Several storage treatments at 20 °C and −5 °C were evaluated by late spring transplantings for fall and spring lifted 2-0 seedlings of Pinus sylvestris L. and Picea pungens Engelm. Survival and growth of the 2-2 transplants for both species, after overwinter or early spring storage at 2 °C as bare-root plants in sealed 4-ml poly bags, equalled the performances of freshly-lifted seedlings. Both of these treatments proved practical and efficient alternatives for delayed spring transplantings. Overwinter storage at −5 °C apparently reduced transplant survivals of immature Colorado spruce seedlings and proved lethal for Scots pine seedlings lifted on October 16.

Phytotoxic Effect

In temperate European forests invaded by Prunus serotina Ehrh. (black cherry), a reduction in the spontaneous regeneration capacity of Pinus sylvestris L. (Scots pine) is observed. It could be caused by various factors, including allelopathic properties of this invasive plant. In this study the phytotoxic effect of P. serotina volatile compounds on P. sylvestris and the seasonal variation in this effect were assessed. Simple assays showed that volatiles emitted from P. serotina leaves significantly inhibited root growth of P. sylvestris seedlings. Their negative effect on stem growth was much weaker. The strongest phytotoxic effect on Scots pine seedlings was caused by the volatiles emitted from the youngest black cherry leaves. In fresh foliage of P. serotina, nineteen volatile organic compounds were identified by gas chromatography–mass spectrometry (GC–MS). The dominant compound was benzaldehyde. On the basis of tests of linalool alone, it was found that this monoterpene present in the volatile fraction has a strong allelopathic potential and inhibits germination, root elongation and shoot elongation of pine seedlings. The results of our research suggest that volatile compounds from P. serotina leaves could limited survival of P. sylvestris individuals in the seedling phase.

Scots pine provenances from Russia were grown in Ontario at Longlac, Dorset and Chalk River, and in Saskatchewan at Prince Albert and Indian Head. After eight growing seasons in the field all provenances survived well. The three tallest, Orel, Woronesh and Kiev provenances, grew considerably taller than the others, and at Prince Albert, where native jack pine was also grown, the growth and survival of these provenances was also better than that of jack pine. If further studies show that this high performance persists and that stem form is commercially acceptable, seedlings from these three provenances may be useful for reforestation in those parts of Canada with a continental climate.

Scots pine (Pinus sylvestris) is an economically important source of timber in Mongolia and has been widely used in reforestation programs. In this study, we investigated the effects of mycorrhizas on the growth of pine (Pinus sylvestris) seedlings. Inoculation with ectomycorrhizas and endomycorrhizas increased the height, root length, and root collar diameter of the pine seedlings compared to the non-inoculated seedlings. Furthermore, the results of the study showed that the percentage survival rate is higher in mycorrhizal inoculated pine seedlings than control seedlings. These results demonstrated that inoculation could effectively form ectomycorrhizas with pine seedlings and promote its growth, which can be used to restore Mongolian forest.

Abstract Five-year-old Norway spruce and four-year-old Scots pine seedlings of various origin were inoculated with Heterobasidion annosum s.s. and H. parviporum to estimate whether the susceptibility of seedlings to Heterobasidion was affected by origin of seeds. In total, 520 spruce and 538 pine seedlings from different seed sources and provenance regions of Latvia were tested. Four months after inoculation the fungal growth was measured. The results highlight differences between development of H. annosum and H. parviporum in spruce and pine seedlings. We did not find any seed source that was more resistant than others.

Nitrates of aluminum, cadmium, manganese and lead cause changes in the content of phenolic compounds (o-dPh and TPh) in needles and roots, and in the rate of dark respiration (DR) of roots of one-year-old seedlings of Scots pine (<i>Pinus sylvestris</i> L.). The changes depend on the cation, the salt concentration used, and the analyzed plant part. The observed changes in the levels of phenolic compounds in needles and roots, and the rate of respiration in roots, indicate the following rank in toxicity of the studied metal cations: Mn < Al < Pb < Cd.

AbstractWe studied the effect of regeneration (planting/seeding) and soil preparation methods (no soil preparation/scalping/mounding) on the regeneration success of Scots pine (Pinus sylvestris L.) on three drained peatland Scots pine stands in northern Finland. After ten years, planting and sowing showed no differences in the total number of Scots pine seedlings (one seedling per sowing spot accepted) with the exception of the Sievi experiment. Without soil preparation the total number of Scots pine seedlings was 350–600 per ha. Scalping increased the number of Scots pine seedlings to 550–900 per ha, with the exception of seeding at Sievi. In mounded plots, with the exception of seeded plots at the Sievi site, the number of planted or seeded seedlings was 1,325–2,350 per ha. The number of crop seedlings in all the experiments and for all the soil preparation treatments reached the target of 2,000 seedlings per ha if naturally regenerated Scots pine, Norway spruce (Picea abies (L.) H. Karst.) or birch (Betula spp.) seedlings were accepted as such. Moose (Alces alces L.) damage in Scots pine crop seedlings ranged from 4% in Sievi to 65% in Simo. The proportion of planted or seeded Scots pines of the crop seedlings was 23% in unprepared plots, 30% in scalped plots and 75% in mounded plots. Mounding increased the share of Scots pine seedlings in the overall crop seedlings. Planted seedlings were taller than seeded seedlings. Planting in mounds gave the best overall results in terms of the number of crop seedlings and their height ten years after the treatment.

Although several organic and inorganic substrates are added to growing media for improving its physical and chemical characteristics, the need for search of new materials and/or mixtures that reduces the high-priced peat content in substrates is still interesting. This study evaluated the feasibility of reducing the peat content in substrates by replacing it with different amounts of diatomite and sewage sludge for Scots pine seedling (Pinus sylvestris L.) growth and their land performance. In order to evaluate the feasibility of reducing the peat content in substrates by replacing it with different amounts of diatomite and sewage sludge, an experiment was carried out in a temperature-controlled greenhouse under natural light. To evaluate the land performance of Scots pine seedlings grown in different substrates, a trial was established between the years 2013-2017 in Sar&#305;kam&#305;ş, Kars (NE Anatolia). Sewage sludge application, due to its high organic matter and macro and micronutrient content, has improved the composition of the rhizosphere, thereby resulting in growth acceleration. As a result of the evaluations made in terms of both seedling morphological characteristics and land performance; the best performance was determined in the 9<sup>th</sup> (50%P+50%SS) and 3<sup>rd</sup> (75%SS+25%DE) mixtures.
