Lyon Arboretum Facility – FY 2010 Report

Between the period of July 1, 2009 and June 30, 2010, the Lyon Arboretum Micropropagation Laboratory received 390 submissions representing 75 native Hawaiian species; 41 (55%) of these species are listed as Endangered and 9 (12%) are Species of Concern. Currently, the Micropropagation Laboratory has a total inventory of 11,246 plants consisting of 218 native plant taxa at various stages of propagation in the lab. Of these plants, 7574 are Plant Extinction Prevention species. The current inventoried taxa consist of 132 endangered (61%), 26 (12%) Species of Concern, 8 (3.5%) Candidate, and 52 (23.5%) common taxa. Submissions of eight new native species have been made into the lab of which 2 are endangered. A total of 1,028 plants have been sent out of the micropropagation and greenhouse facility for restoration purposes, of which 750 were individuals of Plant Extinction Prevention species.

Lyon Arboretum’s Hawaiian Rare Plant Program submitted a manuscript, under the authorship of Nellie Sugii, to InVitro Cellular and Developmental Biology-Plant (ISSN 1054-5476). This manuscript entitled “The Establishment of Axenic seed and Embryo Cultures of Endangered Hawaiian Plant Species: Special Review of Disinfestation Protocols” is at the final stages of a refereed review process. Three posters featuring the research conducted at the Hawaiian Rare Plant Program-Lyon Arboretum were presented at national meetings:

  • American Society of Horticultural Science Annual Conference, Palm Desert, California, August 2-5, 2010, “In Vitro Germination of Four Rare Endemic Hawaiian Cyanea ssp. for Restoration of Plants Extinct in the Wild”
  • 2010 In Vitro Biology Meeting with the International Association for Plant Biotechnology (IAPB) and the Society for In Vitro Biology (SIVB), St. Louis, Missouri, June 6-11, 2010, “Use of In Vitro Propagation in Maximizing Germination of Lobelia monostachya (Rock) Lammers”
