THERMAL REGIME DURING COLD ACCLIMATION AND DORMANT SEASON OF GRAPEVINES IN CONTEXT OF CLIMATE CHANGES- HILLS OF CRAIOVA VINEYARD (ROMANIA)

The thermal regime during the autumn-winter seasons plays a decisive role in cold acclimation and survival grapevine in cold climates. This study aims at assessing the time variability of the thermal regime during dormant season, between 1961-2021, in the Hills of Craiova vineyard and its potential implications on the grapevine, especially regarding its acclimation to cold and its vulnerability to frost. The following observations and analytical data were used in order to assess parameters and indicators with negative thermal stress potential: minimum and maximum temperature (daily, monthly averages), absolute maximum and minimum monthly temperatures, the duration of frost (days), the frequency of several low-temperature thresholds and the temperatures preceding frost episodes.  

THE CURRENT STATE OF THE VITIVINICULTURE SECTOR IN ROMANIA

After Romania accessed the European Union in 2007 and especially after 2009, there were major changes in Romania in the viticulture and winemaking field regarding the alignment of the legal framework to the Common Agricultural Policy (P.A.C.). During the post-accession, there were both important quality leaps in this field and a series of difficulties imposing a synthetic analysis in order to identify certain solutions to diversify the vineyard range and to improve the quality of the winemaking products.In this framework, concerning the strategies and policies implemented in the vitiviniculture sector in Romania during the last decade, this study refers to the following aspects: assessing the reconversion-restructuring stage of the vineyards in Romania, assessing the stage of implementing national strategies to produce high-quality wine (with PDO and PGI), as important premises for providing quality and specificity to the wine products

EVALUATION OF SOME STRAWBERRY VARIETIES IN THE SOUTHERN AREA OF THE COUNTRY

The variety is supplemented annually with new foreign or indigenous varieties, so it is necessary to study the varieties in a region for the observation of the qualities, the defects and the restraint for the respective area only of those of quality, productive and very adaptable to the conditions in the area . Of the eight varieties studied, the earliest proved to be the Vibrant variety -12 days, followed by the Premial variety - 13 days, referring to the precocity index. In the first year of fructification, we mention that none of the eight varieties of strawberry has been affected by mildew. In the first year of fructification, the strawberries obtained in the eight varieties presented fruits of over 20.0 g / fruit. The following varieties of strawberry distinguish for their special colour: Vibrant, Premial, Elegance, Pegasus, Florence. In terms of fruit quality, most varieties have accumulated a score of over 30 points, which qualifies them as category I varieties

INFLUENCE OF ROOTSTOCK ON THE GROWTH AND FRUCTIFICATION OF PEAR VARIETIES IN OLTENIA

Pear extension is a necessity for our country. There are many areas favourable for the pear species in the country, and the Oltenia area has proved to be an area with particularly favourable climatic conditions for varieties and rootstocks. Depth of rooting, as well as branching, is a genetic feature of the variety and species. Within the experience, there are varieties with a highly developed radicular system (absorbent roots helping to absorb the fertilizer better) and such varieties with roots that reach 80 cm are Untoasă Giffard, Untoasă Hardy, Abatele Fetel and Cure. The period of growth of pear varieties ranged from 56 to 67 days. The varieties showed a good affinity of the two partners, namely a growing behaviour and very good development of the partners. Physical and chemical properties help us to orient the respective varieties for fresh direct consumption as well as for industrial processing in different forms. From the researched type there can be kept in the culture for the southern area of Oltenia the varieties: Untoasă Hardy, Passe Crassane, Olivier de Serres and Cure

Experimental beta beta'-iminodipropionitrile (IDPN) neuropathy: neurofilament profile of sensory, motor and autonomic nerves as seen by immunocytochemistry on whole-mount preparations

IDPN-induced changes in a variety of sensory, motor and autonomic nerves were studied by whole-mount immunocytochemistry. A full range of proximo-distal accumulations of neurofilament-like material was found, from paranuclear round bodies in perikarya to distal and preterminal axonal dilations. Conversely, both terminal areas and nodal-paranodal regions of myelinated axons showed striking, sharply localized loss of neurofilament-immunostaining. The latter change, when transport of neurofilaments is halted by IDPN, may indicate their local processing and/or differential transport at nodal-paranodal regions
