Reconnaissance chimiosystématique et biométrique du pin de tourbière Pinus x uliginosa (Neumann)

Taxonomic differences among closely related pines Pinus sylvestris, P. mugo, P. uncinata, P. rotundata and P. uliginosa as revealed in needle sclerenchyma cells

“…A close relationship of P. uncinata to P. mugo has been inferred based on flavonoid contents and needle morphology (Lauranson-Broyer et al, 1997). In all the above-mentioned studies, P. uncinata was always more closely related to P. mugo than to P. sylvestris.…”

Pinus mugo (Pinaceae) in the Abruzzi Mountains: high morphological variation in isolated populations

“…The suspected flow of genes from P. sylvestris L. into taxa of the P. mugo complex has also been verified in several studies. Gene flow was examined on the basis of morphological features (Christensen & Dar, 1997; Lauranson‐Broyer, Krzakowa & Lebreton, 1997; Boratyńska et al ., 2003), isozymes (Neet‐Sarqueda, Plumettaz Clor & Becholey, 1988; Neet‐Sarqueda, 1994; Siedlewska & Prus‐Głowacki, 1995; Prus‐Głowacki, Bujas & Ratyńska, 1998; Lewandowski et al. , 2002) and DNA (Filppula, Szmidt & Savolainen, 1992; Odrzykoski, 2002; Wachowiak, 2003).…”

Evidence of natural reciprocal hybridisation between Pinus uliginosa and P. sylvestris in the sympatric population of the species

“…Considering the taxonomic revision of the P. mugo complex, P. uliginosa is classified as a synonym of P. rotundata and described as a hybrid between P. mugo and P. uncinata (Christensen, 1987). It is also considered to result from P. mugo, P. uncinata and P. sylvestris hybridisation (Lauranson-Broyer et al, 1997) or to form a stabilized hybrid taxon in the consequence of P. mugo and P. sylvestris ancient cross pollination (Mirek et al, 1995;Staszkiewicz, 1993).…”
