NOVOTNÝ D., LUKÁŠ J., BROŽOVÁ J., RŮŽIČKOVÁ P. (2019): Comparison of the occurrence of fungi causing postharvest diseases of apples grown in organic and integrated production systems in orchards in the Czech Republic. [Malus domestica, organic production, integrated production, Neofabraea, Penicillium.] Czech Mycology 71(1): 99-121 (published: 28th June, 2019)
abstract
During the years 2013–2015, the occurrence of fungi causing postharvest diseases of apples was evaluated in three apple orchards with integrated and organic production systems in the Czech Republic. The postharvest disease fungi were more frequently recorded in fruits from organically cultivated apple trees (average 29.97%) than those from integrated production (17.67%). This difference is statistically significant. Neofabraea, Penicillium, Alternaria and a sterile grey mycelium were the most frequently recorded taxa in apples grown in organic and integrated production systems. There were also significant differences in the frequency of occurrence of the most frequent fungal taxa between years. In 2013 and 2014, Neofabraea was the most frequently isolated genus in both cultivation systems, whereas in 2015, Penicillium was the most frequently recorded genus also in both cultivation systems, which was likely caused by the low precipitation in the 2015 growing season.
HÝSEK J., BROŽOVÁ J. (2001): The role of some saprophytic micromycetes and fungus Micromucor ramannianus var. ramannianus in forest soil. [humic horizon, soil fungi, saprophytic micromycetes, Micromucorramannianusvar. ramannianus, biological soil functions, respiration, ammonification, nitrification] Czech Mycology 53(2): 161-171 (published: 20th February, 2002)
abstract
Different saprophytic micromycetes were isolated from the humic horizon (H-A 02) of different types of forest soils (barren l and of reforested waste dumps, cambisol of spruce, birch, European mountain ash, and blue spruce forests) in several areas (at Most in the Krušné hory (Ore Mts.), Jizerské hory (Izera Mts.)). Besides the spectrum of common species of soil micromycetes (Penicillium spp., Humicola spp., Trichoderma spp., Paecilomyces spp., Scopulariopsis spp., Aureobasidium spp., Mucor spp., Absidia spp.), the fungus Micromucor ramannianus (Möller) Arx var. ramannianus (Mortierella ramanniana (Möller) Linneman, Mucor ramannianus Möller) was regularly isolated from all types of soils, except barren soils of was te dumps. The biological quality of forest soils in connection with other biological characteristics was evaluated in relation to the presence and quantity of this fungus in forest soils. Basic biological processes (basal and potential respiration, ammonification, nitrification) show an increased intensity in forest soils in which the proportion of Micromucorramannianus v. ramannianus was not present in the soil of the worst biological quality (lower values of biological soil parameters), e.g. in of was te dumps. It is a topic for discussion whe the r this fungus can also be an indicator of environmental pollution.
