Abstract

A search for allelochemical products of higher (vascular) plants in Hungary was conducted during 1988-94. Some 438 plant species were tested. Some new allelopathic species not previously mentioned in the literature were noted. These were Abutilon indicum, Allium cepa, A. flavum, Aristolochia clematitis, Artemisia alba, A. pontica, Betonica [Stachys] officinalis, Caltha palustris, Carlina acaulis, C. vulgaris, Centaurea arenaria, C. diffusa, C. jacea, C. micranthos, C. montana, C. nigra, C. nigrescens, C. sadleriana, C. pannonica, Chenopodium hybridum, Chrysanthemum vulgare, Cucurbita pepo, Digitaria ciliaris, Ecballium elaterium, Euphorbia lathyris, E. virgata, Genista tinctoria subsp. elatior, Heracleum mantegazzianum, Melampyrum nemorosum, Mentha aquatica, M. arvensis, M. longifolia, M. pulegium, M. × piperita, M. rotundifolia, M. × verticillata, Nepeta pannonica, Oxalis corniculata f. atropurpurea, Pastinaca sativa subsp. pratensis, Peucedanum cervaria, Prunella grandiflora, P. laciniata, P. vulgaris, Ranunculus acris, R. arvensis, R. auricomus, R. bulbosus, R. flammula, R. pedatus, R. polyanthemos, R. polyphyllus, R. repens, R. sardous, Sarothamnus scoparius [Cytisus scoparius], Spartium junceum, Suaeda maritima, Stachys annua, S. bizanthina, S. germanica and Telekia speciosa. The crude acetone extracts from the donor plants are suitable for direct practical application (mainly in small scale farming) in 40- to 200-ml/12.5 m2 doses.
