Einfluß von Lipidfraktionen mikrobieller Herkunft auf die Wasserausnutzung in der biologissechen Stoffproduktion von Kulturpflanzen

Effects of exogenous applied lipids being of microbial origin on the water use efficiency (WUE) and the biomass production have been studied in pot and field experiments using crop plants. Lipid mixtures extracted from the cells of Candida maltosa EH 15 increased the WUE (9…16%) and the grain yield (÷x = 10%) of the wheat and barley plants under dry conditions. The fatty acid fraction separated from the lipid mixtures also improved the WUE especially under stress (20…100%) and the biomass production. The phosphatide fraction emulsified with sulfonate containing solvents was not physiologically active.
