The 4-H Leathercraft project will help members:
- Learn about the history, selection, care and value of leather.
- Develop physical coordination and muscular dexterity.
- Develop skill and creative talents.
- Make useful and attractive articles of leather.
- Learn to work cooperatively with others.
- Learn a constructive...
As a 4-H leader and educator, you are in a position of great power—that is, the positive power to encourage young people to succeed. As a volunteer leader, you can channel their curiosity, inspire new interests, and continually offer new opportunities for them to grow and develop into happy and...
Stratified seeds of coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) were germinated, sown in soil, and seed coats and megagametophytes were removed at various stages of early seedling development. Yield and quality of DNA extracted from the megagametophytes were related to several morphological traits of the seedlings after
2...
Chemical and microbial soil properties were assessed in paired unfertilized and urea fertilized (>89 g N·m–2) plots in 13 second-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands distributed throughout western Washington and Oregon. A decade following the termination of fertilization, fertilized plots averaged 28% higher total N in the O layer...
Riparian ecosystems, through their unique positions in the agricultural landscape, have the potential to mitigate nutrient loading to streams. This study was conducted to gain a better understanding of N cycling in a poorly drained Grass Riparian Zone (GRZ) and adjacent Perennial Ryegrass seed Field (PRF) in the Willamette Valley,...
The effect of heterozygosity on the phenotypic stabilities of six
morphological plant characteristics was studied in hybrid crosses of
two self-pollinated barley species Hordeum vulgare L., emend Lam.
and Hordeum distichum L., emend Lam. Experimental material
consisting of parents and their F₁ diallel progeny were grown at two
field locations...
Sorbitol-induced osmotic stress (SIOS) to the root was found to be effective in
reducing transpirational water loss in plants during water stress. Mechanisms of SIOS in
stomatal control were investigated in containerized apples (Malus domestica Borkh.
'Gala'/M26) when leaf water potential (Ψw), osmotic potential (Ψs), turgor potential (Ψp),
stomatal conductance...
Most of the policy debate surrounding the actions needed to mitigate and adapt to anthropogenic climate change has been framed by observations of the past 150 years as well as climate and sea-level projections for the twenty-first century. The focus on this 250-year window, however, obscures some of the most...
