Phenolic metabolites are frequently implicated in chemical defense mechanisms against
pathogens in woody plants. However, tree breeding programmes for resistance to …

Kernels of corn, Zea mays, were inoculated with Fusarium moniliforme to analyze seedling
growth and development during endophytic, symptomless infection. In planta F. moniliforme …

The bark anatomy of Norway spruce clones that were resistant or susceptible to Ceratocystis
polonica, a bark‐beetle‐vectored fungal pathogen, was compared. The major difference …

Norway spruce (Picea abies), Scots pine (Pinus sylvestris) and silver birch (Betula pendula)
are the major tree species grown in Finnish forest nurseries where 99% of the seedlings are …

Peroxidases are associated with the active defence reactions in higher plants in response to
foreign organisms. They are involved in the oxidation of phenolic compounds in cell walls …

Pre-penetration behavior of Boytryosphaeria dothidea on apple fruits was investigated with
scanning electron microscopy. Once conidia were deposited on the fruit surface, they …

We are studying the interaction between the roots of Norway spruce seedlings (Picea abies
L. Karst) and a highly pathogenic isolate of Pythium dimorphum. Here, we report the …

Pythium species are common damping-off pathogens that can cause stunting, chlorosis, and
death of conifer seedlings in the Pacific Northwest (PNW) region of the United States …

We report on the growth pattern of the root rot pathogen Phytophthora quercina in roots of
oak seedlings and on the localization of its elicitin quercinin. Some hours after infection, the …

We have studied the reaction of Picea abies seedlings to infection with Pythium. The highly
virulent species Pythium ultimum and the less virulent species Pythium irregulare …
