Abstract
The effects of various cellulose treatments on the hydrophobic properties and sorption behavior with respect to liquid water uptake and water vapor sorption were examined within the study. Different hydrophobic agents based on silicon compounds were applied to improve the properties of cellulose-based sheets. The 1H,1H,2H,2H perfluorooctyltriethoxysilane treatment increased hydrophobicity significantly, while N-octyltriethoxysilane and inorganic sodium silicate solution treatments only slightly affected the properties. Silicone-cellulose interaction varied, influencing the fiber saturation and moisture content of the material. The swelling differences between untreated and treated cellulose and, consequently, the uncovering of new active sorption sites during a swelling process and the increase in the content of bound water were confirmed by the T2 relaxation times analysis. The GDW sorption model estimated maximum water content but lacked activation dynamics. The blocking phenomenon of active sorption sites together with silicone improved hydrophobicity had different mechanisms for applied agents. The 1H,1H,2H,2H perfluorooctyltriethoxysilane additionally cross-linked silane structure and restricted cellulose swelling.

Abstract
With rising temperatures and shifting rainfall patterns driven by climate change, conditions for pathogen-plant interactions will be affected based on the specific pathogen and plant species involved. In general, increased pathogen activity is expected in Norwegian grasslands. Recent breeding efforts in Norway have concentrated primarily on developing varieties resistant to fungal diseases that cause winter damage. However, their resistance against other diseases may fall short, as they have not been targeted in the Norwegian breeding programme. As a result, a comprehensive evaluation of the current situation is essential. This ongoing project aims to identify foliar fungal species and disease distribution in breeding lines and varieties of four prominent meadow species: timothy, perennial ryegrass, meadow fescue and red clover. The study encompasses four locations in Norway, spanning from 60 to 69° N. Observations from the first season indicated relatively good resistance to both winter and growing season-related fungi in the investigated breeding material of timothy. The observations indicated that perennial ryegrass is more susceptible to winter diseases, whereas its resistance to growing-season diseases is relatively good. Conversely, meadow fescue and red clover displayed moderate susceptibility to fungal diseases during the growing season but demonstrated commendable resistance to overwintering fungi.
