Nothofagus Alpina - Frost Hardiness Study in Britain

Frost Hardiness Study in Britain

Provenance sources from different places from its natural environment were tested in cultivation at the Bush estate in Scotland. Seedlots of Nothofagus alpina and Nothofagus obliqua were tested. The results of the testing in relation to the sources were reported as:

  • Nuble in Chile. This was the most equatorial source and these seedlots proved to be the most susceptible to frost.
  • Neuquen in Argentina. These seedlots, as well as those gathered from mature trees growing in Britain with origins from Malleco in Chile were the most hardy. Overall, Nothofagus procera performed better than Nothofagus obliqua.

Past temperature records for Britain suggest that seedlots run a high risk of suffering severe frost damage in all but mild coastal regions, and that spring and autumn frosts may be more damaging than winter frosts. The Nothofagus alpine's leaves grow down towards the ground.

Famous quotes containing the words frost, study and/or britain:

    What an exciting age it is we live in
    With all this talk about the hope of youth
    And nothing made of youth.
    —Robert Frost (1874–1963)

    It’s worth living abroad to study up on genteel and delicate manners. The maid smiles continuously; she smiles like a duchess on a stage, while at the same time it is clear from her face that she is exhausted from overwork.
    Anton Pavlovich Chekhov (1860–1904)

    Hath Britain all the sun that shines? day? night?
    Are they not but in Britain?
    William Shakespeare (1564–1616)
