M.S., Floriculture & Ornamental Horticulture, Cornell University, Ithaca, NY, 1978
Ph.D., Floriculture & Ornamental Horticulture, Cornell University, Ithaca, NY, 1980
Areas of Focus
- Plant Physiology (plant nutrition) and Anatomy
- Floriculture and Ornamental Horticulture
- Plant Physiology and Production Ecology
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 floricultural and ornamental plants, and the execution complex plant nutritional experiments. We will train undergraduate and graduate students in sectioning and embedding plant material for light and fluorescence microscopy.
The laboratory technologist is Liz Conley, M. S. She coordinates all efforts in the laboratory and is responsible for equipment training, lab procedure training and equipment check-out. The lab is located in Rm.384 Plant Sciences and Liz can be be contacted at 2-2850 or via email at firstname.lastname@example.org.
Our main research focus is on the broad topic of leaf yellowing and subsequent re-greening of leaves. We are approaching this topic using physiological, anatomical, and molecular biological methods.
Our current project right now involves Swedish ivy (2 species) and its ability to re-green after macronutrient and micronutrient deficiency. We have worked out re-greening timetables; protocols for protein separation by 2-D gel electrophoresis and total carbohydrate analysis also. We also view these symptoms utilizing light, fluorescence, confocal and electron microscopy.
Applied Research - Strawberries in Winter - sustainable horticulture
Research is underway to determine which cultivars of strawberries would grow best in the greenhouse during the winter. In order to do this, we are taking data on number and weight of berries per pot, nutraceutical characteristics and stolon production as well as light and moisture levels. Estimations of start-up costs for a poly greenhouse and costs of production are also part of this project. Collaborators on this project include: Dr. George Meyer, Biological Systems Engineering; Dr. Vicki Schlegel, Food Science; Dr. Erin Blankenship, Statistics; Dr. Paul Read, Horticulture; Associate Professors of Practice David Lambe MBA and Stacy Adams, M. S., and Ms M. Elizabeth Conley, MS, technologist. Please visit our website at agronomy.unl.edu/cea for more information.
