Abstract:

The aim of the present study was to study success and development of coniferous trees for the needs of intensive plantations for biomass production, used in the recultivation process of mine-spoilt banks of opencast mines in the Kolubara basin. For this purpose, an experiment with European larch seedlings, aged 2+0, which lasted for four years in plots with seven repetitions was set. The distance between the rows with the seedlings was 1 m, and 2.5 m between the plants in a row. Out of the initial 1,000 seedlings 90.5% and 77.4 % survived in the first and second year after planting, respectively. At the later stages, the decay of the plants almost stagnated (up to 74.8%). From autmn 2007 to spring 2010 total height increment of seedlings was 1.17 m. Total root collar diameter increment was nearly1.9 cm. The highest increment was reported during the last vegetation of seedlings (in spring 2010): diameter increment was about 1.2 cm and height increment was about 0.9 m.
Differences between seedlings from sludge treated and untreated, control deposols (measured in spring 2010), were significant. Treated seedlings showed better results in mean root collar diameter as well as in mean height of seedlings (2.5 cm and 1.7 m, respectively) in comparing with untreated (control) ones (1.9 cm and 1.0 m, respectively). The results obtained justify the future more intensive establishment of plantations of this fast-growing conifer species. European larch also appears to be suitable for growing on mechanically damaged substratum.

Abstract:

Vertical gardens are a special type of interior phytodesign, getting more and more popular in the world landscape practice. They are specific arrangements of ornamental plants created in the exterior as well as in the in-door spaces, forming a self-maintaining system. In the interior the most appropriate and commonly used are the epiphytes. Principles of nutrition and their requirements to the environmental conditions are prerequisites for a successful use in the vertical gardens. In specialized collections and sales network in our country, that offer a variety of ornamental epifitytes, the plants are used and often treated as terrestrial plants. This article presents an analysis of the species composition of epiphytes in real world models of vertical gardens and the assortment of such species kept in collections or commercially available in our country. A survey on the diversity of imported and grown epiphytes carried out in June-September 2009 is presented. Totally 10 sites are audited (9 commercial garden centres and also the greenhouses of the Institute of Ornamental plants - Negovan).

Abstract:

Surface and canopy fuel characteristics that influence the initiation and spread of wildland fires were measured in representative Black pine (Pinus nigra) plantations in Southern Bulgaria. Potential fire behavior (type of fire, probability of crown fire initiation, crown fire type, rate of spread, fire line intensity and flame length) in Black pine plantations was simulated with the most updated fire behavior models. The probability of crown fire initiation was high even under moderate burning conditions, mainly due to the low canopy base height and the heavy surface fuel load. Assessment of surface and canopy fuel characteristics and potential fire behavior can be useful in fuel management and fire suppression planning.
