In embryos and cotyledons of seeds of the radish cv. `Tetra Iłówiecka' (which needs 20 days of vernalization) and cv. 'Saxa' (which flowers without vernalization) germinating at a vernalizing temperature of 5°C, the levels of auxins, gibberellins, cytokinins and the aibscisic acid-like inhibitor were determined, The analyses were performed after 5, 10, 15, 20, 25 and 30 days of chilling. The levels of growth regulators were also determined in embryos and cotyledons of seeds germinated at 260C when in the same growth stage as the material taken from chilled seeds. Cold treatment significantly affected the level of all endogenous growth regulators in embryos and cotyledons of both varieties. However, changes in the levels of these substances were not directly connected with the vernalization process. It was found that the vernalization of seeds of 'the radish cv. `Tetra Iłówiecka' increased the level of GAs in leaves, this did not, however, coincide with flower initiation. It is concluded that the role of GAs in flowering of the studied plants is connected rather with photoinduction than with vernalization.

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.
