1 Daniel Ivan Leskovar PERSONAL INFORMATION Rank Professor, Vegetable Physiology Horticulture Affiliation Texas A&M AgriLife Research & Extension Center at Uvalde Telephone (830) ext. 140 (wk) (830) (cell) EDUCATION Universidad del Comahue, Argentina, B.S., Horticulture University of Wageningen, Holland, Graduate Training University of California, Davis, MS., Vegetable Crops, 1986 University of Florida, Ph.D., Vegetable Crop Physiology, 1991 WORK EXPERIENCE Assistant Professor, Vegetable Physiology, Texas A&M University Associate Professor, Vegetable Physiology, Texas A&M University Professor, Vegetable Physiology, Texas A&M University Assistant Director- Vegetable and Fruit Improvement Center Center Director, Texas A&M AgriLife Research, Uvalde RESEARCH The program is centered in the identification and understanding of plant morphological and physiological adaptation mechanisms to environmental stresses and in the development of sustainable vegetable production systems. Traditional crops under investigation include spinach, onion, carrots, muskmelons, watermelon, and tomato. Specialty crops include sweet and hot peppers, artichokes, western shipper melons, leafy greens and strawberry. The research emphasis is on: 1) seed-transplant production and physiology to increase plant survival under drought stress; 2) signaling compounds (abscisic acid - ABA, ethylene and inhibitors AVG, 1-MCP) to modulate seedling, plant and fruit growth, 3) root and shoot developmental responses to water conservation strategies and drip/center pivot irrigation systems, 4) protected cultivation - high tunnel and hydroponic systems, 5) phytochemicals and sensory attributes related to season, deficit irrigation, nitrogen, and plant populations, and 6) genotype selection and development for drought resistance, high yield, water use efficiency, and quality.
