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 this study, analysis of actual data collected from sugar beet hybrid monogerm seed producers in the 2001 growing season and laboratory seed samples showed that delay in steckling sowing resulted in the reduction of raw and pure sugar beet seed yield and the increase of undersize seed portion. non-significant effect of sowing dates on unkernel seed percent showed that the high temperatures wi...

resistance of 16 sugar beet cultivars to cercospora leaf spot was evaluated in ghaemshahr region. the experiment was conducted in a complete block design with 6 replications, and, disease severity of cultivars was measured two times. root yield of cultivars, as well as their disease severity, was compared with each other under natural cercospora infection in dezful area (winter crop). in dezful...

in order to identify and selection salt tolerant hybrids based on tolerance indices, 17 sugar beet three-way cross hybrids produced by crosses between 17 salinity improved s1 pollinators and a cytoplasmic male sterile (cms) single cross as female, along with three control genotypes were grown in 2007 in rudasht station (isfahan) under saline (12 ds/m and 8 ds/m for water and soil) and non-salin...

the study was conducted during 2002- 2007 in the first and last stage of a four-year rotation (sugar beet, forage maize, onion, wheat and sugar beet) at research station of irrigation and drainage rudasht. in each year, four treatments of organic fertilizers (25 and 50 t/ha urban compost and 15 and 30 t/ha sewage sludge) with a control (no organic fertilizer) were studied in a randomized comple...

Sweet sorghum [Sorghum bicolor (L.) Moench] is characterized by juicy stems with high concentrations of fermentable sugars. The genetic basis of these phenotypes is not understood. A sweet sorghum diversity panel (n = 252), consisting of sweet sorghum cultivars (n = 80) and diverse landraces selected for matching plant height and maturity (n = 172), was genotyped and phenotyped in three environ...

The pyridylamination method is useful for the structural unalysis ef sugar chains from smal] arnounts of glycoproteins. About 60(;・g of the sialyl linkage was, however, hydrolyzed under the reaction conditions reported previously.i2) The grewing need for fluorescence labeling of sialyl sugar chains prompted us to re-investigate the reaction conditions. Recently. wc tried pyridylamination condit...
