摘要

The influence of saprotrophic soil fungi: Aspergillus versicolor, Penicillium frequentans, Penicillium verrucosum var. cyclopium, and Trichocladium asperum on development, wholesomeness, gas exchange and yield of potato cv. Mila was studied in pot experiments during 1998–2000. The presence of each of the mentioned fungi species in soil accelerated potato germination and stimulated growth of overground plant parts in comparison with control plants. Additionally, the presence of the tested saprotrophes in soil prologed the potato growing period by inhibiting chloroses of necroses. The tested saprotrophic fungi also modified plant physiological processes, such as transpiration and assimilation. The contact of plant root system with soil saprotrophes diminished significantly assimilation and transpiration intensity of overground parts in comparison with the control plants, in all the years of the experiment. However, this response did not reduce the yield of tubers.
