BIOLOGICAL ASPECTS OF SEEDS IN THE PRODUCTION OF MEDICINAL AND AROMATIC PLANTS
While, at present, most of the food for human nutrition is supplied by hardly more than 20 major crops, the number of seeds utilized for their medicinal or aromatic properties is also significant. Table 1 provides a list of some major commercially available seeds and fruits
At the XXII.nd International Horticultural Congress Tétényi (1982) gave a comprehensive survey of the "Biological preconditions of Aromatic and medicinal plant cultivation". Farther reviews on the topics have been made by Balbaa (1982), Bernáth (1985), Máthé (1988), Palevitch (1987). Referring to the above mentioned, on this ocassion we focus our attention on the biological aspects of seeds in species grown for their seed-yield. Our main aim is to draw attention to the multiplicity of factors influencing the production of these species. Owing to the most complex character of the topics, this can only be done without the intention to be complete.
