Studies concerning the production of volatile oil, rhizomes and roots, to different genotypes of Valeriana officinalis L.
Valeriana officinalis L. is considered to pertain to European species, with great ecologic plasticity, which allows its adaptation to climate conditions characteristics to plain areas and also to mountain areas up to an altitude of 2400 meters. The species is a well-known curative plant, with a long history and multiple uses. Essential oils deriving from this species revealed the interest of researchers in food industry, cosmetics and officinal industry, furthermore being used as additives too.The raw material from which essential oils are being extracted is represented mainly by rhizomes and roots. This study has the purpose to emphasize the differences of essential oils production registe…
Correlations between productivity elements in Lolium perenne L. species for new varieties resistant to drought
Perennial ryegrass is considered the most important perennial gramineous plant due to the many possibilities of use (grass and fodder) [6, 9, 15].With the increasing emphasis put on increasing the area of green space, obtaining new biological forms - varieties of the main species of gramineous plants for turf, with increased resistance to drought and land during the summer, may represent an important objective of the research companies producing such seed [6, 7].In the present study, are given researches on correlations between productivity elements, obtained in an experiment that simulates conditions of severe drought soil, to different genotypes of the species Lolium perenne L., which is …
Determining the optimal sowing period at a variety from Dahlia variabilis species from Mignon group
Planted in addition to walls, to the south of the massif, in groups, beats or lawns, Dahlia beautifully decorates parks and gardens, The rebates are used especially varieties with small waist [6]. Today, when the development of green spaces is a real concern of people, we consider important to provide technology for the production of plants that can offer the widest possible variety of species with the widest possible decor period. Thus, the present article presents researches about determining the period of sowing for dwarf dahlias produced in pots, with spring and early summer flowering and used for decoration in green areas. In this experiment were taken in the account characters such se…
Characters with multiple usages- phenotypic variability analysis at Echinacea purpurea (L.) Moench species
Merging aesthetics with utility, some medicinal plants can benefit both of a high production and decoration potential. This calls for diversification of improvement directions of the species. Through this article we suggest one of these species, Echinacea purpurea (L.) Moench. This is considered to be important at this time, acquisition of new biological forms - varieties in this species, which show multiple attributes utility based on key biological characteristics, agronomic, physiological, biochemical and agrochemical (medicinal, decorative, culinary etc.). To achieve this goal, studies were undertaken, given in this article, which is the starting point for selecting characters represent…
