Agronomics of reseeding winterkilled winter wheat: Author: Allen, Thomas Lee; Date: 2009-05-15; Program: Plant Science; Abstract: Winterkill has long been a problem for winter wheat growers in Montana. In any given year up to 50% of the seeded acres of winter wheat may have to be reseeded to spring wheat. Research has addressed injury thresholds on when to reseed winter wheat. But little information is available regarding reseeding to spring wheat. The objectives of this study were to determine the level of injury whereby it is more profitable to reseed to spring rather than leave the reduced stand of winter wheat. Eighteen treatments were used to simulate different levels of winter injury and methods of termination of t...; Download File | View full details

Impact of severe fire on ectomycorrhizal fungi of whitebark pine seedlings: Author: Trusty, Paul Evan; Date: 2009-05-15; Program: Plant Science; Abstract: Whitebark pine (Pinus albicaulis) is a threatened keystone species in subalpine zones of Western North America critical to watersheds and maintenance of high elevation biodiversity. Pine nuts are an important food for wildlife including grizzly bears. Whitebark pine stands have experienced losses up to 90% due to white pine blister rust, mountain pine beetles and replacement due to fire suppression. Active management strategies include letting natural fires burn or applying prescribed fires to clear understory fir, stimulate seedling regeneration and provide openings for nutcrackers to Plant s...; Download File | View full details
