Therefore, different kinds of studies should be followed as metabolic interactions, physiological reactions and biochemical profile which may lead to the real understanding of fungicide mechanisms.

RESEARCH REGARDING THE VARIETY IN OBTAINING HIGHER QUALITY WHEAT PRODUCTION, ON SANDY SOILS IN SOUTHERN OLTENIA, IN THE CONTEXT OF CLIMATE CHANGE Mihaela CROITORU, Iulian DRGHICI, Reta DRGHICI, Milica DIMA Research-Development Center for Plant on Sands Soils Dbuleni, 130, Victoria street, 207220, Dolj, Romania Abstract Scientific Papers. Series A. Agronomy, Vol. LVI, 2013 ISSN 2285-5785; ISSN CD-ROM 2285-5793; ISSN Online 2285-5807; ISSN-L 2285-5785 Corresponding author email: mhlcroitoru@yahoo.com Wheat has a great importance as a food product, providing a large portion of carbohydrates and proteins necessary for man and more than half the calories consumed by humans. Given the economic importance and special role it holds in human nutrition, basic trend now and in the future is to increase global production. In addition to this direction is emerging ever stronger and other trends, such as the introduction in production of varieties with a high content of protein with increased nutritional value and superior cultivation with baking qualities. Climate change last period of time with pronounced drought and even climate aridisation trend in southern Romania, led to increased frequency of drought years. At CCDCPN Dabuleni in 2010-2012 were studied in terms of quality of grain, several varieties of winter wheat. Productivity and product quality are strongly influenced by abiotic limiting conditions (thermic and hydric stress) exhibited during the experiment. The best production results were obtained in the climatic conditions of 2010, the varieties: Albota 69 (4133 kg/ha), Delabrad (4267 kg/ha), Glosa (4233 kg/ha) and Ciprian (4356 kg/ha) the production increases achieved statistically very significant. Negative and significant correlation between wheat production and the number of days to gray, in conditions of droughty year, shows that precocity variety can be a measure that can contribute to mitigate effect drought and heat. Protein content and wet gluten resulted in wheat grains gives a good quality of production: Delabrad (15.2% protein, 33.2% wet gluten), Boema (14.8% protein, 33.8% wet gluten), Glosa (14.9% protein, 31.4% wet gluten), etc.. Key words: climate change, quality, variety, wheat. INTRODUCTION Wheat is the most important cultivated plants, with great food weight. Having regard to the economic importance and special role it holds in human nutrition, the basic trend of now and in the future is of increasing global production. In addition to this direction is emerging increasingly stronger and other trends, such as the introduction in production of varieties with a high content of protein with enhanced nutritional value and superior cultivation of varieties with of bakery qualities. Climate change in last period of time, with pronounced drought and even climate aridisation trend in southern Romania have led to increased frequency of drought years. Variety represents an essential factor in the wheat culture technology in order to obtain constant and superior production quality, and this fact is even more evident during drought conditions. 212 Choosing varieties resistant to thermic and hydric stress conditions (drought, drought accompanied by heat) plays an important role in the fight against this phenomenon, in recent years more and more. Numerous studies highlights the differences between variety on the response to water shortage, as well as the difficulty of the merge a high production potential and features higher quality with good tolerance to drought (Blum, 1996; Mustatea et al., 2003; Olteanu and Tabara, 2008; Andronache, 2009; Idikut et al., 2009; Pasha et al., 2009; Voichita et al., 2010; Hrušková et al., 2012). The present paper aims at behaviour some varieties of winter wheat in during 2010-2012 under the aspect of adaptability to climatic conditions, specific to areas of sandy soils of southern Oltenia manifested in the period the production test capacity and quality.
