nr 1

A micropropagation method, through axillary shoot proliferation, was elaborated for Inula royleana DC. (Asteraceae), a medicinal plant native of Himalaya. Primary explants (cotyledonary node explants) and secondary explants (node explants of in vitro regenerated shoots) of the plant, inoculated on MS medium supplemented with 0.1 μM NAA and 5.0 μM kinetin, regenerated 3.4 ± 1.2 and 5.1 ± 1.9 axillary shoots per explant, respectively. The regenerated shoots were easily rooting and adapting to growth in soil.

In this study, calcium oxalate (CaOx) crystals were investigated and their morphology and distribution determined by light microscopy in tissues and organs of Inula graveolens (L.) Desf., Pulicaria dysenterica (L.) Bernh., Filago eriocephala Guss., Logfia arvensis (L.) Holup and Logfia gallica (L.) Coss. & Germ., which belong to tribe Inuleae (Asteraceae). CaOx crystals were identified in cleared organs and tissues by a histochemical technique using silver nitrate and rubeanic acid. Druses were observed in stem pith cells, leaf mesophyll cells and style cells of I. graveolens. In anther tissues, crystals were determined as styloids, and in the ovary they were identified as prismatics. No crystals were found in petal and filament cells of I. graveolens. Druse crystals were present in the filament and style cells of P. dysenterica; styloids were found in the endothecial tissues of anthers, and prismatic crystals in the ovary cells of this species. No crystals were found in petal, stem and leaf tissues of P. dysenterica. F. eriocephala and L. arvensis, and L. gallica had small prismatic crystals only in their ovaries. No crystals were observed in the other tissues of these species. This study represents additional data on the presence of CaOx crystals in Asteraceae.
