Estimates of heritability and associations of tiller number,
seed number, seed weight, and seed yield were determined in two
groups of tall fescue. Group E was early maturing and had eight
parental clones, while group I was intermediate in maturity and had
nine parental clones. The parents and five progeny...
The winter and summer growth of varieties of tall fescue
(Festuca arundinacea Schreb.) that had originated from the Mediterranean region (Oregon 1000 and Tunisia) and northern Europe (Alta)
were studied outdoors in the Mediterranean climate of western Oregon,
and in greenhouses and controlled environment chambers. Treatments
of temperature, photoperiod and...
Dormancy in seed of Festuca arundinacea Shreb. was
studied.
The
acquisition of dormancy during seed maturation was
examined and the
effect on dormancy relief by chemical and
physical treatments was
determined.
The implication of endogenous growth inhibitors
in
dormancy imposition and maintenance was assessed.
Germination responses
to temperature and growth...
The response of maturity, vigor, plant spread, plant height,
three forage harvest yields, and total forage yield to heterosis and
inbreeding was studied in tall fescue. Parent clones selected for
diverse anthesis date, origin, and morphology were separated into two
groups based on anthesis date, those having early maturity and...
Tall fescue often results in poor liveweight gains. This may be accounted for by variations in perloline content, nitrogen content, or digestibility of the plant. Two groups of tall fescue plants were examined for each of these traits. These groups consisted of (a) fifteen single-crosses of a six parent diallel...
Two cultivars of tall fescue (Festuca arundinacea
Schreb.) with contrasting growth habits were studied under
field and growth chamber conditions. Fawn, an established
cultivar since 1964, and TFM, an experimental line, were
observed to grow better during spring and fall months
respectively, in the field. Different temperature regimes
of 10/4,...
