The residue of peas (Pisum sativum L.) has allelopathic activity and the putative compound causing this inhibitory effect was isolated from a methanol extract of pea shoots. Chemical structure of this compound was determined by high-resolution MS, IR and 1H NMR spectral data as pisatin. Pisatin inhibited growth of cress (Lepidium sativum L.) and lettuce (Lactuca sativa L.) seedlings at concentrations greater than 10 and 30 microM, respectively. The doses required for 50% growth inhibition of… CONTINUE READING
