Water Deficits

This paper briefly reviews the current developments on the role of leaf hydration on leaf growth and photosynthesis and concludes that changes in growth and stomatal action are not always closely correlated with changes in leaf hydration. A case is developed for soil and root water relations affecting leaf growth and stomatal function, and a role for plant growth regulators is postulated. The influence of this changed perspective on the adaptation of plants to water deficits is discussed. In particular, the importance of the adaptation of roots to water deficits is highlighted and the need for more studies on the interaction between the shoot and the root is emphasized.

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.
