The aim of this study was to compare the virulence of the two Dothistroma species in natural infection experiments on 2-year-old seedlings of two DNB susceptible pine species, Pinus nigra and P. mugo, in two seedling stands for each pathogen species.

In this paper, we explored the reaction of Pinus mugo (P. mugo) to O3-induced stress in the continental climate of an ozone-rich mountain area in the High Tatra Mountains (Western Carpathians). The efects of O3 doses modelled by a deposition model, O3 concentrations and other factors on P. mugo were identifed from (a) satellite-based data via NDVI (normalised diferenced vegetation index) over 2000–2020 and (b) visible injury on needle samples gathered from P. mugo individuals at ground-truth sites in 2019 and 2020. Analysing the NDVI trend, we observed non-signifcant changes (p>0.05) in the greenness of P. mugo despite growing in an environment with the average seasonal O3 concentration around 51.6 ppbv, the maximum hourly concentrations more than 90 ppbv and increasing trend of O3 doses by 0.1 mmol m−2 PLA (plant leaf area) year−1. The visible O3 injury of samples collected at study sites was low (mean injury observed on 1–10% of needles’ surface), and the symptoms of injury caused by other biotic and abiotic factors prevailed over those caused by O3. In addition, the correlation analyses between NDVI and the climatic factors indicated a signifcant (p<0.05) and positive relationship with photosynthetic active radiation (R=0.45) in July, and with stomatal conductance (R=0.52) and temperature factor (R=0.43) in August. Therefore, we concluded that the positive efect of climate conditions, which support the growth processes of P. mugo, may suppress the negative efect of the mean O3 doses of 17.8 mmol m−2 PLA accumulated over the growing season.}, keywords = {}, pubstate = {published}, tppubtype = {article} } High altitudes have been exposed to enhanced levels of surface ozone (O3) concentrations over recent decades compared to the pre-industrial era.

The efects of O3 doses modelled by a deposition model, O3 concentrations and other factors on P. mugo were identifed from (a) satellite-based data via NDVI (normalised diferenced vegetation index) over 2000–2020 and (b) visible injury on needle samples gathered from P. mugo individuals at ground-truth sites in 2019 and 2020. Analysing the NDVI trend, we observed non-signifcant changes (p>0.05) in the greenness of P. mugo despite growing in an environment with the average seasonal O3 concentration around 51.6 ppbv, the maximum hourly concentrations more than 90 ppbv and increasing trend of O3 doses by 0.1 mmol m−2 PLA (plant leaf area) year−1. The visible O3 injury of samples collected at study sites was low (mean injury observed on 1–10% of needles’ surface), and the symptoms of injury caused by other biotic and abiotic factors prevailed over those caused by O3. In addition, the correlation analyses between NDVI and the climatic factors indicated a signifcant (p<0.05) and positive relationship with photosynthetic active radiation (R=0.45) in July, and with stomatal conductance (R=0.52) and temperature factor (R=0.43) in August. Therefore, we concluded that the positive efect of climate conditions, which support the growth processes of P. mugo, may suppress the negative efect of the mean O3 doses of 17.8 mmol m−2 PLA accumulated over the growing season. |

In 2014–2016, species richness and prevalence of entomopathogenic fungi were evaluated during the bark beetle outbreaks in spruce forests affected by windstorms in the Tatra National Park in Slovakia. Three Beauveria species, B. bassiana, B. caledonica and B. pseudobassiana, with Metapochonia bulbillosa were identified from 271 specimens of three bark beetle species, Ips typographus, Ips amitinus and Pityogenes chalcographus. Beauveria bassiana was the dominant pathogen and infected all three bark beetle species. Phylogenetic analysis identified three phylogenetic groups of B. bassiana in the evaluated host populations. M. bulbillosa was reported for the first time from bark beetle hosts and Slovakia. The prevalence of fungal infection in natural populations of I. typographus was low, varied between 0.07 and 0.72%, and have little influence on the bark beetle abundance. |

This pathogen is known in many pine-growing regions, including natural and planted forests, and can affect all life stages of trees, from emerging seedlings to mature trees. Despite the importance of PPC, the global distribution of F. circinatum is poorly documented, and this problem is also true of the hosts within countries that are affected. The aim of this study was to review the global distribution of F. circinatum, with a particular focus on Europe. We considered (1) the current and historical pathogen records, both positive and negative, based on confirmed reports from Europe and globally; (2) the genetic diversity and population structure of the pathogen; (3) the current distribution of PPC in Europe, comparing published models of predicted disease distribution; and (4) host susceptibility by reviewing literature and generating a comprehensive list of known hosts for the fungus.

This pathogen is known in many pine-growing regions, including natural and planted forests, and can affect all life stages of trees, from emerging seedlings to mature trees. Despite the importance of PPC, the global distribution of F. circinatum is poorly documented, and this problem is also true of the hosts within countries that are affected. The aim of this study was to review the global distribution of F. circinatum, with a particular focus on Europe. We considered (1) the current and historical pathogen records, both positive and negative, based on confirmed reports from Europe and globally; (2) the genetic diversity and population structure of the pathogen; (3) the current distribution of PPC in Europe, comparing published models of predicted disease distribution; and (4) host susceptibility by reviewing literature and generating a comprehensive list of known hosts for the fungus. These data were collated from 41 countries and used to compile a specially constructed geo-database (http://bit.do/phytoportal).

Although T. harzianum isolates significantly inhibited the growth of Phomopsis carposchiza, the mycelium growth of some of the re-isolates on fresh medium indicates an inadequate antagonistic effect of T. harzianum on this species. The tested Trichoderma isolates showed stronger antagonism towards the other pathogens, reflected in overgrowing of Phyllosticta sphaeropsoidea and Diaporthe padi and reducing their growth. Granulation of the cytoplasm and lysis of hyphae of the fungal pathogens were the most frequently observed effects of the interaction. |

Two-year-old chestnut seedlings of eight progenies, derived from open and controlled pollination of three hybrids (Castanea sativa × C. crenata and a C. crenata tree by paternal tree of C. sativa) were screened for resistance to chestnut blight. One hybrid and a C. crenata were partially susceptible, and two hybrids were partially resistant to chestnut blight. A total of 179 seedlings were inoculated with two virulent and one hypovirulent strain of Cryphonectria parasitica at two dates (early June and early September). Stromata production was higher and canker size larger when seedlings were inoculated in early June. Differences in canker size among seedlings derived from different parental trees were observed only after September inoculation. However, differences in canker size among seedlings inoculated with the virulent strains were observed only after June inoculation. The only significant effect on seedling survival was based on fungal strains used for inoculation.

Two-year-old chestnut seedlings of eight progenies, derived from open and controlled pollination of three hybrids (Castanea sativa × C. crenata and a C. crenata tree by paternal tree of C. sativa) were screened for resistance to chestnut blight. One hybrid and a C. crenata were partially susceptible, and two hybrids were partially resistant to chestnut blight. A total of 179 seedlings were inoculated with two virulent and one hypovirulent strain of Cryphonectria parasitica at two dates (early June and early September). Stromata production was higher and canker size larger when seedlings were inoculated in early June. Differences in canker size among seedlings derived from different parental trees were observed only after September inoculation. However, differences in canker size among seedlings inoculated with the virulent strains were observed only after June inoculation. The only significant effect on seedling survival was based on fungal strains used for inoculation. Ratio of seedlings, which died after inoculation with the hypovirulent strain, was significantly lower (36.8%) than those that died after inoculation with virulent strains (88.4 and 95.1%). Survival of seedlings was affected only by fungal strains used in inoculation, and not influenced by parental trees.

Disease symptoms, some important characteristics in pure culture, and distinctive morphological features of C. pini associated to the health state degradation in Austrian and Ponderosa pine are described and compared. Cumulative effects of these stressful biotic and various abiotic factors may explain the current situation concerning the decline in the P. nigra and P. ponderosa var. jeffreyi in Slovakia. |
