The snow gum is one of the most frost hardy of eucalypts (Sakai et al.
Thus, while recognizing that many parameters covary with irradiance, the study used a simplified system to test for effects of excess irradiance on growth of over-wintering snow gum seedlings under field conditions.
Our results show that reduction in excess irradiance increases growth of snow gum seedlings over winter.
1997) imposed treatments that varied minimum air temperature by as much as 2[degrees]C with no effect on maximum air temperature around snow gum seedlings grown in full sunlight under field conditions.
Thus, the vertically inclined leaves of snow gum seedlings experienced more prolonged exposure to higher irradiance in winter than autumn.
1998) found growth of the most photoinhibited snow gum seedlings planted in the open to be greater over winter than growth of the least photoinhibited seedlings planted under the dense canopy shade of forest fragments.
Microclimate above grass adversely affects spring growth of seedling snow gum (Eucalyptus pauciflora).
Cold-induced photoinhibition limits regeneration of snow gum at tree line.
Cold-induced photoinhibition and growth of seedling snow gum (Eucalyptus pauciflora) under differing temperature and radiation regimes in fragmented forests.
Ideal for small gardens because it rarely exceeds 30ft, the Snow Gum is an outstanding ornamental, of year-round interest and beauty as the bark peels away to reveal a mixture of silver, grey-green, cream, and pale green, sometimes tinted red.
For a species associated with the sun burnt expanses of Australia, the Snow Gum is not happy in dry, chalky conditions, preferring most well-drained soils.
