Different Types

The paper reviews the present knowledge of Scots pine (Pinus sylvestris L.) diversity, historical and geographical distribution, based on mitochondrial and chloroplast DNA data. The observed differences in the estimates of genetic differentiation between different types of genomes suggest that both pollen and seed contribute significantly to gene flow within species. Organelles' diversity represents an important criterion which could be later applied in planning for future forest management and breeding through a better understanding of adaptation strategies of different Scots pine haplotypes. This analysis would provide valuable references when facing current day problems with climate change, species adaptation, and loss of forest with negative effects on biodiversity. Research on organelles' diversity could lead to important practical applications in areas such as traceability and eco-certification of forest products, and the identification of plant populations for conservation. Based on the results from earlier investigations, Scots pine in Europe can be divided into at least three evolutionary units (Spain, northern/central Europe and northern Fennoscandia), each with a different origin after glaciations. However, it must be emphasized that these interpretations are preliminary and further mitochondrial and chloroplast DNA data need to be analyzed in conjunction with evidence from pollen and fossil analysis.

Climate Proxies

Six chronologies based on the growth of Scots pine from the inland of northern Fennoscandia were built to separately enhance low, medium, and higher frequencies in growth variability in 1000–2002. Several periodicities of growth were found in common in these data. Five of the low-frequency series have a significant oscillatory mode at 200–250 years of cycle length. Most series also have strong multidecadal scale variability and significant peaks at 33, 67, or 83–125 years. Reconstruction models for mean July and June–August as well as three longer period temperatures were built and compared using stringent verification statistics. We describe main differences in model performance (R2 = 0.53–0.62) between individual proxies as well as their various averages depending on provenance and proxy type, length of target period, and frequency range. A separate medium-frequency chronology (a proxy for June–August temperatures) is presented, which is closely similar in amplitude and duration to the last two cycles of the Atlantic multidecadal oscillation (AMO). The good synchrony between these two series is only hampered by a 10-year difference in timing. Recognizing a strong medium-frequency component in Fennoscandian climate proxies helps to explain part of the uncertainties in their 20th century trends.

Seed Maturity

To determine whether leakage from seeds during imbibition could be used to determine maturity of Pinussylvestris L. seeds, leachate conductivity and amounts of carbohydrates and inorganic phosphorus were measured for seeds repeatedly collected from three localities in northern Fennoscandia during the ripening season. The seeds were also radiographed and tested for germination. Leachate conductivity as well as the leakage of inorganic phosphorus and carbohydrates decreased during ripening with increasing anatomical and physiological maturity until the approximate time for cessation of anatomical development. No further anatomical development occurred when leachate conductivity was lower than 6 μS•cm−1•seed−1 and the seeds were not physiologically mature as long as leachate conductivity exceeded 3–5 μS. Leachate conductivity and the amount of leached carbohydrates were 4–8 and 10–15 times higher, respectively, in nongerminable than in germinable seeds. Using regression analysis the germination percentage during ripening could be estimated with r2 between 0.96 and 0.99 with anatomical potential and leachate conductivity as explanatory variables. It is concluded that leachate conductivity measurements can be very useful for determination of Scots pine seed maturity.
