Opis:
The quantitative and qualitative analysis of mycorrhizae was done for Scots pine in plantation established on post−agricultural land. The state of mycorrhizae depended on the applied method of soil preparation (full deep ploughing, full ploughing with subsoiling, full shallow ploughing and ridge formation) as well as the presence and density of introduced land improving species (5, 3, 1.5 thousand/ha).

Opis:
The effect of two fungicides Falcon 460 EC and Gwarant 500 SC on the state of mycorrhizae and growth of 2−year−old pine seedlings in natural regenerations was investigated. Any of the tested fungicides did not cause changes in the level of mycorrhizal colonisation and seedling growth. Both fungicides had a limiting effect on the formation of one of mycorrhizal morphotypes and development of complex forms produced by this morphotype.

Opis:
Nanoparticles are gaining ever−wider application in plant production (for both agriculture and forestry), in the role of pesticides, as well as stimulators of plant growth and resistance. We sought to determine the efficacy of silver and copper nanoparticles (AgNPs and CuNPs respectively), used as seed dressings or subjected to foliar application, in affording protection from parasitic damping−off disease among soil−grown seedlings of Scots pine in a forest nursery. Experiments also assessed the influence of the nanoparticles on the growth of the plants potentially safeguarded in this way. Nanoparticles were used in seed soaking and foliar spraying at 50 ppm concentration. Pines treated with fungicides (Zaprawa Nasienna T 75 DS, Acrobat MZ 69 WG, Topsin M 500 SC, Gwarant 500 SC, Thiram Granuflo 80 WG and Signum 33 WG) or unprotected at all were used for comparison. In each treatment (AgNPs, CuNPs, fungicides or unprotected), seedlings were inventoried 6 weeks after the sowing and at the end of the growing season, while all individuals on 80 1−m−long segments of seed row were counted. At the end of the growing season, shoot length, root−collar diameter, root length and dry mass of shoots and roots were determined. The seedlings treated with nanoparticles had longer root systems of greater dry mass, but also only more weakly−developed above−ground parts (both height and dry mass being limited) in comparison with young Scots pines that had been fungicide−treated or were unprotected. It resulted in a significantly more favourable ratio between shoot and root masses, where nanoparticle treatment had been applied. The effectiveness of the protection extended to the germination and first−growth stages up to 6 weeks from the time of sowing was furthermore shown to be greatest where AgNPs had been applied, while at the season end there were comparable results among pines treated with either nanoparticles or fungicides. Our results thus indicate that nanoparticles limit damping−off disease in pine seedlings (AgNPs more effectively than CuNPs), with that effectiveness also proving comparable with that noted for the fungicides applied traditionally.

The aim of the study was to assess the effect of the application of Sincocin AL and inoculation with the fungi Hebeloma crustuliniforme or Laccaria bicolor on the growth and level of mycorrhizal colonization of Scots pine seedlings. Sincocin had no effect on the development of biometric parameters of pine seedlings inoculated with L. bicolor, it limited the growth of non−inoculated seedlings and stimulated the growth of the seedlings from the variant with H. crustuliniforme. Sincocin did not cause changes in the proportion of the mycorrhizae formed by H. crustuliniforme or L. bicolor, and affected in different ways (stimulation, inhibition, no effect) the spontaneous formation of mycorrhizae.

Both treatments stimulated the growth of seedlings. The effect of Biochikol was found only in the nursery irrespective of the used doses of the preparation. The effect of mycorrhization on pine growth was stronger compared to the application of Biochikol both in the nursery and plantation.

Three methods were used to assess silvicultural quality of two−year−old Scots pine (Pinus sylvestris L.). The assessment was based on measurements of biometric parameters, colonisation level of micorrhizas and electrical impedance of cambial tissues of shoots. The applicability of these methods with special reference to micorrhizal colonisation and impedance methods, which so far were not used in the assessment of the planting material, was analysed.

Opis:
Mechanical site preparation is recommended to create optimum conditions for seed germination and seedling growth in a clear−cut area. Lack of soil scarification or less−intense methods may be more suitable from an environmental point of view, but can result in a failure to obtain natural regeneration. This study compared the effects of three mechanical site preparation methods (SPM) characterized by different levels of soil scarification (i.e. double mould−board forest plough (LPz), active plough (PA) or forest mill (FL)), as well as a control variant without mechanical site preparation, on height, density, spatial distribution and survival among naturally regenerating Scots pines (Pinus sylvestris L.) in the first 2 years of growth in a clear−cut area of NE Poland. The experiment was based around a four−block randomized block design involving the four variants. Seedling height was measured at the end of the first and second growing seasons, with measurements performed on 8 meter−wide transects extending across the entire width of the cleat−cut. We found no effect of SPM on seedling height, though the density of seedlings regenerating naturally was found to be dependent. After two years, the highest density was achieved in the PA variant (8.1 seedlings/m2) and the FL variant (7.0 seedlings/m2). A significantly lower density characterized the LPz variant (5.1 seedlings/m2) and the lowest of all the variant without soil scarification (3.2 seedlings/m2). The most homogeneous natural regeneration was achieved following the use of PA (2.6% of 1 m2 plots without seedlings after two growing seasons), while the least homogeneous was the variant without soil scarification (22.4% of 1 m2 plots). Survival of pines after the second growing seasons was quite high (over 80%), and did not differ significantly depending on the SPM. Our research therefore confirmed that, in the absence of mechanical site preparation, natural regeneration of sufficient density and homogeneity cannot be obtained. The best natural regeneration was obtained on sites prepared with PA, and FL scarification being only slightly less favorable. The low density and uneven distribution of seedlings on the soil prepared with LPz was a surprising result. The probable reason for this lay in the high precipitation in the first growing season. On one hand, this provided very good moisture conditions for seed germination and seedling growth on a substrate with high porosity in the PA and FL variants, but on the other the high bulk density of mineral soil in the LPz variant led to oxygen deficit.

Opis:
Since its initial discovery in 1945, pitch canker caused by Gibberella circinata (anamorph Fusarium circinatum) has become one of the most important pine diseases in the world. It infests 57 pine species (including Pinus sylvestris) and Douglas−fir. F. circinatum has been reported in both nurseries and forests on all continents except Australia and Oceania. Both vegetative and reproductive parts of the host plant (i.e. stem, branches, roots, flowers, cones and seeds) can be infected by F. circinatum. For mature trees, the main symptoms include bleeding resinous cankers on the stem and branches as well as tree death. In nurseries, F. circinatum causes pre− and post−emergence damping off as well as mortality of older seedlings. Dispersal of fungal spores occurs through air, water splash, soil, insect vectors and translocation of the infected plant material. Currently there are no effective means of controlling pitch canker, although there is ongoing research into using chemical, physical and biological methods, quarantine and breeding for resistance to control this disease. The occurrence of the disease depends mainly on the presence and density of the host species, favorable climatic conditions (especially high humidity), presence of suitable vectoring and wounding agents and various stress factors. Taking into account the above−mentioned factors, threat to Scots pine in Poland should be considered marginal, but it cannot be ruled out completely. KEY WORDS

Opis:
Different methods of logging slash management (LSM) and methods of soil preparation (MSP) can create different conditions for the growth of forest trees. This occurs through variation in soil aeration, tree nutrition or microbial conditions. These factors are modified by climate, soil fertility, treats from insects or fungal pathogens and renewed species. The aim of this study was to compare effects of three LSM methods: 1) crushing and mixing with the soil by Mery Crusher, 2) chopping and leaving on the soil surface, and 3) removal from the clear−cut, and three MSP: 1) double−mouldboard forest plough LPz−75, 2) active plough U−162, and 3) forest mill FAO−FAR FV 4088 on biometric parameters, density and survival of six−years old Scots pine seedlings. Field research was conducted in Narol Forest District (south−eastern Poland). The soil in the study area was classified as brown podzolic, formed on loose sands with typical mor humus.The experiment was established by planting 10 000 one−year−old pine seedlings per hectare, after clear cut and followed by a two−factor block design consisting of nine variants distinguished on the basis of LSM and MSP randomly assigned to each of the three blocks. Tree height and root collar diameter were measured three times, at the end of 1st, 3rd and 6th growing season. The results showed no statistically significant differences in the size of the analyzed parameters of planted seedlings. Seedlings in the variant with site preparation by crusher and forest mill were slightly higher and thicker. This indicates the better trophic conditions in that variant. LSM did not affect either seedlings density or their survival. A slightly higher survival rate and tree density occurred in variants with crusher regardless of soil preparation method. It follows that, all presented experimental variants give similar results. Therefore, selection of the most appropriate methods of site and soil preparation should primarily respect ecological and economic indicators, and such local factors as microclimate, mainly precipitation, site fertility and threats from pests and fungal diseases.

The effect of two fungicides Falcon 460 EC and Gwarant 500 SC used at recommended rates and concentrations to protect seedlings in the natural regeneration of Scots pine against Lophodermium needle cast was investigated. Also, the effect of the fungicides on the status of mycorrhizae and growth of seedlings was assessed. Single or twofold application of Falcon or Gwarant to pine seedlings during the growing season may appear insufficient to provide complete protection against Lophodermium needle cast, especially when the threat of infection is higher. Falcon was found to be more effective in protecting pine seedlings against Lophodermium needle cast in comparison with Gwarant. None of the tested fungicides had a limiting effect on the formation of mycorrhizae and growth of seedlings. Both fungicides had a slight limiting effect on the formation of complex dichotomous and coralloid structures only in one−year−old pines.
