grew less dense at Prudhoe. This was consistent 
with results obtained in 1973. Two plants of the 
Kenai Peninsula entry recovered sufficiently 
from winter injury to produce seed heads in 
1974, which grew the tallest at the Prudhoe site 
followed by an entry from a northern boreal 
station (Fort Yukon). The plants in the Prudhoe 
garden bore wider leaves than those in the 
Palmer garden, as they did in 1973. 
Three of the arctic entries produced from 
about two to almost five times as many flower- 
ing culms as the other entries in both the Palmer 
and Prudhoe gardens (Fig. 5). This represented a 
tremendous increase in flowering culm produc- 
tion from the previous year. One arctic biotype 
from the Brooks Range (Atigun Canyon) 
resembled the Fort Yukon entry more than the 
coastal arctic forms in flowering culm produc- 
tion. 
The arctic and boreal entries generally differ- 
ed little in shoot weights (Fig. 6). All of the 
entries except the Barrow entry produced more 
top growth at the boreal site than at the arctic 
site. A Prudhoe Bay biotype and Fort Yukon 
biotype were the highest producers at both sites. 
The arctic biotypes compensated for their short- 
er growth with the production of more flower- 
ing culms and generally a more dense growth to 
yield as much as the boreal types. 
Deschampsia caespitosa 
The three Colorado entries and one from the 
Kenai Peninsula (Turnagain Pass) in southcentral 
Alaska, all tetraploids, winter-killed at both sta- 
tions in 1973. An octoploid boreal entry from 
the southern interior region of Alaska (Copper 
Center) was severely winter injured in the 
Palmer garden in 1974. 
The arctic and alpine entries grew shorter at 
Palmer than they did at Prudhoe, which general- 
ly was consistent with results obtained in 1973 
(Fig. 7). The single boreal entry (IAS 145, Cop- 
per Center) that survived in both gardens grew 
considerably taller than the other entries at 
Palmer. The boreal entry grew longer leaves but 
shorter and much fewer flowering culms at 
Prudhoe than it did at Palmer. 
The arctic and alpine entries increased appre- 
ciably in flowering culm production over the 
previous year at Prudhoe (Fig. 8). The tetraploid 
boreal entry (Copper Center, 145) declined in
