This program is offered through Ag*IDEA, a national consortium of universities offering online programs and courses in agriculture disciplines. Students apply and are admitted at one university; enroll in all courses at that university and graduate or receive a certificate from that university. The online courses are taught by the best faculty in the discipline from several universities within the consortium.
Ellen Paparozzi’s key areas of focus are plant physiology (plant nutrition) and anatomy, floriculture and ornamental horticulture and plant physiology and production ecology. Her main research focus is on the broad topic of leaf yellowing and subsequent re-greening of leaves. She is approaching this topic using physiological, anatomical and molecular biological methods. She teaches several courses and has published numerous articles.

|Plant Nutrition and Nutrient Management||3|
Course Number: HORT 824
(AGRO 824) Macro- and micronutrient elements and their function in the growth and development of plants; the role of single elements; interaction/balances between elements and nutrient deficiency/ toxicity symptoms as they affect the physiology of the whole plant; and the relationship between crop nutrition and production/environmental considerations (e.g. yield, drought, temperature, pests).
Course Number: HORT 842B
Presents fundamental concepts underlying the science of crop physiology, including crop phenology, canopy development and light interception, photosynthesis and respiration, and dry-matter partitioning.
|Floral Crops Production||2|
Course Number: HORT 842E
The principles and commercial practices for producing floral potted crops and cut flowers, emphasizing the physical responses of plants to their environment. Aspects of post-harvest physiology will be covered.
|Water Issues in Lawn and Landscape||3|
Course Number: HORT 842J
Examines critical water issues related to irrigation in urbanizing watersheds, with an emphasis on water quality and quantity. Factors impacting water scarcity and quality will be discussed. Course will help students understand the interrelatedness of correct irrigation practices and water quality/quantity, and will equip them with the necessary career tools to help protect water resources through application of science-based irrigation practices.
|Greenhouse Crop Production||4|
Course Number: HORT 843A
