Microbial Community Analysis of Native Pinus sylvestris L. and Alien Pinus mugo L. on Dune Sands as determined by Ecoplates

Spontaneous Hybridization between Pinus mugo and Pinus sylvestris at the Lithuanian Seaside: A Morphological Survey

We address the problem of spontaneous hybridization between an exotic species Pinus mugo and the native/local P. sylvestris at the seaside spit of Kursiu Nerija in Lithuania. The objective was to identify spontaneous hybrids between P. mugo and P. sylvestris based on morphology traits among the individuals naturally regenerating at the seaside spit. The field inventory was carried out over the ...

The effects of abiotic and biotic factors on somatic embryogenesis and seedlings of Pinus sylvestris (L.)

Introgression between Pinus taeda L. and Pinus echinata Mill

Loblolly pine (Pinus taeda L.) and shortleaf pine (Pinus echinata Mill.) have widely overlapping geographic ranges. Hybridization between the two species has interested tree breeders for a long time. Morphologically, the two pine species are different. The needles of loblolly pine are 6 to 9 inches long, usually with three yellow-green needles per fascicle; but shortleaf pine needles are 3 to 5...

Impact of Drought on the Intra-Annual Growth of Pinus sylvestris L

Climatic scenarios for the Mediterranean Region forecast increasing frequency and intensity of drought events. We analyzed how Pinus sylvestris modifies its cambial phenology and intra-annual growth under enhanced drought conditions. For this purpose, a rainfall exclusion experiment was applied in 2012 to trees located in the lower elevation limit of a mountain forest in Central Spain. Prelimin...

Identification and Quantification of Indole-3-methanol in Etiolated Seedlings of Scots Pine (Pinus sylvestris L.).

Combined gas chromatography-mass spectrometry has been used to identify indole-3-methanol in a purified buffer extract from etiolated seedlings of Pinus sylvestris L. Quantitative estimates obtained by high performance liquid chromatography with fluorescence detection, corrected for losses occurring during purification, indicated that etiolated seedlings of P. sylvestris contained 19.7 +/- 1.4 ...
