Four soil fungi were isolated from the soil by serial dilution and were identified as Aspergillus flavus Link, A. fumigatus Fresenius, A. niger van Tieghem and Trichoderma viride Pers. The soil fungi were selected to evaluate their antagonistic potential against seed borne fungus Fusarium merismoides isolated from sesame. In dual culture colony interaction Trichoderma viride showed the highest (45.88%) growth inhibiting effect on F. merismoides followed by A. niger (40.00%), A. flavus (36.37) and A. fumigatus (30.77%). Volatile metabolites from T. viride showed the highest growth inhibiting effect on F. merismoides (67.69%) and non-volatile metabolites from T. viride showed the highest growth inhibiting effect on F. merismoides (75.00%).

Filamentous fungi relatively easily disperse and colonize a variety of substrates, inhabiting various, often extreme environments. Therefore, they spread all over the world. The purpose of the research was to determine whether the propagules of filamentous fungi brought (accidentally transported) into the Antarctic biome by tourists and members of scientific expeditions are capable of developing at low temperatures. In the studies were used seven isolates of fungi: Penicillium sp., Aspergillus flavus, Alternaria alternata, Cladosporium cladosporioides, Trichoderma viride, Geotrichum candidum and Botrytis cinerea. The isolates came from samples collected from tourists and members of scientific expeditions arriving at the Henryk Arctowski Polish Antarctic Station on King George Island in the South Shetland archipelago. Fungal growth was measured at 0, 5, 10, 22°C (as a control) and 10° C, but after having frozen inoculum at -15°C for a period of 7 days. Penicillium sp., Alternaria alternata, Cladosporium cladosporioides, Trichoderma viride, Geotrichum candidum and Botrytis cinerea were found to be capable of growing at low temperatures (5 and 10oC as well as after one freezing cycle, down to -15oC and thawing, up to +10oC). They did not produce a macroscopically visible mycelium at temp. 0oC, however, it was not a lethal temperature for them, as when they were transferred to higher temperatures, they continued to develop even after a fairly long time following the beginning of the experiment. The most vulnerable was Aspergillus flavus. At lower temperatures (from about to 5oC) it did not develop, while freezing and thawing were lethal for this species. Some species (G. candidum, T. viride and B. cinerea), despite the development of mycelium, did not produce spores at lower temperatures.

A total of nine species of fungi were found to be associated with seeds of nine varieties of chickpea. The isolated fungi were Alternaria alternata, Aspergillus flavus, A. niger, A. fumigatus, A. nidulans, Curvularia lunata, Penicillium sp., Rhizopus stolonifer and Trichoderma viride. Association of fungi with chickpea seeds was recorded three times, within a week after harvest, after two and five months of storage. The fungal association varied with duration of storage period. Species of Aspergillus, Penicillium and Rhizopus become predominating fungi with increase of the storage period. The fungal association with seeds of chickpea also affects germination, seedling mortality and seedling height. Germination of BARI chola 6 and 7 were completely inhibited due to prevalence of Rhizopus stolonifer in the seeds examined within seven days of harvest. The total fungal infection in chickpea seeds was highest in BARI chola 8 (168) and lowest in BARI chola 1 (65).Journal of Bangladesh Academy of Sciences, Vol. 40, No. 1, 37-44, 2016
