sugar beet as an industrial crop plays a main role in satisfying domestic demand of sugar. study on the production efficiency of sugar beet is important because this is a factor that influences production without additional cost. in this study, data envelopment analysis approach (dea), was implemented to calculate technical, administrative and scale efficiency of sugar beet production. also opt...

Abstract Pectin from two different plant sources: apple and sugar beet was studied. Apple pectinwas modified by chemical treatments such as: acid, alkali and ammonia, so as to obtain an ester levelequal to or less than 50 %, which is described as low methoxyl (LM) pectin. LM pectin form gelswith significant characteristic. In this study, de-esterification of apple pectin with acid treatmentresu...

Both structural and functional properties of belowground plant organs are critical for the development and yield of plants but, compared to the shoot, much more difficult to observe due to soil opacity. Many processes concerning the belowground plant performance are not fully understood, in particular spatial and temporal dynamics and their interrelation with environmental factors. We used Magn...

This article focuses on the development of the method for the genetic classification of agamospermous reproduction types in plants using sugar beet as an example. The classification feasibility is ensured by the use of isozymes as genetic markers allowing the identification of all three phenotypic classes in the progeny of individual heterozygous diploid plant and is based on different phenotyp...

Beet necrotic yellow vein virus (BNYVV) is a member of the genus Benyvirus (21,22) and causes the disease known as rhizomania. It often is reported to be the most important sugar beet (Beta vulgaris L.) virus (17). BNYVV is transmitted by the plasmodiophorid, Polymyxa betae Keskin (1,2,6). In the United States, the virus first was identified in California in 1984 (5) but now occurs in every maj...

Extended Abstract Introduction and Objective: Sugar beet is one of the most important agricultural products in the world and most of the sugar consumed in our country is prepared from this plant. Plant breeding programs are based on creating variety and selection of quantitative and qualitative traits. Examining genetic diversity is the first step in breeding programs. Material and Methods: I...
