Opis:: The plants of angelica Archangelica officinalis may be colonized by various species of fungi including Phoma species. The paper concerns the fungus Phoma complanata, isolated from above-ground and underground parts of angelica in 2009–2011. Pathogenicity tests according to Koch’s postulates were carried out on angelica plants using various methods of inoculation. Observations of the infection process were made using the scanning electron microscope (SEM). Three our own isoletes and reference isolate of P. complanata were used in the study. P. complanata was found to be a facultative pathogen of angelica, which enters to the plant through stomata and wounds without creating appressoria in the top part of the germination hyphae.
Arcydzięgiel litwor (Archangelica officinalis Hoffm.) może być zasiedlany przez różne gatunki grzybów, w tym również przez grzyby Phoma sensu lato. Przeprowadzone badania dotyczą gatunku Phoma complanata wyizolowanego z nadziemnych i podziemnych części arcydzięgla w latach 2009–2011. Testy patogeniczności przeprowadzono zgodnie z postulatami Kocha, z uwzględnieniem różnych metod inokulacji. Potwierdziły one patogeniczny charakter polskich izolatów P. complanata oraz izolatu referencyjnego dla wybranych organów arcydzięgla. Obserwacje przebiegu procesu infekcji wykonano przy użyciu skaningowego mikroskopu elektronowego (SEM). Na podstawie przeprowadzonych badań P. complanata uznano za fakultatywny patogen arcydzięgla. Grzyb wnika do tkanek przez aparaty szparkowe bez tworzenia na końcu strzępki kiełkowej struktury adhezyjnej w postaci appresorium.

Opis:: The significance of root colonization by mycorrhizal fungi for the growth and development of Helichrysum arenarium was investigated in two independent experiments. In the first experiment the association of root colonization level with the pluviothermal conditions within the growing season and the age of a natural plant population was analyzed. In the second one, under controlled conditions, the influence of artificial inoculation with the arbuscular fungus Glomus intraradices on the features of plants raised from achenes was studied. It was shown that hydrothermal conditions during blooming period had a greater influence on reproduction processes of sandy everlasting than both the population age (the secondary succession progress) and the level of root colonization by mycorrhizal fungi. High amount of precipitation at plant generative development phase positively influences the potential and actual fertility of ramets. The presence of arbuscular fungus in the soil favors the growth and development of sandy everlasting specimens at their early growing stages: they have a better-developed root system and a greater photosynthetic area.
W dwóch niezależnych eksperymentach poddano ocenie znaczenie kolonizacji korzeni Helichrysum arenarium przez grzyby mikoryzowe, dla wzrostu i rozwoju roślin. W pierwszym doświadczeniu badano powiązanie stopnia kolonizacji korzeni z warunkami pluwiotermicznymi okresu wegetacji i wiekiem naturalnej populacji rośliny. W drugim doświadczeniu, w warunkach kontrolowanych, analizowano wpływ sztucznej inokulacji grzybem arbuskularnym Glomus intraradices na cechy roślin pozyskanych z siewu niełupek. Wykazano, że warunki termiczno-wodne w okresie kwitnienia kocanek piaskowych mają większy wpływ na procesy reprodukcyjne niż wiek populacji (zaawansowanie sukcesji wtórnej) oraz stopień ich kolonizacji przez grzyby mikoryzowe. Duża ilość opadów w okresie rozwoju generatywnego roślin korzystnie wpływa na płodność potencjalną i rzeczywistą ramet. Obecność w podłożu grzyba arbuskularnego sprzyja wzrostowi i rozwojowi kocanek piaskowych we wczesnych stadiach rozwojowych – mają one lepiej wykształcony system korzeniowy i większą powierzchnię asymilacyjną.

Opis:: Fungal entomopathogens can naturally regulate populations of various insects. The entomopathogen Beauveria bassiana (Bals.- Criv.) Vuill. is also able to endophytically colonize different plants. Endophytic colonization by entomopathogens may provide a source of indirect interactions between fungi and insects and has been associated with the ability of the fungus to control insect pests. The tomato leaf miner, Tuta absoluta (Meyrick) is considered one of the most devastating pests of tomato (Solanum lycopersicum L.) and its difficult control is due to its miner habit, short life cycle, and high reproductive capacity. The aims of this study were: (i) to use three different techniques, i.e. leaf spraying, seed immersion and root dipping, for the endophytic inoculation of B. bassiana in tomato plants; and (ii) to assess the effect of B. bassiana on tomato leaf consumption and mortality of T. absoluta after inoculation. The percentage of colonization by B. bassiana was assessed 7, 14 and 28 days after inoculation. All inoculation techniques employed allowed the recovery of B. bassiana, although our results showed significant differences between techniques. Leaf spraying was the most effective, with the highest percentage of colonization recorded 7 days after inoculation. We also evaluated (i) the effect on the mortality of T. absoluta by direct contact with conidia of B. bassiana, and (ii) the effect on tomato leaf consumption and mortality by indirect contact through ingestion of inoculated plant tissues with B. bassiana. Mortality bioassays showed that B. bassiana infected T. absoluta, either by direct contact or indirectly, via ingestion of inoculated tomato leaves. Direct contact showed a higher percentage of mortality and a lower median survival time (MST) than indirect contact. Significant differences in the mortality percentages of T. absoluta after exposure with B. bassiana were found among the treatments and the control. Our results suggest that the endophytic inoculation of B. bassiana in tomato crops provides the basis for further investigation, which should focus on the virulence of the endophytic B. bassiana against T. absoluta.

Opis:: Arbuscular mycorrizal (AM) fungi may enhance plant growth and polyphenol production, however, there have been limited studies on the relationships between root colonization of different fungal species and polyphenol production on cultivated Allium porrum (garden leek). The effects of inoculation of AM fungi spores from Rhizophagus intraradices, Giga -spora margarita, Glomus geosporum, Paraglomus occultum, Claroideoglomus claroideum, and Glomus species on colonization of garden leek roots and symbiotic changes in polyphenol production and plant growth were evaluated in greenhouse experiments. There were significant differences (p < 0.05) in colonization of leek roots by AM fungi species. The greatest level of root colonization was recorded on plants inoculated with R. intraradices (73%) and the lowest level on C. claroideum (3.2%). Significant differences (p < 0.05) in plant height were recorded between AM inoculated plants and the controls. Polyphenol levels differed significantly (p < 0.05) between garden leek plants inoculated with AM fungi and the non-inoculated controls. The percentage increases in polyphenol (a derivative of kaempferol) on garden leeks inoculated with G. geosporum relative to the untreated controls ranged from 28 to 1123%. Due to symbiosis with different AM species, other polyphenols decreased in some instances (negative values) and increased in others for values of up to 590%. Results showed that AM fungi species exhibited remarkable differences in polyphenol levels in garden leeks. The high polyphenol production by garden leek plants inoculated with G. geosporum, and Glomus species could be exploited for enhanced resistance of garden leeks to insects and diseases. This research highlights an understudied area, notably the relationships between AM fungal inoculations, root colonizations and polyphenol production in garden leeks. The findings can be utilized to improve pest resistance and the quality of garden leek plants.

Opis:: Biofertilizers have been used as sources to improve plant nutrients in sustainable agriculture. Biofertilizers are low cost, renewable sources of plant nutrients which supplement chemical fertilizers. Mycorrhizal fungi are a major component of agricultural natural resources and members of kingdom fungi. The term ‘mycorrhiza’ is derived from Greek word which means ‘fungus root’. Earthen pot experiments were carried out to study the inoculation effect of Arbuscular Mycorrhizal (AM) fungi (Glomus mossease), Azospirillium brasilense and PSB on plant height, dry weight of root and shoot, per cent root colonization, spore number, P and N uptake. Experimental pots were filled with 4 kegs of sterilized soil and maintained in green house at 25-30 °C temperature. Single inoculation of AM fungi and combined inoculation of AM fungi with Azospirillium brasilense or PSB was found to be moderately increased in all the growth parameters. However triple inoculation of AM fungi, Azospirillium brasilense and PSB was found to have highest growth parameters.
