ABSTRACT

Pumpkin (Cucurbita pepo L.) is one of the popular seasonal vegetables cultivated in the world under different climatic conditions. This crop is important as a vegetable and medicinal plant used as a component in the diet. The aim of the experiment was to estimate the biodiversity of fungi colonizing pumpkin plants cultivated in the field and determine the strength of the interaction in communities of fungi, by using the biotic activity test. The experiment was set up in the organic farm in Zezulin (Lublin province, Poland) where the pumpkin plants ‘Bambino’ were cultivated in 2010 and 2012. The leaves, stems and roots of pumpkin were collected for mycological analysis at the beginning of fructification (71 BBCH). Laboratory test showed that predominating fungi colonizing plants were Alternaria alternata, Fusarium culmorum, Giberella intricans, F. oxysporum and Tanatephorus cucumeris.



The biotic interactions between the most important species fungi such as A. alternata, F. culmorum, F. oxysporum and other fungal species were studied using the biotic series method. Trichoderma spp. were found as the most effective and positive antagonists against Alternaria alternata, F. oxysporum and F. culmorum. It was show that A. alternata and F. oxysporum were weak competitors because their growth was limited by numerous fungi such as Trichoderma hamatum, Tanatephorus cucumeris and other fungi used in the test. F. culmorum was strong competitor because it limited the growth of other fungi from phyllosphere of pumpkin plants, however its growth can be inhibited by a great number of Trichoderma spp. colonies.

Key words: biodiversity of fungi, squash, Alternaria alternata, Fusarium spp., Giberella spp., Trichoderma spp., biotic series method.
