root yield and other traits in sugar beet may be a crucial step towards successful breeding of this important crop. path analysis provides a useful method in analyzing the genetic and phenotypic coefficients of correlations. this method is able to effectively unveil direct and indirect effects among traits of interest. in this research, root yield, yield c...

background and objectives: sugar beet (beta vulgaris l.) is the major crop in khorasan province which is mainly grown in spring. however, autumn sowing has a lot of advantages including lower crop water requirement and higher water use efficiency. accordingly, this research was performed to compare the yield of storage organ in spring and autumn-sown sugar beet and determine the most appropriat...

the main purpose of this study was to measure the level of technical efficiency of sugar beet producers and determination of factors affecting it. a sample of 144 producers in the main sugar beet growing areas of hamedan, nahavand, malayer and asadabad were selected by two stage cluster sampling method. data were collected through interviews during farming year of 2001-2002.technical efficiency...

In this study fungi isolated from the effluent of ethanol factories were identified. Optimal conditions for single cell protein (SCP) production and COD reduction of sugar beet stillage are specified for a species of Hansenula in a continuous culture. Under these conditions 5.7 g dm-3 biomass was produced and 31% of COD was reduced without addition of further nutrients to the beet molasses ...
