Abstract Background Aluminium (Al) toxicity and drought stress are two major constraints for
crop production in the world, particularly in the tropics. The variation in rainfall distribution …

Physiological aspects of acidity stress in plants (synonymous with H+ rhizotoxicity or low-pH
stress) have long been a focus of research, in particular with respect to acidic soils where …

Root system architecture influences nutrient and water uptake efficiency and thus plant
growth and productivity. Root architecture traits conferring efficiency in capturing resources …

Abstract Background and Aims Aluminium is toxic in acid soils because the soluble Al3+
inhibits root growth. A mechanism of Al3+ tolerance discovered in many plant species …

Many of the soils in the Australian cereal belt have subsoils with chemical and physical
properties that restrict root growth, which limits water use and yield. On alkaline sodic soils …

Waterlogging results in high shoot concentrations of iron (Fe), aluminum (Al), and
manganese (Mn) in wheat grown in acidic soil. The verification of this observation in several …

Seven genotypes of soybean (Glycine max (L.) Merrill) were screened in 2004 and 2005
planting seasons at the experimental research farm of the University of Nigeria, Nsukka to …

A stay-green phenotype is useful for adaptation of wheat to end-of-season drought
conditions. We identified quantitative trait loci (QTL) for stay-green traits, as well as for …

Climate change is varying the availability of resources, soil physicochemical properties, and
rainfall events, which collectively determines soil physical and chemical properties. Soil …

Soil constraints limit crop water and nutrient extraction and lead to yield loss globally. In
rainfed agriculture, the selection of crop species more likely to yield well under constrained …
