This research examines the influence of soil on spruce from the biometrical and auxological point of view, highlighting the correlation between soil and vegetation. The researches have as subject the stands being at the same altitude, climatic and vegetation conditions, but which were developed on different soils. Objectives of the research were pursued to establish a relationship between the type of soil and biometrical and auxological characteristics of the forest vegetation. The research was developed in Cindrel Mountains, Rasinari Forest District and Oncesti District. On experimental areas the forest vegetation was full inventoried and determinations of physical and chemical properties of the soil were made. Biometrical and auxological calculations on trees have targeted the following characteristics: diameter, height, growth rate and some quality indicators. The soil has been study from the main characteristics point of view, as ecological determinants: pH, degree of saturation in bases, skeletal content, and physiologically useful volume. It has been also made observations on the indicator flora and forest site reliability. The results, collected from the experimental area and statistically processed were presented in tabular form and the biomitrie and auxologic indicators were represented in graphics for a better expressiveness. The results analyses conduct to conclusions regarding suitability of soils for forestry vegetation. At the same time, the soil type influences directly the characteristics of forest vegetation, leading to significant difference of biomitrie and auxologic indicators. [ABSTRACT FROM AUTHOR]

The multiple usages of Angelica archangelica L. species are given by its medicinal properties due to high content of essential oils and also, aromatization capacity which makes it useful in the food industry to flavor their various additives or alcoholic beverages, its habitus is highly appreciated for its ornamental value. The major problem of this species is that the number of individuals from spontaneous flora decrease dramatically in the past 40 years, being included on the red list of protected species. Thus, we consider important at this stage any study action to improve the conservation methods in situ and ex situ and to enrichment the collection of genetic resources in order to broaden them. For these reasons this paper presents analysis of the principal components of the inflorescence, in order to select some high performing genotypes, either in terms of decor can be encouraged to spread their green spaces, whether in terms of seed production to increase cultivated areas.

Evaluation of drought tolerance of individual genotypes showed the existence of a significant genetic variability within populations / varieties. However, it was found that a mixture of varieties may have a different response on resistance to drought compared with the reaction of varieties that make up. (Sojka, 1984). Rapid regeneration ability of plants that occur after the rain after a long period of drought is often correlated with the ability ridcatā production during droughts and is a character that can be easily determined (Abraham et al., 2004). Given that the focus is increasingly on improving areas of green spaces, to obtain new biological forms - varieties of the main species for turf grasses, with greater resistance to drought may be an increased objective of the research companies producing seed this way. Thus, the present paper, are presented research on drought response testing, a species of grasses, which represents the ideal partner for simple and complex mixtures of grass. [ABSTRACT FROM AUTHOR]
