Summary:
The Agryroxiphium sandwicense, (silversword), is a giant rosette plant that grows at the high elevation levels of two Hawaiian volcanoes where nighttime subzero temperatures frequently occur. This study investigates the ability of the seedlings of the A. sandwicense to adjust photosynthetic processes to different growing temperatures. This seedling's ability to tolerate temperatures that range from 15 - 60 degrees Celcius through a combination of field and laboratory studies was also investigated. Altitudinal changes in temperature were also analyzed in an effort to explain the observed spatial distribution of A. sandwicense. Plant material and field measurements were done on the Argyroxiphium sandwicense sp. macrocephalum seeds that were taken from 15 plants from 10 different populations that occur in the Haleakala National Park on the island of Maui.
