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). (Cross-listed as AGRO 824)

HORT 842BPlant Physiology3

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.

HORT 843KArboriculture3

Course Number: HORT 843K

This course focuses on the physiological principles and industry practices in the production, moving, care, and maintenance of ornamental trees, shrubs and ground covers. The purpose of this course is to provide students with the career tools to install and maintain woody plants. This goal will be accomplished through the review of the pertinent literature and through class exercises designed to improve students’ skills and knowledge of woody plant physiology, care and maintenance.

HORT 896Plant/Water Relations3

Course Number: HORT 896
