Background Soil moisture deficiency causes yield reduction and instability in faba bean (Vicia faba L.) production. The extent of sensitivity to drought stress varies across accessions originating from diverse moisture regimes of the world. Hence, we conducted successive greenhouse experiments in pots and rhizotrons to explore diversity in root responses to soil water deficit. Methods A set o...

abstract in this study, interaction between amf (g. mosseae and glomus spp., respectively indigenous and non-indigenous of hm-contaminated areas) with cd-resistant pgprs (bacillus mycoides and micrococcus roseus, indigenous of contaminated areas) on the growth, cd and nutrient uptake of maize plant (zea mays l.) in cd polluted soil were investigated. with increasing levels of cd, shoot and root...

This research was carried out to evaluate the effect of two mycorrhiza species on growth, yield and oil content of geranium under salinity stress. The experiment was done at research greenhouse of Faculty of Agriculture, Lorestan University, Iran, in 2014. Four levels of substrate (sterilised and non-sterilised control soil and sterilised soil inoculated with Glomus mosseae or G. intraradices),...

Plant growth and development was affected greatly through salinity. Appropriate nutrients application on salinity condition can reduce its harmful effects and increased productivity of salinized soils. A pot experiment was carried out in 2007 in cs Lab., Department of Agronomy, Kyungpook National University, Korea to assess the effects of potassium nitrate on Gycine max (Var. Daewonkong) under ...

Lolium perenne has symbiosis relationships with an important group of endophytes genus Neotyphodium. Agronomic traits of this plant and its resistance to biotic and abiotic stresses are affected by Neotyphodium spp., resulting to changes in its physiology and morphology. Effect of Nickel and endophyte symbiosis on growth parameters and nickel uptake in two different natural populations are inve...

A greenhouse experiment with potted plants was conducted to study the effect of arbuscular mycorrhiza (Glomus intraradices) fungal inoculation on The growth, cadmium concentration and The activates of antioxidant enzymes (Superoxide Dismutase (SOD) and Catalase (CAT)) in sunflower and safflower in four levels of Cd (0, 2.5, 5 and 25 mg Cd kg-1 soil). Treatment were arranged in the experiment fa...

Greenhouse experiments in a completely randomized design were carried out to investigate the effects of nitroxin fertilizer (0, 1 and 2 li/ha) on morphological and physiological traits of Amaranthus retroflexus in 2013. The traits in the study included plant height, fresh and dry weight of shoots, roots, stem and leaf, Chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, anthocyanin, a...
