Greenhouse Production Research Group (Toledo)
• Evaluation of polyacrylamide hydrogel as a soil amendment on growth, flowering, root morphology, and shelf life of New Guinea impatiens and pansy.
• Demonstration of silica uptake in bedding plant species and determination of its role as a nutrient and potential benefit for horticultural quality enhancement, disease and insect resistance, and moderation of micronutrient toxicities.
• Determination of critical nutrient requirements of bedding plants to achieve optimum growth, reduce nutrient levels in effluent, and to develop sensor technology for non-destructive monitoring of nutrient levels in plant tissue.
• Study the role of boron in bedding plant growth and development and identify molecular signals which can be utilized to monitor boron induced stress due to toxicity or deficiency levels in the plant.
• Determine the interaction of greenhouse cultural practices; nutrition, media composition, abiotic stresses, etc. on disease expression in bedding plant production.
