Growth and water relations of three geographically separate origins of maritime pine (Pinus pinaster) under saline conditions

Abstract: Water relations and growth of maritime pine (Pinus pinaster Ait.) were investigated in 2-year-old seedlings of French ('Landes'), Iberian ('Iberian') and Moroccan ('Tamjoute') origin raised for 67 days in a flowing solution culture system containing 0, 50, 150 or 250 mM NaCl. Height growth, and stem, needle and root dry matter were reduced by salinity with minor differences among geographic origins. Predawn needle water potential was decreased by salinity and corresponded approximately to the osmotic potential… Show more

“…The results should be interpreted with some caution, since the response of the parameters under study depends on the season, cultural conditions, seed origin and species [4,27,31,41,42] and even on the nature of the tissue sampled from the plant [38]. Colombo [6], in his work with Picea mariana, obtained similar or opposite results to those of other authors, and he suggested some reasons to justify the lack of a uniform pattern for ϵ.…”

“…The restriction of growth due to lack of available water is a well-known general response of plants [5]; such observations have been made in 1-year-old P. pinaster [16]. For 27 July for the R2, suggested that many plants had exceeded the turgor loss point. As a consequence, an increase in mortality was observed.…”

“…The study by Harfouche et al [27,28], relevant to intraspecific hybrids of this species, revealed that the Moroccan population in the region of Tamjout was resistant to Matsucoccus feytaudi and that the hybrids of this provenance with other origins (e.g., Leiria in Portugal or Cazorla and Vivario in Spain) were also resistant to the pest. Tamjout is also considered as the most tolerant provenance to water and saline stresses in the maritime pine native range [25,31,37]. A recent study using allozyme markers showed that genetic variation of maritime pine in Morocco was highly structured (θ = 10.44%).…”

“…Previous studies highlighted that increasing salinity levels significantly decrease stomatal conductance, produce more negative water potentials, and decrease root hydraulic conductance, resulting in decreased water content in the plant [4,5,18,54]. Begley et al [20] detected differences in the absorption bands of water at 1806 nm that were well correlated with different concentrations of NaCl in meat.…”
