  • Planning, setting up, and analyzing experiments for improving micropropagation of woody plants. 
  • Investigating and optimizing mineral nutrition in tissue culture media by eliminating physiological disorders in vitro micropropagation systems.
  • Testing, developing and applying cryopreservation methods for diverse/endangered germplasm, and spores of hop powdery mildew, Podosphaera macularis, in liquid nitrogen for long-term back up.
  • Testing rooting potential and developing optimal protocols to shorten the production cycle for woody nursery crop rootstocks.
  • Examine basic seed biology and seed dormancy mechanisms by systematic and anatomical approaches using microtome, light and electron microscopy.
  • Investigating effective scarification methods to enhancing seed germination for an economically important crop (Raspberry & Blackberry).
  • Botanical drawings for scientific investigation.
  • Plant systematics, taxonomy and identification.
  • Manuscript reviews for scientific publications.
  • Reporting and transferring the scientific findings to the public such as growers, commercial labs, and researchers through publications and OSU, USDA-ARS online resources.

Personal Interests: 

How to tell “diamonds” from “pearls” Barbara M. Reed, who’s a plant physiologist with our ARS National Clonal Germplasm Repository in Corvallis, Ore., has teamed up with Oregon State University colleagues Sugae Wada  to produce a 22-page guide that will help fruit processors, bakers, jam producers and blackberry connoisseurs tell whether they’re savoring the blackberry cultivar “Black Diamond” or perhaps “Black Pearl,” “Obsidian,” or some other luscious beauty. http://www.ars.usda.gov/is/noi/101015.htm

Saved for future generations :Just east of Corvallis is a gene bank that holds nearly 500,000 plant samples; some of are on their way to Norway's 'doomsday' vault so they'll be preserved from disaster. The repository is one of 20 USDA gene banks, which hold nearly 500,000 plant samples, including seeds, pollen and cuttings.The Peoria Road repository is run by the U.S. Department of Agriculture in cooperation with Oregon State University, which also leases the property to the federal agency.Hundreds of berry and fruit seeds from a Corvallis area facility will be stored in a "doomsday" vault in Norway, which  is designed to protect the world's plant species from extinction. Norway's government owns the $9.1 million Scandinavian vault, a backup to the world's 1,400 other seed banks. The underground "doomsday" vault in Svalbard sits in a frigid area only 620 miles from the North Pole. The inside of the vault is kept just below zero, a temperature at which the seeds could survive for 1,000 years, according to scientists.  http://www.gazettetimes.com/

Saved for future generations   Doctoral candidate Ms Sugae Wada from Horticulture Department Oregon State University is working in the NCGR seed lab for preparing/ shifting the seed samples to the doomsday seed valt in Svalbard, Norway.
