Herbaceous Perennial

Helichrysum arenarium (L.) Moench is herbaceous perennial plant belonging to Asteraceae family. The plant is well known in phytotherapy for its potential in the treatment of gallbladder disease and is classified as endangered in a number of European countries. In Bulgaria it is a protected species according to the Biodiversity Act (Annex 4) and is in the List of Species of Medicinal Plants under special regimen of conservation and use. The data on the distribution of H. arenarium in the Bulgarian flora have not been updated for more than 20 years. The aim of this study is to determine the current distribution of H. arenarium in Bulgaria on the basis of reviewing the available herbarium specimens in the Bulgarian herbariums, literature data, and personal collections. As a result, the locations of the species on the territory of the country were described and mapped. In Bulgaria H. arenarium is represented with only a few populations located in a limited area in the northeastern part of the country, in a narrow strip between the towns of Shumen and Varna.

Curcuma roscoeana Wall. is a tuberous perennial plant with tuberous rhizomes. It is an endangered species. In nature, it has a very low rate of multiplication. Propagation of C. roscoeana in vitro was done by culturing 0.5 × 1.0-mm shoot tips from young buds onto modified Murashige and Skoog (MS)+ 0.25 mg/L kinetin. Stem explants 10.0 mm in size, measured from the base of the plantlets longitudinally cut in half, were used in the experiments. The first experiment was done by varying the concentration of both kinetin and NAA, in MS liquid medium, at 0–8.0 mg/L and 0–0.05 mg/L, respectively. There were no significant differences of kinetin and NAA concentrations on the number of plantlets obtained. The 0.5-mg/L kinetin treatment gave the highest yield in number of new plantlets (3.1 plantlets/cultured explant). In the second experiment, various concentrations of BAP from 0 to 8.0 mg/l were tested. 2.8–3.7 plantlets were formed in the media with 0.05–2.0 mg/L of BAP. The most-suitable concentration of BAP was at 1.0 mg/L, providing 3.7 plantlets/cultured explants. Kinetin or BAP alone could be used in MS medium for rapid clonal propagation of C. roscoeana. The rooted plantlets could be successfully transferred into growing pots.

Abstract Zingiber capitatum is a herbaceous, perennial plant that spreads by rhizomes and possibly also by seed. It is native to India and is probably also native to Bangladesh and Nepal. It has medicinal properties and is likely to have been introduced to countries outside its native range for horticultural use. It is cultivated in Brazil and is also present in China and Vietnam. It is described as an invasive, transformer species in Cuba, but this is thought to be a misidentification. It is not listed as a weed or invasive species in any other country and information on its possible impact on habitats or biodiversity outside of its native range is lacking.

Nepeta nuda L. (syn. N. pannonica L.) is a herbaceous perennial plant that is the most widespread species of the genus Nepeta, the largest genera in Lamiaceae family. N. nuda is divided into four subspecies according to morphological differences which occur within large geographical range of distribution: subsp. nuda, subsp. albiflora, subsp. lydiae, and subsp. glandulifera. In this review, previous reports on N. nuda concerning its botanical description and systematics, phytochemistry, use in traditional medicine, pharmacology, and posibilities for other applications were summarized. All of these data indicate N. nuda as a highly promising species for application in food and pharmaceutical industries, as well as in agriculture for the development of natural pesticides.

Classical growth analysis is interpreted in the context of perennial plant growth. The inter­pretation was prompted by a long-term field experiment on apple; infrequent tree samples and the deciduous nature of apple prevented the simple quantification of growth relative to the plant’s biomass. Absolute growth rates are related to the mass of the dormant tree and from this evolves an analogue of the leaf/plant mass ratio as used in the growth analysis of annual plants.
