Abstract:
Many biotope types on Austria´s agricultural land have come under pressure due to land abandonment and especially due to intensification of agricultural use. In particular grassland habitats show a considerable reduction of floristic diversity as a result of higher fertilization intensities and higher utilisation frequency. The active cultivation of floristically valuable grasslands with certified wild plant seeds could be one way to counteract this trend. In order to produce seeds of wild plant species, the propagation plant stands have to be cultivated free from weeds and other disruptive factors. In this thesis, a series of experiments was conducted to find out if the cultivation of wild plant seedlings helps to reach the requirements. For this purpose, six different wild plant species were examined for the impact of cultivation substrate, growing chamber and cooling and seeding date on germination progress, number of seedlings, usable plants as well as above-ground and below-ground biomass. We found out, that the different treatment variations had a different effect on the wild plant species studied. Some types showed a significant effect of treatments, for example, cooling had a considerable positive influence on the development of Shining meadow rue (Thalictrum lucidum). For other species like Crested hairgrass (Koeleria macrantha), however, no striking differences in the results occurred. For each of the six species, a specific recommendation on how best to produce seedlings was developed. From all the results and findings that occurred in the course of the series of experiments, a general approach for the seedling cultivation of wild plants was also worked out. This is based on the previously known data and on the characteristics of the wild plant species and is intended to provide a guidance for successful seedling production.
