High impact information on Tsuga

  • Sap flux density was 1.41 times higher in young red alder (Alnus rubra Bong.) compared with young P. menziesii trees, and was 1.45 times higher in old P. menziesii compared with old western hemlock (Tsuga heterophylla (Raf.) Sarg.) trees [1].
  • Alpha-linolenic acid and its delta5-desaturation product, coniferonic acid, in the seed lipids of Tsuga and Hesperopeuce as a taxonomic means to differentiate the two genera [2].
  • This suggests that C4 plants (transmorrisonensis) have replaced C3 plants of Tsuga and nittakeyamensis [3].
  • The nuclei themselves, as studied in Tsuga seed wings, were found to contain mainly catechin, much lower amounts of epicatechin and traces of proanthocyanidins [4].
  • Wood specific gravity was determined for three species of forest trees (Acer rubrum, Fagus grandifolia and Tsuga canadensis) growing in central Massachusetts, USA [5].
 

Associations of Tsuga with chemical compounds

  • The delta13C values of the Tsuga forest area (pedon 4) range from -27.0 per thousand to -23.5 per thousand and showed only slight change with soil depth, implying that C3 plants have remained the major species in the forest [3].
  • Tsuga canadensis has significant amounts of vacuolar flavanol deposits in all parts of the tree as indicated by the DMACA reagent [6].
  • Damage to trees increased in the order: Tsuga canadensis, Betula alleghaniensis, Ostrya virginiana, Acer saccharum, Fagus grandifolia, Quercus rubra, Betula papyrifera, Acer rubrum, Tilia americana, and Fraxinus americana [7].
 

Gene context of Tsuga

  • Onion cepa (L.) and Tsuga canadensis (L.) Carr. were investigated histochemically on the association of flavanols to nuclei [6].
