Název v původním jazyce

Organic compounds in root exudates of miscanthus x giganteus greef et deu and limitation of microorganisms in its rhizosphere by nutrients.

Popis výsledku v původním jazyce

The aim of this work is determine composition of sugars and organic acids in root exudates of Miscanthus x Giganteus and to determine if respiration of soil taken from rhizosphere of this plant was limited by mineral nutrients. Root exudates of this plant were collected in 0.5 mM CaCl2 from differently aged plants and contained two sugars including glucose and saccharose (measured in older plants at the end of summer period of growth) and several organic acids (measured in 27 days old plants) ranging inthe order succinic > propionic > citric > tartaric > malic > oxalic > ascorbic > acetic > fumaric. Respiration of microorganisms in the rhizosphere of Miscanthus x Giganteus was limited by mineral nutrients including nitrate, ammonium, calcium and potassium. The increase in respiration rate after application of these mineral compounds in the highest amount (500 micrograms / g dry soil) appeared in the order nitrate > calcium > potassium > ammonium, giving approx. 16
