摘要：

Citric acid exudation and root growth under phosphorus-deficient condition were studied of the seedlings of maize grown in solution culture and rhizobox. Phosphorus deficiency resulted to increase citric acid excretion from P-deficient maize roots with concomitant decrease in pH of growth medium. The length of primary, lateral, total roots, roots hairs and number of lateral roots as well as roots hairs and root meristem volume increased of P-deficient maize seedlings.
