Özet

This Study investigated the effects of dungpat thicknesses and water regimes on the emergence, shoot development, and survival of seedlings of bluebunch wheatgrass [Psuedoroegneria spicata (Pursh) A. Love], Sandberg bluegrass (Port secunda L.), and Hycrest crested wheatgrass [Agropyron desertorum (Fisch. Ex Link) Schult. X Agropyron cristatum (L.) Gaert.]. Pre-germinated seeds of each species were planted separately in the center and periphery of artificially prepared dungpats at heights of 0.5 cm for 1 cm thick dungpats, 0.5 and 1.5 cm for 2 cm-thick dungpats, and 0.5, 2.0, and 3.5 cm for 4 cm-thick dungpats. In order to simulate natural drying conditions in the soil profile half of, the replications for each dungpat treatments received Supplemental water, while the other half received no supplemental water during the study. Seedling emergence, development, and Survival for all species were greatest when seeds were planted 0.5 cm from the bottom of dungpats and planted in 1 cm-thick dungpats. Supplemental watering enhanced seedling emergence and survival for all species. Hycrest crested wheatgrass had a greater seedling emergence than bluebunch wheatgrass and Sandberg bluegrass; and Hycrest crested wheatgrass and bluebunch wheatgrass had a greater seedling survival than for Sandberg bluegrass.

This study investigated the effects of dungpat thicknesses and water regimes on the
emergence, shoot development, and survival of seedlings of bluebunch wheatgrass
[Psuedoroegneria spicata (Pursh) A. Love], Sandberg bluegrass (Poa secunda L.), and
Hycrest crested wheatgrass [Agropyron desertorum (Fisch. Ex Link) Schult. X Agropyron
cristatum (L.) Gaert.]. Pre-germinated seeds of each species were planted separately in
the center and periphery of artificially prepared dungpats at heights of 0.5cm for 1 cmthick
dungpats, 0.5 and 1.5 cm for 2 cm-thick dungpats, and 0.5, 2.0, and 3.5cm for 4 cmthick
dungpats. In order to simulate natural drying conditions in the soil profile, half of
the replications for each dungpat treatments received supplemental water, while the
other half received no supplemental water during the study. Seedling emergence,
development, and survival for all species were greatest when seeds were planted 0.5cm
from the bottom of dungpats and planted in 1 cm-thick dungpats. Supplemental
watering enhanced seedling emergence and survival for all species. Hycrest crested
wheatgrass had a greater seedling emergence than bluebunch wheatgrass and Sandberg
bluegrass; and Hycrest crested wheatgrass and bluebunch wheatgrass had a greater
seedling survival than for Sandberg bluegrass.
