Cheatgrass (Bromus tectorum L.) and yellow starthistle (Centaurea
soistitialis L.) have invaded over 3 million ha of grasslands in the western U.S.
Future management will require an understanding of the conditions,
mechanisms, and processes which control species dominance, community
dynamics, and desirable plant establishment in these alien dominated annual
rangelands....

Hydrogen cyanamide (CY) has been used to break rest
in temperate crops, but levels used to overcome rest are
sometimes toxic to plants. The rest breaking effect of CY
is thought to involve peroxide metabolism. Inhibition of
catalase by CY has been proposed as a mechanism for
overcoming dormancy in...
This research was conducted to determine the effects of
temperature and competition on seedling root and shoot growth of
cheatgrass (Bromus tectorum L.) and 5 collections of Idaho fescue
(Festuca idahoensis. Elmer). For the temperature study, seedlings
were grown in environmental chambers with 16 hours day/8 hours night, at
temperatures...
