the effect of seed inoculation by phosphate solubilizing microorganisms on growth, yield and nutrient uptake of maize (zea mays l. sc. 704) was studied in a field experiment. this experiment was conducted in meshkin abad experimental station during 2005. the experiment design consisted of four randomized complete blocks in a split-factorial arrangement. the main-plots regarding simulating water...

In this study, responses of rice under drought stress correlating with changes in chemical compositions were examined. Among 20 studied rice cultivars, Q8 was the most tolerant, whereas Q2 was the most susceptible to drought. Total phenols, total flavonoids, and antioxidant activities, and their accumulation in water deficit conditions were proportional to drought resistance levels of rice. In ...

cyphomandra betacea (cav.) is a native species from south america that is cultivated because its fruits have a high content of vitamins. in colombia, it is common to find periods of drought between the rainy seasons or during enso events such as el niño. an adequate nutritional status of k+ in plants helps to increase the chance of tolerating the negative effects of drought stress. regarding th...

The worldwide usage of and increasing citations for ORYZA2000 has established it as a robust and reliable ecophysiological model for predicting the growth and yield of rice in an irrigated lowland ecosystem. Because of its focus on irrigated lowlands, its computation ability is limited to the representation of the effects of the highly dynamic environments of upland, rainfed, and aerobic ecosys...

The binding protein (BiP) is an important component of endoplasmic reticulum stress response of cells. Despite extensive studies in cultured cells, a protective function of BiP against stress has not yet been demonstrated in whole multicellular organisms. Here, we have obtained transgenic tobacco (Nicotiana tabacum L. cv Havana) plants constitutively expressing elevated levels of BiP or its ant...

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 ...

terminal drought stress during grain filling period has recently become more common in the semiarid mediterranean regions, where wheat (triticum aestivum) is grown as an important winter cereal crop. the objective of this experiment was to study the effect of terminal drought stress on grain yield, gas exchange variables, and some physiological traits of nine bread wheat cultivars. an experimen...
