In the ovary epidermis of Ornithogalum umbellatum L. lipotubuloids were found, i.e. distinguished cytoplasmic domain with an agglomeration of half unit membrane-surrounded lipid bodies, entwined and held together by a system of microtubules (Protoplasma 75: 345-357; 77: 473-476). Using light and EM-autoradiography with 3H-palmitic acid (25 μCi/ml) it was found that lipotubuloids were the site of intense incorporation of this isotope. After extraction of lipids with lipid solvent the lipotubuloids were not labeled. Localization of autoradiographic grains after 15-h postincubation with isotope-free medium indicated a migration of the labeled substances from the lipotubuloids to the whole cells. Ultrastructural studies demonstrated that most autoradiographic grains after 2-h incubation were localized over the site of the microtubules adjoining closely the half unit membranes of lipid bodies. These observations suggest, that the surface of lipid bodies may be the active site in lipid synthesis and involvement of the microtubules in these processes is possible.

"Elaioplasts" observed in Vanilla planifolia, Funkia Sieboldiana and Althaea rosea exhibit all the features characteristic of lipotubuloids earlier described in Ornithogalum umbellatum. They are cytoplasmic domains containing aggregates of lipid bodies connected with microtubules. The immunogold technique confirmed the presence of tubulin in this domain. These structures do not have their own membranes but they are surrounded by a tonoplast at the side of a vacuole since they invaginate into it. In cytoplasm of this domain among lipid bodies there are numerous ribosomes, ER cisternae and vesicles as well as few mitochondria, Golgi structures and microbodies while at older developmental stages there are also autolytic vacuoles. The fact that they are so similar to O. umbellatum lipotubuloids suggest that "elaioplasts" of V. planifolia, F. Sieboldiana and A. rosea can also be named lipotubuloids.

Microscopic analysis of embryogenic tissues of Picea abies and P. omorika showed that the tissues differed in proportions of various types of proembryogenic masses, and in presence/absence of early somatic embryos, which suggests that they differed in embryogenic potential. On the basis of this study, embryogenic competence of tissues can be assessed at early stages of somatic embryogenesis, and thus the most efficient lines can be selected (one Picea abies and two P. omorika). In the course of development of somatic embryos embryogenic tissue was placed on a medium with abscisic acid (ABA), which affects an increase in osmotic pressure at the stage of maturation of somatic embryos and finally on the regeneration of cotyledonary embryos. In this stage of embryos development, storage materials were accumulated, which are used in specific metabolic processes during embryo development.
