More than 20 years ago David Read highlighted the ideal relationship between dominant vegetation and plant mycorrhizal types; he divided world into major biomes hypothesized that symbioses modulate biome dynamics through soil-nutrient processes (Read, 1991). This idea has been accepted further developed theoretically in northern hemisphere (Read & Perez-Moreno, 2003), but conversely, no clear development made southern hemisphere, particular South America, despite its contrasting patterns of...
Tomato is widely consumed throughout the world for its flavor and nutritional value. This functional food largely depends on implementation of new strategies to maintain nutraceutical value, e.g. lycopene concentration, overcome challenges sustainable production security. The use arbuscular mycorrhizal fungi (AMF)-based biostimulants represents one most promising tools management agricultural soils, being fundamental organic production, reducing fertilizers pesticides use, decreasing...
Southern Chilean pristine temperate rainforests have been floristically stable during the Holocene, thus representing a pre-industrial baseline of forest ecology.Given this and its edaphic limitations, it is imperative to better understand these forests ecological patterns mycorrhizal symbiosis.Therefore, here we compare arbuscular (AM) communities in three treeline Nothofagus pumilio contrasting plots Andes (a volcano crater, forest, disturbed forest).The AM community assemblages were...
New evidence has shown that arbuscular mycorrhizal (AM) fungi can contribute to the aluminum (Al3+ ) tolerance of host plants growing in acidic soils with phytotoxic levels Al3+ . The aim this study was investigate role AM isolated from naturally occurring conferring toxicity three wheat cultivars differing sensitivity. experiment conducted a soilless substrate (vermiculite/perlite, 2:1 v/v) using two -tolerant genotypes and one -sensitive genotype. colonized consortium an Andisol, or...
Arbuscular mycorrhizal fungi (AMF) have an important role on the ecosystem stability promoting water and nutrient acquisition by plants allowing their growth under stress conditions including drought salinity.This study aimed at describing colonization of native AMF associated to pioneer plant species growing mouth lake Budi, which receive seasonally marine water.For this, root samples rhizosphere substrate Polygonum maritimum, Carpobrotus chilensis, Ambrosia chamissonis, Ammophyla arenaria...
The aim of this work was to establish the effect dose liquid cow manure (LCM) on some chemical properties and biological activity in an Andisol.This study carried out under laboratory conditions using Andisol LCM from a dairy farm located South Chile.The were equivalent 0 (S0), 100 (S100), 200, (S200) 300 (S300) thousand L ha -1 .This amount is regular agronomic applications.The characterization indicated that addition modified all tested properties.These begin return initial 10 days on,...
Intercropping is especially relevant for low-income farmers when crop production developed in soils under the new scenario produced by climatic change, mainly water shortage and low availability of nutrients P. An example this would happen volcanic Southern Chile with high P fixing capacity where most cereals are cropped. The aim study was to compare benefits obtained on soil biochemical properties wheat (Triticum aestivum L.) growth sowed monoculture or intercropped non-mycorrhizal plants...
Conventional tillage (CT) is a soil management system commonly used by small farmers in the Ecuadorian highlands; they remove during seedbed preparation to eliminate weeds, improve aeration, avoid compaction, and develop adequate rooting space.CT causes changes physical, chemical, biological properties but, long run, have negative effects on crop performance.Most of these can be avoided using no-tillage (NT).The objective this study was determine initial NT, different fertilization rates...
