Identifying Optimum Germination Temperatures And Analysis Weights In Seed Testing For Stiff Goldenrod (Solidago Rigida) And River Bulrush (Bolboschoenus Fluviatilis), Rachel Geary
Electronic Theses and Dissertations
Federal and state seed laws require seed lots offered for sale to be tested and labeled with the appropriate information before they can be sold. Those tests are conducted in seed testing labs all around the world. In the United States, accredited seed testing labs follow the Association of Official Seed Analysts (AOSA) Rules for Testing Seeds to provide information for labeling. The rules lack instructions for weights and germination for many native species. Stiff goldenrod (Solidago rigida) and river bulrush (Bolboschoenus fluviatilis) are two species that lack any information required for testing. When seed testing labs use correct weights …

Assessment Of Hard Red Spring Wheat Germplasm For Cold Temperature Germination Tolerance, Ulas Cinar
Electronic Theses and Dissertations
When planted early in the season, hard red spring wheat (HRSW; Triticum aestivum L.) can help for both vegetative growth and yield providing maximum agronomic productivity. The north-central Great Plains growing region is considered best for developing varieties that germinate in sub-optimal temperatures. Within limited regions, spring wheat planting typically occurs between mid-April and late May, when soil temperatures are 8 °C to 14 °C. Early season planting may result in freezing stress, while late season planting can result in heat and drought stress. Our study tested the germination rate of hard red spring wheat (HRSW) over a range of …
