Koreninski izločki zelja in čebule bolj ali manj zavirajo rast antagonističnih gliv (Trichoderma spp., Gliocladium roseum), izločki koruze in graha pa rast nekaterih stimulirajo. Metaboliti T. koningii  negativno vplivajo na kalitev semen čebule, radiča in solate. Špinača hitreje kali, če dodamo filtrate T. longibrachiatum, T. harzianum  in T. viride. Filtrata T. longibrachiatum in T. harzianum  pospešujeta kalitev rdeče pese in paradižnika oz. paradižnika in radiča. Filtrati gliv vplivajo samo na hitrost kalitve, ne pa tudi na končno kalivost.

ABSTRACT

ALLELOPATHY BETWEEN ANTAGONISTIC FUNGI AND HIGHER PLANTS

The root excretions of cabbage and onion have a more or less pronounced inhibitory effect on the growth of antagonistic fungi (Trichoderma spp., Gliocladium roseum), while root excretions of maize and pea stimulate the growth of some antagonists. Metabolites of T. koningii have a negative effect on germination of the onion, chicory and lettuce seeds. The germination of spinach seeds is enhanced if filtrates of T. longibrachiatum, T. harzianum  and T. viride are added to the medium. Filtrates of T. longibrachiatum in T. harzianum enhance the germination of red beet and tomato resp. tomato and chicory. Generally speaking, the filtrates of fungi influence only the germination rate and have no effect on the final germination.
