this study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (triticum aestivum l.) cultivars (azar2, darab2, shiraz, and falat) inoculated with the fungus glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the school of agriculture, shir...

an experiment was conducted to determine the effect of paclobutrazol (pbz) and different irrigation amount on growth of aerial parts, leaf minerals and root performance in young olive plants cv. ‘manzanillo’ in the department of horticulture, faculty of agriculture, tarbiat modarres university in 2000. a split plot experiment in time was used based on a completely randomized block design with f...

The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...

In order to investigate the effect of drought and salinity stress on caper plant (Capparis spinosa), a factorial experiment including two factors consisting of drought and salinity levels based on randomized complete block design (RCBD) with five blocks were carried out at College of Agriculture, Shiraz University, Shiraz, Iran. After pretreatment, seeds were germinated in petri dishes and then...

Plant polyphenols have gained prominence in quality of plant products and in human health. An experiment was conducted to determine the association of tea polyphenols with water stress and their suitability as indicators for drought tolerance. The experiment was conducted in a 'rain-out' shelter, and consisted of six tea clones (BBK 35, TRFK 6/8, TRFK 76/1, TRFK 395/2, TRFK 31/30, and TRFK 311/...

Potassium in plants accounts for up to 10% dry weight, and participates in different physiological processes. Under drought stress, plant requires more potassium but potassium availability in soil solutes is lowered by decreased soil water content. Forming symbiosis with arbuscular mycorrhizal (AM) fungi not only enlarges exploration range of plant for mineral nutrients and water in soil, but a...

effects of water stress and fusarium oxysporum f. sp. lycoperseci (fol) on the growth of tomatoes were studied in a greenhouse experiment. treatments consisted of five levels of water stress (1, 3, 5, 7 and 9 day irrigation intervals). infested soil consisting of 400 chlamydospores g1 of fol and non infested soil were used. experiments arranged in a completely randomized design with 8 replicati...

During spring storms massive uprooting of Littorella uniflora occurred in a shallow Dutch softwater lake. The aim of this study was to test whether changes in plant morphology and sediment characteristics could explain the observed phenomenon. Uprooting was expected to occur in plants having a high shoot biomass and low root to shoot ratio (R:S), growing on sediments with a high organic matter ...
