SCDVV Blaj Summary

 

Research Station of Viticulture and Enology Blaj was founded in year 1946, in the village of Crăciunelui de Jos whilst the viticulture studies started here  have represented the bases for the development of viticulture in Transylvania. In the meantime, researches have been started as concerns selection, amelioration and production of the planting material.

 

In 1950, agro-technical and vinification researches have been initiated and starting with the beginning of year 1953, the scientific thematic has included aspects of agro-chemistry and phyto-sanitary protection, as well. 

 

In 1960, due to the increase of the patrimony and diversity of research thematic the headquarters of the station has been transferred to Blaj. Collaboration conditions have been created for the enlargement of the activity with other viticulture units from the area, with respect of the production supervising and monitoring, under direct assistance of the researchers from SCPV Blaj. 

 

The development of viticulture in Transylvania has required knowledge and the establishment of  systems for vine from this specific area. Pedo-climatic conditions have encouraged the cultivation of vine for the production of white wines.

 

At the time being, the station develops its activity in the following directions:

 

Scientific research  in the fields of: viticulture, vinification and floriculture, directly  referring to  genetics and improvement of viticulture varieties, production of planting material with high biological value, agro-techniques and viticulture ecology , agro-chemistry, physiology and biochemistry, protection of plants, land survey, vinification, wine chemistry and microbiology.

 

The activity of research development and assessment is based mainly on the cultivation of vine and production of high quality white wines for inner and international market. 

 

The station also produces: viticulture planting material from clones and varieties newly created in its own research sector, horticulture planting material, fruits, vegetables, flowers and vegetable and flower seeds. 

 

3.  Technical assistance granted to the influence zone of SCPV Blaj by  specialists in viticulture and vinification:. 

 

Extension and generalisation in the production of research results applied in the influence zones of the station ( Alba, Cluj, Bistrita Nasaud, Hunedoara, Mures, Salaj and Sibiu counties) by setting up of new vine plantations with superior biologic materials, by extension of new varieties, which were recently patented and of clones obtained at the Research Sector, by participating to the elaboration and checking of the setting up of projects as concerns new plantations and technical guiding for maintenance and exploitation of the existing plantation, organisation of meetings and practical demonstrations or visits to the experimental lots ;

Integration of Research into Instruction:

 

Nearby SCPV Blaj, is functioning “ the College of Viticulture and Wine Technology” 

(duration of studies:3 years), section of the Faculty of Horticulture in the framework of  USAMV Cluj-Napoca (University of Agricultural Sciences and Veterinarian Medicine of Cluj-Napoca).
