D. Seed pathology and vigor
E. Expression and evaluation of vigor
V. Stand Establishment
A. Effect of seed quality on stand establishment
B. Environmental factors to be considered
C. Field seeding and transplanting
D. Methodology to improve stand uniformity and emergence
1. Priming
2. Pelleting / coating

Attendance
Class attendance is mandatory and will be used as one index of student participation and subsequent student evaluation. Special circumstances necessitating absences must be arranged in advance or, in the event of an emergency, explained upon return.
Review of Current Literature
Each student will be given two papers during the semester. The student will be given 7 minutes to review the paper with the class, then 3 minutes to discuss and answer questions.
Academic Honesty
As a result of completing the registration form at the University of Florida, every student has signed the following statement: I understand that the University of Florida expects its student to be honest in all of their academic work. I agree to adhere to this commitment to academic honesty and understand that my failure to comply with this commitment may result in disciplinary action up to and including expulsion from the University.
Classroom Decorum
University policy is that beverages and food are not permitted in classrooms. No smoking and no other uses of tobacco are permitted. The University is a drug and alcohol free workplace and any student under the influence will not be permitted to participate in class activities. Cellular phones and other types of communication devices must be turned off during class (if it buzzes, beeps or rings, turn it off). Please keep reading of newspapers and other non-class materials reserved for an appropriate location such as the lounge area in this building.
UF Counseling Services
Resources are available on-campus for students having personal problems or lacking clear career and academic goals, which interfere with their academic performance. These resources include:
1. University Counseling Center, 301 Peabody Hall, 392-1575, personal and career counseling;
2. Student Mental Health, Student Health Care Center, 392-1171, personal counseling;
3. Sexual Assault Recovery Services (SARS), Student Health Care Center, 392-1161, sexual counseling; and,
4. Career Resource Center, Reitz Union, 392-1601, career development assistance and counseling.
Software Use
All faculty, staff and students at the University are required and expected to obey the laws and legal agreements governing software use. Failure to do so can lead to monetary damages and/or criminal penalties for the individual violator. Because such violations are also against University policies and rules, disciplinary action will be taken as appropriate.
We, the members of the University of
Florida community, pledge to hold our peers and ourselves to the highest
standards of honesty and integrity.
