The Anatomical And Morphological Effects Of Dcpa On Seedlings Of Selected Species Of Plants, Bijan Shaybany
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Seeds of oat, green foxtail, squash and tomato were germinated in soil treated with different levels of DCPA (dimethyl 2, 3, 5, 6-tetrachlorote-rephthalate). The concentrations used varied according to the sensitivity of the plants to the chemical.
The response of oat and foxtail to DCPA was similar. The growth of booth root and shoot was reduced. This reduction was directly related to the concentration of DCPA. Anatomical studies showed that cells in the shoot and root meristems of treated plants were completely disarranged and that some of the cells of these regions were hypertrophied. Some clumping of nuclei was observed …
Microenvironmental Effects Of Erosion Control Treatments On Seedling Survival In A Southeastern Utah Salt Desert Area, Ross W. Wein
Microenvironmental Effects Of Erosion Control Treatments On Seedling Survival In A Southeastern Utah Salt Desert Area, Ross W. Wein
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A study of the microclimate of erosion control treatments was carried out in two habitat types in a semiarid southeastern Utah, salt desert shrub area. The soils are highly eroded Mancos shale and support a low density of salt desert shrub species which offers little protection against high intensity summer convectional rainstorms.
Gully plugs and contour furrows had been installed by the Bureaus of Reclamation and Land Management to prevent runoff of soil laden water which results from these summer rainfalls. Formerly this sediment was carried to the Colorado River and deposited in Lake Powell.
The purpose to t he …
