Biological properties of alkaloids. Influence of quinolizidine alkaloids and gramine on the germination and development of powdery mildew,Erysiphe graminis f.sp.hordei

Short Communications


The quinolizidine alkaloids sparteine, lupanine and 13-tigloyl-oxylupanine and the indole alkaloid gramine inhibited the germination of conidia ofErysiphe graminis f.sp.hordei Marchal and also the further development to appressoria. Half-maximal inhibitory concentrations of these alkaloids were 1–5 mmol/l. This result provides further evidence for a role of alkaloids as chemical defense compounds in plants.

Key words
