Changes in catalase (CAT) activity and in CAT isoform pattern and expression were investigated in developing sunflower (Helianthus annuus L.) seeds during desiccation on the mother plant and after artificial drying on the flowerheads. Seeds regularly desiccated during their development on the mother plant and reached mass maturity at c. 42 d after flowering (DAF). Freshly harvested seeds did no...

HE study reported in this paper concerns the effects of X-rays and thermal neuT trons on dormant seeds of the tomato, Lycopersicon esculentum, expressed as chromosomal abnormalities in root tip mitoses, seedling injury, and chlorophyll and morphological changes. XI and NI refer to the X-rayand thermal neutron-irradiated generations, respectively; Xz and Nz to the progenies of the XI and NI gene...

Invasive plant species threaten native and habitats causing ecologic, economic social burden. When creating climate friendly solutions by utilizing biomasses in biogas fertilizer production, safety should be ensured concerning the use of residues. This study concentrates on treatment containing invasive material tunnel windrow composting, farm-scale laboratory-scale anaerobic digestion (AD) mes...
