Effects of Water Deficit Stress and Two Mycorrhiza Species on Some Physiological Attributes and Tuber Fresh Weight of Potato cv. Agria Under Field Condition
In order to evaluate the tuber fresh weight and some physiological attributes of Agria potato cultivar in response to water deficit stress and mycorrhiza inoculation, a field trial was conducted as a split plot scheme based on randomized complete block design with three replications at the research site of Islamic Azad University, Tabriz Branch in 2012. Four water levels including: irrigation a...
متن کاملNitrogen supply affects arbuscular mycorrhizal colonization of Artemisia vulgaris in a phosphate-polluted field site.
Root colonization by arbuscular mycorrhizal fungi (AMF) was investigated in industrially polluted grassland characterized by exceptionally high phosphorus levels (up to 120 g kg(-1) soil). Along a pollution-induced nitrogen gradient, soil and tissue element concentrations of Artemisia vulgaris plants and their mycorrhizal status were determined. Additionally, we compared mycorrhization rates an...
متن کاملDiversity of arbuscular mycorrhizal fungi in grassland spontaneously developed on area polluted by a fertilizer plant.
Mycorrhizal colonization and diversity of arbuscular mycorrhizal fungi (AMF) were analyzed in a calcareous grassland with residual phosphate contamination 10 years after the closure of a pollutant fertilizer plant in Thuringia (Germany). AMF were detected in 21 of 22 plant species analyzed. Mean mycorrhization levels reached up to 74.5% root length colonized. AMF diversity was analyzed based on...
متن کاملEffect of Arbuscular Mycorrhiza fungi application on distribution of phosphorus forms in rhizosphere soils of sunflower (Helianthus annuus L.)
Appropriate management of soil phosphorus (P) fertility in highly calcareous soils of Iran as around the world should rely upon sound knowledge about the phosphorus reserve and its bioavailability. Despite numerous reports on the positive effects of vesicular arbuscular mycorrhizae (VAM) fungi on phosphorus uptake which is associated to Ectomycorrhiza as a branch of two major branches of group ...
متن کاملInteraction Effect of Arbuscular Mycorrhiza and Redroot Pigweed (Amaranthus retroflexus L.) on Growth and Yield of Sunflower under Water Stress Conditions
The management of soil elements by biological fertilizers is considered as an important attribute of sustainable agriculture. In order to evaluate the interaction effects of Arbuscular mycorrhizal fungi and redroot pigweed (Amaranthus retroflexus L.) on growth and yield of sunflower (Helianthus annuus L.) under water stress conditions, a field study was conducted in 2015 at School of Agricultur...
