Lecture schedule (Spring 2008)

Lab schedule (Spring 2008)

Library reserve (eReserve, Spring 2008)

Instructor: Dr. Loren Stephens, 127 Hort, 4-1917, lcs@iastate.edu

Room locations: The lecture period will be in room 118. Lab sections A and B will meet in room 160.

If you have a disability and require accommodations, please contact the instructor early in the semester so that your learning needs may be appropriately met. You will need to provide documentation of your disability to the Disability Resources (DR) Office, located on the main floor of the Student Services Building, Room 1076, or phone 515-294-6624.

Course objectives: First, to become familiar with the principal methods employed in plant propagation and their uses in horticulture. Secondly, to understand the underlying principles that allow these methods to be successfully used. Thirdly, to gain some practical experience in plant propagation.

Desired learner outcomes (what you should be able to do at the end of the semester):

Describe the specific methods of vegetative and seed propagation and identify which method is best under a wide variety of circumstances.

Synthesize the elements needed for success of each specific vegetative/seed propagation method and compare the advantages and disadvantages of using one method over another.

Recognize and apply the proper way to take and stick cuttings, plant seeds, graft and bud plant parts together into one growing plant, and multiply plants by tissue culture, division, and specialized structures.

Analyze the results of laboratory projects and predict the number of plants that can be propagated based on the amount of starting materials and the type of propagation method used.

Lecture text: The text (Hartmann et. al, 7th edition, 2002) is available at both the University Bookstore and the Campus Bookstore. A complete listing of suggested reading for each lecture is available in the appendix of the lab manual.

Reserve reading: One copy of Hartmann, 7th edition will be placed on Library Reserve. Other materials may be added to Reserve during the semester. Reading assignments from Reserve materials may be covered on lecture exams. An electronic copy of the lecture notes and last year's exams will be placed on Reserve.

Lab projects: Lab periods will be used for lab projects, which are described in the lab manual. The lab manual is available from the University Bookstore or from Campus Bookstore. The purpose of the lab manual is to guide you in completing the lab projects, to allow you to take notes during the semester on each lab project, and to help you keep detailed records of important dates and data collected. Students will be expected to take notes and keep records of their lab projects. At various times throughout the semester, data from these projects will be collected and all students will be held responsible (on the lab practical exam) for the data collected from these projects. Students who may miss a lab period for some unavoidable reason (illness, weather, etc.) should make arrangements with another student to cover for them (e.g., starting a project, checking on projects in progress, etc.). Because of the number of students and the organization of the lab projects, it isn't always possible to make up missed labs; that is, much of the plant material can't easily be held from week to week.

Greenhouse watering of lab projects: Students will be expected to water their own plant material throughout the semester. The greenhouse crew will water plant material on the weekends (Sat., Sun., holidays) only when plants show water stress symptoms.

Lecture and lab grading. Lecture exam dates (for the 3 lecture exams) are listed in the lecture schedule. Students who do not take the third lecture exam on the scheduled date may elect to take it during the final exam time (see http://www.iastate.edu/~registrar/exams/). A lab practical exam will be given toward the end of the semester, which will cover the entire semester, will be heavily weighted on material from lab projects, but may cover some material from lecture and/or text. Lecture exams may also cover material from both lecture and lab. All regularly scheduled exams will be objective (multiple-choice, true-false, or matching), machine-graded, and worth 100 points. Some questions may also require written responses. The 4 exams will total 400 points, with the final percentage (%) rounded to the nearest whole number. Grades will be assigned at the end of the semester, based on the percent of the total points: greater than or equal to 90% = A- to A, greater than or equal to 80% = B- to B+, etc. (but see below for +/- policy). Depending on total class performance, these percent "boundaries" may be lowered (e.g., 88% may earn an A-), but they will not be raised; i.e., a student earning 90% as a final course score will be guaranteed to earn at least an A-. Plus/minus grading will be used as follows: 3 points from the final score "boundary" will earn a "+" or "-". For example, if the A/B boundary is 90%/89%, a student earning 90% will earn an A-, while another student with an 89%, 88%, or 87% will earn a B+.

Make-up exams: Students should make every effort to take each exam at its scheduled time. If a make-up exam is necessary for lecture exams 1 or 2, the time/place for the make-up exam will be announced during the lecture period, either before or after the regularly scheduled exam.
