The study was carried out on three ornamental varieties of Ipomoea batatas ('Heart Bronze', 'Black', 'Heart Lime') grown in the field and in pots. Four types of substrate were used for pot culture: garden soil + peat, garden soil + peat + hydrogel, garden soil + peat + coconut fiber, garden soil + peat + coconut fiber + hydrogel. In field conditions, the plants from the three varieties were distinguished by a larger size than in the pots. Also, in the field, the higher degree of stem branching was recorded in 'Black' and the longest branches in 'Heart Lime'. The substrate garden soil + peat favored the length of the branches in all the varieties studied. The garden soil + peat + hydrogel at 'Heart Lime' and the garden soil + peat + coconut fiber at 'Heart Bronze' had a positive effect on the degree of branching. The use of twofactor ANOVA analysis indicates a strong influence of both the variety and the cultivation system on the morphological characters analyzed. [ABSTRACT FROM AUTHOR]

Paulownia is the fastest-growing tree species in Romania compared to other dendrological species. The development of this species for commercial purposes can be achieved in 4-6 years if certain pedological, agrochemical, and agrotechnical factors are respected, along with specific maintenance work. This study analyzed two hybrid varieties: Paulownia 'Cotevisa 2' and Paulownia 'Superhibrid Z 07'. The establishment and maintenance work, as well as the growth evolution of these varieties, were monitored. The main objective is to obtain data that contribute to the success of Paulownia cultivation in Romania, due to the lack of information regarding the cultivation and maintenance of this plant.

Among the multitude of dendrological species with high decorative value, Albizia genus is of particular importance in the landscape design especially in the conditions of our country which are generally favorable and very favorable for the growth of these species. The purpose of the present work is to highlight the ornamental potential of the best known species of Albizia genus. Albizia julibrissin Durazz. seeds were used for the experiment. Propagation of this species can be done quite easily by seeds, provided that the pods are harvested in October and the sowing is done in the spring (Sandu, 2009). Observations were made regarding the evolution in different periods of the vegetation, aiming the development regarding the germinability, growth and development of seedlings under the action of some rooting regulators, namely Radi-Stim Nr. 2, Asfac-4 25 ppm and Asfac-4 20 ppm. The variants treated with these regulators had a particular importance on seed germination, in terms of a deeper rooting, resulting in much more vigorous plants. [ABSTRACT FROM AUTHOR]

Old apple cultivars, either originating from Romania or of foreign origin but grown widely in this region, were examined to provide a characterisation of the varieties. The aim of the thesis was to observe and evaluate the phenological, and morphological traits of the old apple cultivars using the following methods as: observation of flowering phenology traits and the classification of the cultivars into flowering time groups; characterisation of the gene bank collection and the determination of diversity using morphological markers; preparation of a number-coded characterisation based on the morphological and biological traits laid down in the UPOV guidelines. Identified and collected material provides the initial genetic source for variety improvement. Using the observations and determinations made, we identified the potential genitors for different useful characteristics that we used in controlled intra and interspecific hybridizing. Researchers constant concern refers to preserving, coplotting, periodically reorganizing and assessing the biological and agrochemical characteristics of each genotype, the exchange of biological material into the restricted manner and the assessment of the potential genitors for some useful characteristics used in genetic breeding programs.

Green roofs are a way of landscape development that combines aesthetics with ecological functions of these types of facilities. The sustainability of this approach lies in combining economic, aesthetic and especially functional, making them the primary aspects anchored in determining the choice of the most suitable crop systems. Romania is an European country where culture tree species with ornamental value is well represented by a great diversity of species and varieties that are favorable climatic conditions for growth and flowering, while ensuring décor staggered throughout the year. A difference from the landscaping from the ground is that the arrangements of roofs and terraces rarely work with plants decorative through flowers, such as the use of tree species is more than appropriate in this case. Extending the concept of Green Roof has advantages in terms of encouraging environment, educational system and the community life, fostering solidarity population to achieve a framework for proper management of long-term spaces. Implementing the concept of green roofs in public areas can be very successful, both in the short and long term, primarily by reducing pollution and improving the aesthetics of such spaces furnished. Diversification research in this area and finding new techniques for obtaining more efficient and rapid production of a higher quality is one of the current priorities of food safety programs.

The idea of rehabilitation proposed in the present project presented in this paper aims primarily to capitalize on green spaces in the park located in downtown Buhusi, increase the area of land legally framed as green space, giving up some parasitic elements such as basketball court on the territory park, increased accessibility and the creation of the best conditions to cover the need for relaxation, culture and education of all categories of population without discrimination. The rehabilitation solution proposes a completely new architectural concept with landscape elements - defining the organic style. The arrangement scenario consists of free, sinuous shapes meant to create a harmonious, balanced rhythm and to strengthen the feeling of space. The interior of the proposed rehabilitation solution is intended to provide a gradual transition between the various functional areas of the park. The vegetation will consist of small shrubs and conifers arranged in clusters that grow in decorative terraces throughout the year. The arrangement of deciduous and coniferous trees will be made so that the colour offered is diverse in all seasons. [ABSTRACT FROM AUTHOR]

The genus Crocosmia, from the Iridaceae family, includes the plants with obvious potential both for garden decoration and as a cut flowers. This paper evaluated the influence of the planting times and the size of the corms on the some characters of ornamental interest of Crocosmia plants, in the agroecological conditions from northeastern Romania (Iași). The corms of Crocosmia 'Lucifer' from two size categories (3-5.9 g and 6-9 g) were used, which were planted in the experimental field in November and April. The observations and determinations made during 2018-2021 highlighted the fact that from the corms with a mass between 6-8 g, planted in autumn, they ensured the obtaining of plants with the highest number of flower stems and the most flowers on the stem. Regarding the height of the flower stems, the best results were recorded in corms with a mass between 3-5.9 g, planted in autumn. In the case of corms planted in the spring, the results were less significant, except for the number of shoots in plants resulting from large corms (6-8 g). The flowering period was longer to the plants obtained from corms of 3-5.9 g, planted in autumn. [ABSTRACT FROM AUTHOR]

In any city we find spaces that, either because of unsustainable exploitation or because of the wrong approach, fail to reach their full potential. As a result, there is a need to pay particular attention to these types of sites for their introduction into the landscape circuit. Thus, the paper intends to come up with a solution that transforms a space without identity of 35,125 m2, with a great need for completion, innovation, within a reasonable limit, in a spacevolumetric environment that is more accessible to both the inhabitants of Orătie city, as well as for the municipal administration. The architecture of the present arrangement proposes a different architectural concept, in which the landscape elements that come into its composition define the mixed style. The scenario, is proposed to be constructed from regular shapes that combine with free forms and creates a harmonious, balanced rhythm and thus strengthens the feeling of spatiality. The interior path of the proposed green spaces within the layout, offers a gradual transition, between the different functional areas. By designing the rehabilitation solution within this project, we aspired to increase the value of the subconscious and the consciousness of the inhabitants of Orătie city, adopting a timely energetic attitude to heal a land of no value.

The aim of the researches was to establish the upper limit of CuCl2 concentration in soils that the Dianthus superbus L. and Globularia punctata Lapeyr. species could tolerate without significantly affecting the germination and the plant sprouting process. The experiment was conducted in 4 variants of 3 repetitions, each repetition including 50 seeds. In order to moisten the substrate, water was used for the control variant and for the other three variants, solutions of different CuCl2 concentrations were used. The necessary quantity of CuCl2 was calculated, in order to obtain certain concentrations in the substrate V2 - 0.1 mM; V3 - 1 mM and V4 - 10 mM. Testing seed germination under CuCl2-polluted conditions has led to the study of all species studied to obtain a percentage of germination that decreased with increasing concentration. The increase in CuCl2 concentrations in the germination substrate in Dianthus superbus induced a slight delay in the emergence and a shift in the number of days in which the rising occurred.

Studies conducted by researchers in our country points out that most of the installed protective forest cultures on degraded land have as basic species black pine (Pinus nigra) and sylvester pine (Pinus silvestris). It should be noted that under massive regeneration and introduction under the shelter of the massive, in gaps created by extracting damaged pine specimens, of some genetically valuable native species, are an effective forestry method of transition for temporary forest ecosystems to stable (areal) forest ecosystems, but also of increasing the stability and functional efficiency (of protection) of arboretum located in less favorable places (moderately eroded land and potentially sliding lands). Ecological forestry reconstruction actions that are mentioned in this paper are important for the recovery of the hydrological and antierosion protective capacity of these tree stands, but also for assuring their continuity on degraded lands, thus obtaining a more effective protection of the places next to forested areas.
