EXPERIMENT INFORMATION

Karyological Observations in Developing Root Seedlings (OSS-1.2)
Principal Investigator
Research Area:
Plant biology
Species Studied
Scientific Name: Avena sativa Species: Oat
Scientific Name: Vigna radiata Species: Mung Bean

Description
Objectives:

Examination of plants grown under microgravity is still in its infancy. As more opportunities arise for making observations on space-grown material, it benefits investigators greatly to learn as much as possible, however fragmentary, from flight samples. As part of a larger investigation conducted in cooporation with the HEFLEX experiment flown on both STS-2 and STS-3, this study sought to utilize oat and mung bean root seedlings germinated in space for karyological examinations.
