Project Description
The current project aims to develop a protocol for optimizing germination rates in the popular Christmas tree seeds. Oregon produces approximately four million Christmas trees, contributing to about 30% of the nation’s supply. The Christmas tree program at OSU has selected elite exotic Christmas tree species that tolerate both abiotic (heat, drought) and biotic stressors (pests, diseases). Seed orchards for these two species have been established by the program to provide a continuous supply of seeds to growers. Two popular exotic species in the Pacific Northwest are Turkish fir (Abies bornmulleriana) and Nordmann fir (A. nordmanniana). However, there is a limitation on seedling supply. Additionally, seed storage longevity is relatively short: two to three years, compared to other species. This project focuses on identifying families (different genetics) of these two species with higher germination rates. Project outcomes will contribute to the long-term goals of the Christmas tree program.
Describe the type of work and tasks you anticipate the student will perform
The student will clean seeds collected from Turkish and Nordmann firs with different genetics. The cones have already been harvested. The student will evaluate variable seed parameters to test germination rates among different genotypes. These tasks will include assessing moisture content, using the tetrazolium test for seed viability, and conducting germination tests. In addition, the student will have an opportunity to help with developing outreach material and entomology skills.

How many hours per week do you anticipate a student to work?
10-20
How many hours per week do you anticipate engaging in direct mentorship?
1 - 2 hours
The goal of my mentoring plan will be to provide guidance in accomplishing the project goals and to develop technical and professional skills to excel both within and outside the school. To accomplish this goal, my mentorship plan will include weekly meetings, written reports, and poster presentations during the symposium. The student will also have an opportunity to be creative to accomplish the project goals.
