Ellen T. Paparozzi


Area of Expertise: Horticulture

B.S., Plant Science, Cook College, Rutgers University, 1976

M.S., Floriculture & Ornamental Horticulture, Cornell University, Ithaca, NY, 1978

Ph.D., Floriculture & Ornamental Horticulture, Cornell University, Ithaca, NY, 1980

Area of Focus

  • Plant nutrition and plant anatomy; medicinal plants

Research Interests

The purpose of our lab is to offer training to graduate students (and upper division undergraduate students) in research methods that involve the growing of horticultural and agronomic plants, and the execution complex plant nutrition experiments. We also train undergraduate and graduate students in sectioning and embedding plant material for light and fluorescence microscopy.

Major Project Activities

Controlled Environment Agriculture – whether it's sustainable growing of fruit or medicinal plants in a greenhouse during the winter or identifying nutrient deficiencies using hydroponics, our lab does it! We currently are reviewing all our leaf re-greening after nutrient deficiency efforts to determine our next steps.

On-going projects include winter production of basil for herbage and essential oil as well as identifying nutrient deficiencies across basil varieties. We are also investigating the anatomical origin of oil trichomes on 18 cultivars of basil (pesto and specialty) to determine if size, presence and frequency are related to essential oil production.

Future plans will involve post-harvest physiology of strawberries with a focus on new uses for American's favorite fruit.
