the water deficit is the most important limiting non-biological factor to achieve the potential yield of crops. to evaluate the effect of silicon application on yield of millet under drought stress in field an experimental was carried out. treatments were included three irrigation regimes after 60 (non-stress), 90 (moderate stress) and 120 (severe stress) mm evaporation from evaporation pan, cl...

to study the effect of humic acid and drought stress on some physiological characteristics of roselle (hibiscus sabdariffa) an experiment was conducted in the research field of agricultural education centre of jiroft in 2013. field experiment was carried out as split plot design with three replications. water deficit stress as main factor with three levels (a1 = irrigation after 50, a2 = 100 an...

water deficit is a major factor influencing yield of canola (brassica napus l.) seed yield and oil content. a field experiment was conducted during 2010 growing season in the agriculture research station of torogh, mashhad, iran to evaluate responses of canola cultivars to limited water. experimental design was rcbd pattern with three replications. treatments were two irrigation regimes (based ...

current study aimed at determining the most reliable drought tolerant criteria for identification of sugar beet genotypes. a split plot design based on randomized complete block design with three replications was applied at motahari research station, karaj, iran in 2012. two irrigation treatments including normal irrigation after 80-90 mm and irrigation after 270 mm evaporation (stress conditio...

the objective of the present study was to assess the combined effects of drought stress and foliar application of zinc and manganese on seed quality of red bean (naz variety) during the accelerated aging test. the experiment was carried out as split factorial in a randomized complete block design (rcbd) with three replications at the research farm of shahrekord university during 2010-2011. drou...

BACKGROUND: Drought stress and climate changes cause damage led to reduction in agricultural production. OBJECTIVES: Evaluation the impact of different levels of super absorbent polymer (SAP) on reducing the effects of drought stress on some physiological traits and activity of some antioxidant enzymes in wheat crop. METHODS: Current research...

During the long evolutionary process, plant gradually formed a series of strategies and mechanisms to cope with stress environment such as drought, heat, cold, and high salinity. Six highly heat responsive genes were identified in rice by microarray data analysis. The qRT-PCR analysis confirmed that the expression of these six genes were highly heat inducible and moderately responded to salt st...

[1] Simulations of potential vegetation distribution, natural fire frequency, carbon pools, and fluxes are presented for two DGVMs (Dynamic Global Vegetation Models) from the second phase of the Vegetation/Ecosystem Modeling and Analysis Project. Results link vegetation dynamics to biogeochemical cycling for the conterminous United States. Two climate change scenarios were used: a moderately wa...
