to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...

At the early vegetative growth stage, mungbean are mostly affected by drought, and it is also one of most promising stages that can be used to screen for drought stress tolerance traits in multiple varieties. Therefore, this study utilized polyethylene glycol (PEG-6000) induce towards selection varieties their stage using both hydroponics soil based systems. In study, leaf wilting index respons...

The developmental stage has an influence on the overall responses of plants under biotic or abiotic stress conditions. However, there is a lack of data about the effects of ionizing radiation in plants at different developmental stages. We examined radiation sensitivity of Arabidopsis plants in terms of photosynthetic ability and oxidative stress resistance at two distinct vegetative and reprod...

to study the effect of glyphosate application rate and timing on johnsongrass (sorghum halepense) vegetative and reproductive growth, three experiments were conducted in field, greenhouse, and laboratory in the agronomy department of university of tehran, karaj, in 2007 & 2008. in each experiment, treatments were arranged in completely randomized (greenhouse & laboratory) and completely randomi...

High temperature is the prevalent characteristic of subtropical and tropical regions and higher temperature has become an important limiting element for tomato production and yield. Although, tomato crops exhibit anatomical, morphological, physiological, phonological, and molecular responses to tackle with heat stress, but their reproductive stage and yields are extremely influenced by the high...

The cysteine2/histidine2-type zinc finger proteins are a large family of transcription regulators, and some of them play essential roles in plant responses to biotic and abiotic stress. In this study, we found that expression of C2H2-type ZINC FINGER OF ARABIDOPSIS THALIANA6 (AtZAT6) was transcriptionally induced by salt, dehydration, cold stress treatments, and pathogen infection, and AtZAT6 w...

Abstract Millets are important agricultural crops for arid regions due to short life span and their resistance to salinity and drought conditions. In Iran, three main species of millets including proso millet (Panicum miliaceum), foxtail millet (Setaria italica) and pearl millet (Pennisetum glaucum) are cultivated in Shouthern Khorasan province, eastern Iran. In order to assess inter-specific...
