RESEARCH: SUPER DWARF
CULTIVAR STUDIES: 'APOGEE' WHEAT |
|
|
"Apogee": The point in an orbit farthest from the
earth.
'USU-Apogee' was developed for high yields in space. Crops
for the space station need to be short so they can be grown on
shelves. 'USU-Apogee is half the height of normal wheat.
It has few tillers (branches) and smaller leaves than wheat on
Earth. Tillers and large leaves compete with other plants
and reduce the yield of plant communities. Two small
leaves are better than one large leaf.
"Perigee": The point in an orbit closest to the earth.
'USU-Perigee' and 'USU-Apogee' both came from a hybrid cross between
'Super Dwarf' Wheat and 'Parula'. 'Perigee' is shorter than
'Apogee' but has a slightly longer life cycle.
