Facilitation of Seedling Establishment: Reduction in Irradiance Enhances Winter Growth of Eucalyptus pauciflora
We determined whether plants benefit from a reduction in irradiance when growth is limited by low temperatures. Growth of snow gum (Eucalyptus pauciflora Sieb. ex Spreng.) seedlings was studied in response to two irradiance regimes (100% and 50% sunlight) under field conditions during autumn and winter. Seedlings were planted on north (exposed) and south (sheltered) sides of vertical screens transmitting 50% incident sunlight. This planting arrangement allowed assessment of affects of excess...[Show more]
