Quercus robur seedlings are very often infested by oak powdery mildew caused by Erysiphe alphitoides. This disease attacks primary leaves with high insolation. In our experiment seedling growth in different light conditions was observed. Seedlings were derived from intact seeds or from seeds where the distal ends of acorns were cut off. Acorns were sown in pots at four light conditions (2%, 8% and 30% light transmittance and in full sunlight). For half of the seedlings we reduced the influence of powdery mildew by using a fungicide. Height of seedlings, shoot dry mass and the degree of damage caused by Erysiphe alphitoides were measured. The highest damages were in full light conditions and the lowest in the 30% light treatment. The influence of acorn reduction on powdery mildew infection was not significant (p=0.0763), however, in the full light conditions the seedlings from cut acorns were ca. 30% less damaged. The cutting of acorns also alters the height of seedlings and shoot mass. The tallest seedlings were from cut seeds growing in the 30% light treatment. The influence of the fungicide was lowest in the 30% light treatment where the decrease in damage was only ca. 10%. For nursery practice we can say that oak seedling production from cut off acorns under 30% light transmittance should give the best results of seedling growth even without the fungicide application.

Mistletoe is semiparasite adversely affecting the functioning of their hosts especially at water management level. So far, there have been no reports about the impact of mistletoe on seeds from any host. The aim of the work was to evaluate the effect of the presence of mistletoe on the quality of the seeds of Scots pine (Pinus sylvestris). Unopened cones from infected and uninfected trees were collected in April 2015 in the Excluded Seed Stand in Bolewice Forest District (52°23‵54.347‵N; 16°05‵01.978‵E). Measurements of cones and seeds were made. Some seeds were used for pot experiment, where the seedlings were planted from May to October 2015. On the second part of the seeds in the end of July and August germination tests were made. The size and mass of the cones, the number and weight of seeds, and the height and weight of the seedlings were lower for the material collected from the mistletoe trees. The differences were not large but statistically significant (tabs. 1 and 2). The results showed that mistletoe has a negative impact on the parameters of cones, seedlings and seeds quality.
