in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...

This experiment was conducted to investigate of drought effect on some physiological parameters and amino acids accumulation in two canola cultivars (SLM046 and Cooper; tolerance and sensitive to water stress, respectively). The experiment was carried out during two growth phase (stem elongation and flowering stage) using irrigation levels consisting of irrigation after 80 mm evaporation from c...

Floral transition through vernalization has a large influence on cold tolerance and agronomic traits in winter cereals. It is now apparent that in many plants small RNAs play critical roles in determination of the flowering time. There is evidence suggesting that the miR156 and miR172 families play a key role in the flowering transition of plants. In this study, the expression of two temporally ...

To investigate the effect of different irrigation levels on yield and yield components of two cotton cultivar, a two-year experiment (2006-2007) was carried out at Agricultural Research Center of Kabotarabad, Isfahan, Iran. In this experiment, the strip split-plot design, as randomized complete blocks with four replications, was used. Main plots consisted of six levels of irrigation (T1 to T6, ...

In order to study chemical weed control in cycloxydim tolerant maize (CTM) using cycloxydim herbicide, an experiment was carried out in a randomized complete block design with three replications during 2014. Treatments included conventional corn herbicides application (Nicosulforun, Foramsulfuron, Eradican and 2, 4-D + MCPA) in their recommended doses and combined treatment of cycloxydim + (dic...

To evaluate the effects of drought stress by withholding of irrigation during reproductive stages and foliar application of micronutrients (Zn, Mn and B) on seed yiled and oil quality, an experiment was carried out as split plot arrangements in randomized complete block design with three replications at Safiabad Agricultural and Natural Resources Research and Education Center, Dezful, Iran, in ...
