PATTERNS OF CARBON ALLOCATION IN AN ARCTIC TUNDRA GRASS, DUPONTIA FISCHERI (GRAMINEAE), AT BARROW, ALASKA
In Dupontia fischeri R. Br. the pattern of translocation of photosynthetically incorporated 14 C was established within six hr after treatment in situ at Barrow, Alaska. More radiocarbon went to younger rather than older tillers. The most effective sinks were root, lateral root, and rhizome primordi...
