CONSIDERATIONS REGARDING THE VASCULAR FLORA OF SOME FRUIT ORCHARDS IN DOLJ COUNTY, ROMANIA

2023-12-14T09:28:56+00:00

Through the environmental requirement imposed by inter-rows, the eco-scheme contributes to the CAP objective of biodiversity conservation, as well as increasing the soil's carbon sequestration capacity and improving the quality of the soil structure, the main natural resource in agricultural activity. The present work aimed to analyze the vascular flora from some fruit orchards in Dolj County, Romania following a taxonomic study, starting from the need to establish a vegetal soil cover with spontaneous plants, both specific to the region and environmentally friendly. Following the observations made, it was found that the floristic composition of the grassy cover in the orchards in Dolj County is variable depending on the age of the orchard and the works that were carried out between and on the rows of trees. In orchards where human intervention is low, there is a good representation of taxa belonging to the Fabaceae family (eg Trifolium repens, T. pratense, Medicago arabica, M. sativa). On the other hand, isolated species are present in well-maintained orchards, especially from the category of weeds that can be difficult to fight (e.g. Sorghum halepense, Xanthium italicum, Conyza canadensis, etc.). Observations will be continued to consider the effect of wild plants on the environment and to establish an area-specific varietal soil cover for keeping the row spaces grass-covered.

POSSIBILITIES OF USING EVERGREEN SPECIES IN EXTERIOR DECOR

2023-12-18T09:37:24+00:00

In our country's conditions, most herbaceous and deciduous ornamental plants lose their ornamental qualities during the cold season, and the landscape becomes dreary. In these circumstances, the group of evergreen ornamental plants, also known as evergreens, provides color and texture in landscaping due to their leaves that remain green throughout the year. Although the concept of an "evergreen" garden often brings conifers to mind, in landscape design, the association of species belonging to a single plant group is avoided due to visual monotony. Therefore, in this type of permanently green garden, and not only, the combination of conifers with other groups of species with persistent foliage (deciduous trees and shrubs, evergreen herbaceous perennials, succulents) is essential. Based on these considerations, our work aims to create landscaping solutions that include this variety.

2023-12-18T08:45:35+00:00

A common species here too is Linaria vulgaris Mill. The plant grows in small, dense clumps around and within various agricultural soils. Recently, there has been an increase in the spread of this weed, especially in the area of poor soils in the south of the territory. Morphological characters have shown a continuous evolution, depending on the existing ecotype at a given time. Thus, the raceme measured 13 cm long and weighed approx. 240 mg. 7.2 seed capsules formed on one raceme. The capsules had a length of 8 cm, a width of 4.7 cm and a mass of 115 mg. 90 seeds were formed on one raceme, the average diameter of which was 2 mm. Significant positive correlations were obtained between most determined characters. Negative correlations were only between seed fin width with the other characters. The determinations made demonstrated the increased adaptability of the weed to the current ecological conditions of the albic luvic soil from South part of country.

RESISTANCE OF THE NEPTUNE APRICOT VARIETY TO LATE FROSTS

2023-12-18T11:27:42+00:00

The Dobrogea region is a favorable area for apricot culture, this species ensuring relatively uniform production over the years. However, the temperature variations in the long and cold springs influence the production of certain apricot varieties in operation. The Neptun apricot variety studied in recent years showed and proved a uniformity in the given productions even though the late frosts were more and more frequent. Low temperatures affect apricot plantations, causing irregularities in the regularity of fruit production and their quality, gummy leaks and awareness of trees to the attack of apricot-specific pathogens. The research was conducted in a orchard of apricot aged 9 years, located at 18 km away from Constanta. Trees planted at a distance of 4x4m were studied during the vegetation season paying particular attention to resistance to low temperature. In the winter of 2019, temperatures in winter decreased to -14 degree C and produced losses of flower buds. In the spring of 2020, the ‘Neptun’ variety bloomed well, 80% of flower buds being resistant to negative temperatures from winter. In 2021 was a warm winter but the temperature decreased in January to -14 degree C and the trees suffered a thermal shock. Following, resistance to frost decreased and the percentage of flower buds affected was 84,8%. In 2022 ‘Neptun’ variety was not affected. In February of 2023 were, recorded temperatures of -10 degrees C associated with very cold wind, the flower buds were affected in 80,6%.
