More than 14,000 ornamental research trials have been conducted in this program since 1977. This extensive research program has led to more than 4900 label registrations for fungicides, herbicides, insecticides, nematicides, and plant growth regulators. During 1996 alone, 890 ornamental label registrations were obtained. This cooperative program is conducted by federal and state workers in cooperation with the green industry,including growers of floral, forestry, nursery, and turf crops. Registrations are also developed for the commercial landscape and the interior plantscape.

Experimental Model System

The influence of 24-epibrassinolide on the efficiency of regenerants obtained from embryonic calli formation was studied in wheat cultivars contrast for drought resistance. The possibility of using the experimental model system «immature embryo – embryonic callus – regenerant» in the rapid assessment of the effect of antistress plant growth regulators is shown.

Appreciable Variation

The influence of stage of fruit development and plant growth regulators on somatic embryogenesis and the relation of cultivar response on somatic embryogenesis and subsequent plant development have been investigated in eight cultivars of pecan [Carya illinoensis (Wangenh.) C. Koch]. Explants from the micropylar region of the ovule were more embryogenic when removed from fruits in the liquid endosperm stage than were intact ovules from less-mature fruits or from cotyledonary segments of more-mature fruits. Explants conditioned on medium containing auxin alone or auxin + cytokinin produced more somatic embryos than medium containing cytokinin alone. Under the conditions of this study, frequency of embryogenesis, as well as the germination of somatic embryos leading to plant development, indicated appreciable variation among cultivars. Plant development was greatest by far from somatic embryos of `Schley' than other cultivars studied.
