Abstract
Various representatives of Eleutherococcus from Asia are important medicinal plants, vegetables and ornamental plants. Possibilities of vegetative propagation were presented and structural investigations were carried out in the present work.
The vegetative propagation took place via head and part cuttings in sand or peat and is dependent on species. The addition of 1000 ppm indoleacetic acid increase the rooting rate of cuttings. Beside of vegetative propagation plants can also grow from adventitious shoots of rooted leaves of Eleutherococcus gracilistylus. A irradiation of leaves with red light stimulate the development of adventitious shoots.
Farther Eleutherococcus species can develop different long adventitious roots from leaves and pinnate leaflets in tap water and sand. This process is dependent on species.
A plant tissue culture of Eleutherococcus sieboldianus was successful established in another experiment on propagation. Somatic embryoids develop from callus of surface sterilised leaf explantates growing up to plants in their further development. Furthermore a specific microflora was discovered in rhizosphere and root hairs.
The mycorrhiza of analysed Eleutherococcus species is a vesicular-arbuscular mycorrhiza (VAM). The structural type of this mycorrhiza is a Paris-type. Leaves of Eleutherococcus gracilistylus inoculated by Glomus intraradices are characterized in their mycorrhiza as Paris-type.A further characteristic is the existence of intraradical glomerospores in adventitious roots.
Molecularbiological investigations on root associated Glomeromycetes arised that representatives of the genus Glomus group A colonise the roots of various Eleutherococcus species from outdoor.
In vitro experiments with germinated spores of Gigaspora margarita show a negative gravitropism of various fungal hypha. A colonisation of in vitro propagated plants of Eleutherococcus sieboldianus is possible with this glomeromycete.
The inoculation experiment of Eleutherococcus sieboldianus and Glomus intraradices resulted in reduced shoot mass respectively no differences in total weight of inoculated plants in comparison to control. Moreover all mycorrhizated plants were yellow colored.
