The optimization of nitrogen application for root crops such as radish is important not only for yield and product quality (sponginess and hollowness) but also for the environment. Therefore, we evaluated the effect of four levels of N application (0, 150, 300 and 450 mg l-1 N) on three radish cultivars (Saxa, Red Fuoko and White Ghiaccio) grown in pots in autumn/winter (from mid-October to mid...

Five Malaysian rice (Oryza sativa L.) varieties, MR33, MR52, MR211, MR219, and MR232, were tested in pot culture under different salinity regimes for biochemical response, physiological activity, and grain yield. Three different levels of salt stresses, namely, 4, 8, and 12 dS m(-1), were used in a randomized complete block design with four replications under glass house conditions. The results...

In Saccharomyces cerevisiae, maltose is transported by a proton symport mechanism, whereas glucose transport occurs via facilitated diffusion. The energy requirement for maltose transport was evaluated with a metabolic model based on an experimental value of YATP for growth on glucose and an ATP requirement for maltose transport of 1 mol.mol-1. The predictions of the model were verified experim...

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...

Sugar beet (Beta vulgaris L.) is a valuable sugar-providing crop accounting for around 25% of global white sugar production. It an integral part the food industry. Several factors cause decrease in yield this crop. The infection phytopathogenic fungi one most hazardous. Though several methods to control Rhizoctonia solani have been developed, problem still not solved. Thus, goal work was invest...

in order to study the effect of genotype × environment interaction and stability of sugar beet varieties, four cultivars, including shirine, zarghan, laetitia and 7112 hybrid were planted in five major areas near to sugar beet factory of biseton as kangavar, sahneh, chamchamal, dinavar and ravansar for three years (2006-2008) using a randomized complete block designs, with three replications. a...

in semiarid regions of iran, one of the crop production management methods is delayed irrigation after emergence. this is due to simultaneous water requirement of cereal and spring season crops. a field study was conducted in kabootarabad research station to investigate the effect of delayed irrigation on root yield, quality and growth trend using a rcb with four replications. the irrigation tr...
