摘要:

Grain sorghum plants were grown in nutritive solution culture under variable potassium concentrations from 0.5 to 6.0 meq/l, Na replacing ? in deficient solutions. The effect of potassium concentration in the nutrient medium on the organic acids content of leaves has been investigated. In sorghum leaves, aconitic, malic, citric, succinic acids are the most important (as evidenced by gas chromatography analysis).
