Studia nad grzybami fitopatogenicznymi z Pienin
AbstractThe subject of the work was a comprehensive study of microscopic parasitic fungi of culture and wild plants, and an attempt at the determination of the role played by them in natural plant communities as well as of their influence on plant production in the investigated areas. In the area of the Pieniny Mts the total of 558 parasitic fungi was noted on about 856 host plants. Among the collected fungi 42 species proved new to mvcoflora of Pland /they are marked with an asterisk in the list/. 25 fungus species were for the first time found in Poland on the given host plants /marked with an asterisk/, a number of species being rare in our or even in the European mycoflora. Tables 1 and 2 show number of species of fungi from various taxonomic groups, numbers of their host plants and a quantitative comparison of mycoflora of the Pieniny region with other regions of Poland. Detailed data on the stations where the fungi were collected in the Pieniny Alta, notes and figures of fungi new or rare in Poland, data on the ecology of some groups and even species of fungi, as well as references to these subjects were published in other works of the author [52, 60-65]. In the investigation of the share of parasitic fungi in natural plant communities particular attention was paid to the number of fungus species found in individual communities /Table 3/, the density of occurrence evaluated in percentages and rates of plant damages /Tables 4 and 5/ and the percentage share of the investigated groups of fungi /Peronoeporales, Erysiphales, Uredinales, urid Ustilaginales/ in individual communities /fig. 2/; the number of collected species of fungi was compared with the number of possible host plants in a given community /fig. 3/, while the fungi occurring in a given community only were of special concern as well as the similarity of mvcoflora in the individual plant communities. Another subject of the study was the occurrence of parasitic fungi from the Pieniny Mts in Poland against the background of the distribution of their host plants. On the basis of D u r r i e u work , herbaria data from the literature on the occurrence of parasitic fungi and their plants in Poland, the fungi from the Pieniny Mts were analysed and classified to four groups of parasites: homotopes, amphitopes, oligotopes, and mejotopes. The four best known groups of fungi were taken into consideration in this classification: Peronosporales, Erysiphales, Uredinales, and Ustilaginalee, maps of distribution in Poland being elaborated for the more interesing species of fungi /figs 5-40/. In the investigation on the fungus diseases of culture plants in the Pieniny Its the following groups were studied: cereals, root crops, vegetables, Papilionaceae, fruit trees, and small fruits. Detailed data on this matter are given in separate works [67-70]. Particular attention is paid to species which play now or will soon play a decisive. role in the agricultural production of this region /Tables 9-12/. The obtained results, connected with data on other diseases and pests damaging crops in this area, and with data on soil, climatic, and economic conditions, may be useful in elaborating the optimal production directions of the Pieniny region. Some suggestions are also given for improving the state of health of agricultural crops in this area. Since the investigations and observations show papilionaceous fodder crops as the best and most healthy cultures here, this suggesting that they should prevail in this region, the management and utilization of montane meados was also discussed in the work. An experiment was carried out in order to investigate the effect of mineral fertilization and date of hay-making on the occurrence of parasitic fungi and damages to meadow grasses caused by them . It was found that suitable fertilization and management of montane meadows improved the state and laved dates of hay-making increased the number of occurring fungi and damages caused by them. It was also abserved that the nmicoflora of montane meadows distinctly differed from lowland grass-lands with regard to the number of parasitic fungi and the share of individual groups of parasites [66, 90]. A dam reservoir being constructed in the River Dunajec in the Pieninv Mts, it will be possible to compare the results obtained in this study with observations made after the reservoir was used for some years, and to show the directions of changes going on in the condition of plants proving in natural communities and in fields. These data may be useful in the solution of other scientific and economic problems.
