Win ISAREG is a model for performing soil water balance and estimating impacts of water stress on yields for crops, concentrating on the evaluation of irrigation scheduling. The soil water balance of different type of soil and crop were study in the typical semiarid Horqin Sandy land area in this paper. With the data from Agula experimental station and concentrate on site A3 with Artemisia and ...

BACKGROUND In the present study, the effect of dextromethorphan on antinociception and tolerance induced by water swim-stress in the formalin test was investigated. METHODS Swim-stress at 8 masculineC induces antinociception in both phases of the formalin test. Intraperitoneal administration of dextromethorphan (60 mg/kg) also induces antinociception in the second phase of the formalin test. ...

an investigation of chlorophyll quick fluorsence variations was made in the reaserch field of islamic azad university- karaj in 2007. the experimental design was a split plot one in form of a complete randomized block design with 4 replications. drought stress was cosiderded in three levels of 40%, 60%, and 75%, on the basis of depletion of soil moisture as the main factor and the factor of mic...

the importance of environmental protection in modern communities is vital, the action and implementation of any program requires the sufficient knowledge and understanding of environment. one of the methods to preserve natural resources and achieving sustainable development, especially sustainable agriculture, is the environmentally evaluation of agriculture production processes. life cycle ass...

Α two-year field experiment was conducted in Varamin-Pishva Branch, Islamic Azad University, Iran to study the impact of drought stress and foliar application some hormones on safflower growth. The induced at three levels considered as main plots. Irrigating after 75% water depletion be normal irrigation (control), irrigating 60 45% depletion, defined mild severe stress, respectively. humic aci...

BACKGROUND Memantine attenuates heart stress due cold stress, however, no study focused its effects on liver and adrenal gland. We evaluated its effects on lipid depletion in adrenal gland and glycogen depletion in liver of rats exposed to cold stress. METHODS Male rats divided into 4 groups: 1)Control (CON); 2)Memantine (MEM); 3)Induced cold stress (IH) and; 4)Induced cold stress memantine (...

Wheat growth in response to soil water deficit play an important role in yield stability. A field experiment was conducted for winter wheat (Triticum aestivum L.) during the period of 2002–2005 to evaluate the effects of limited irrigation on winter wheat growth. 80%, 70%, 60%, 50% and 40% of field capacity was applied at different stages of crop growth. Photosynthetic characteristics of winter...
