Synthetic Approaches

A new synthetic approach is described to the plant growth regulators of the hexahydrobenzo[e]- 1,2-dioxin group (the G-regulators of Eucalyptus grandis). Condensation of 1,3-diketones with aldehydes under Lewis acid catalysis gives, in good yield, the 1 : 2 adducts (4H-1,3-dioxins); these are simultaneously cleaved and (with some exceptions) oxidized on silica gel to the desired structure. In this way synthesis of a number of G-regulator analogues of similar physiological activity has been achieved.

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.
