Popis:	Crop production in acid soils may be limited by several factors, including low pH. Development of acid-tolerant cultivars requires information about differences in tolerance to low pH among crop genotypes. To determine whether differential responses to nutrient solution pH ocurred among seven maize (Zea mys L.) genotypes, seedlings wee grown in a growth chamber in flowing solutions at pH levels ranging from 3.3 to 6.7. Top weights, root lengths and weights, and concentrations of Ca, Mg, Fe, Zn, and Mn in plant tops were determined after 12 d (...)
