Wide range of consulting experience in horticultural crops and products. Emphasis has been in environmental effects on genetic expression in greenhouse-cultivated plants such as chrysanthemums, poinsettias, Easter lilies, African violets, Cyclamen, Roses, selected herbaceous perennials, and numerous flowering annuals. The range of applications include conventional and tissue culture propagation, plant growth regulating substances, fertilizers, growing media, natural and synthetic mulches, and pesticides. Investigations have been conducted in the response of vegetables [tomatoes, peppers, and cucumbers] to hydroponics conditions. Current involvement in the effects of nutrients and pH on yields in essential oil producing species. Previous and/or on-going projects, all aimed at solving specific growing, production, or cropping problems lend support to both commercil and educational institutions. Devising a method for identifying superior genotypes among soft pines, elucidating a quick test method for determining the level of air and moisture in commercial growing media, determining the feasibility of using spent compost as a growing medium for greenhouse-produced crops, evaluation of a naturally occurring pesticide as an effective method for control of insects on floricultural and ornamental crops, and the establishment of a protocol for the tissue culture propagation of selected oil-producing plants are among recent projects.
