Opis:: The study was conducted in 2006 – 2008 at the Production and Experimental Station of the University of Warmia and Mazury in Olsztyn, located in Bałcyny (NE Poland). The objective of this study was to determine the microbial quality of soil after Brassicaceae grown as forecrops for winter wheat. A field experiment was established on grey-brown podsolic soil, and it involved the following forecrops: winter rapeseed, spring rapeseed, white mustard, Chinese mustard, and winter wheat as control. Soil samples for microbiological analyses were collected in the spring, before the sowing of forecrops, and in the autumn, after the harvest of Brassicaceae and ploughing-in crop residues. Bacterial and fungal communities isolated from soil sown with Brassicaceae as forecrops were generally more abundant and diverse. These communities exerted an inhibitory effect on the growth of soil pathogens. Forecrops with the greatest microbiological potential were white mustard and winter rapeseed.

Opis:: This study evaluated the development of above and under ground parts of strawberry plants cvs. 'Fern' and 'Camarosa1 in a glasshouse using perlite, forest soil, finpeat, peat, finpeat+perlite (1:1) and peat+perlite (1:1) as substrates. The effects of different growing media on development of above and under ground parts of plant were statistically significant. The highest number of primary roots per plant, length of the most developed roots and number of crowns per runner were obtained from perlite, finpeat+perlite and peat medium, respectively, in both cultivars. The runner length, number of runners per plant, leaf area, fresh root weight and dry root weight varied between cultivars according to growth medium. In general peat, finpeat or finpeat+perlite gave the best results in terms of above and under ground parts of plants in both cultivars. Some important properties such as water retention capacity, cation exchangeable capacity, pH, porosity etc. of growing media using in this study were also determined.

Tytuł:: Influence of mycorrhizal fungi on the growth and development of sandy everlasting Helichrysum arenarium (L.) Moench

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.

Tytuł:: Using the results of a nationwide phenological network to examine the impact of changes in phenology of plant species on the concentration of plant pollen in the air

Opis:: The application of phenological data together with meteorological and pollen data in a comprehensive analysis gives an opportunity to draw conclusions on variability of the starting date of the pollen season and its dynamics in terms of meteorological factors. It is quite important especially due to the fact that studies conducted all over Europe have proved that species phenology responds to climate warming trends. There has been observed a tendency to an earlier onset of spring flowering and leafing as well as the lengthening of the growing season. Although phenological network studies differ with regard to regions, species, events observed and applied methods, their data show a clear temperature-driven extension of the growing season by up to 2 weeks in the second half of the 20th century in mid- and high northern latitudes; for example, in Germany changes in timing of phenological spring events have been estimated at about -1.6 days / decade, while in Switzerland: -2.3 days / decade. Despite interannual variability in flowering date, caused by specific meteorological conditions each year, long-time series of phenological data from the area of Poland have proved that hazel flowering occurred in the surroundings of Warsaw later in the 50’s (third decade of March) than it is observed at the beginning of the 21st century (second decade of March). There is a lack of such long time series of pollen data, but we can suspect that the hazel pollen season has changed similarly to the time pattern of its flowering. Plants are very sensitive to weather conditions, therefore it is important to know as precisely as possible the impact of meteorological conditions on a plant’s reactions. The determination of thermal thresholds for a specific plant’s reactions may be beneficial for this purpose. The estimated value of Positive Degree Days (PDD> 50), which caused the first Corylus flowers (F2 phenophase) to bloom in the study years, requires testing in future years to make the threshold values credible.
