Title: CORRELATION OF MORPHOLOGICAL AND PHYSIOLOGICAL SUGAR BEETTRAITS WITH ETHANOL PRODUCTION FROM FRESH ROOT AND MOLASSES
Abstract: Environmental pollution as a basic challenge of man at this century along with pollution increasing followed by high oil products changes to serious problem. Nowadays ethanol as a clean energy source and reliable have been focused by scientists. Studying the relation of ethanol production with some morphological and physiological traits in sugar beet varieties, experiment was conducted with 10 varieties in complete block design with 3 replications at Khoy - Iran agricultural research station in 2009. Bio-ethanol was produced by Saccharomyces cerevsiae fermentation from root and molasses of sugar beet varieties. The results showed significant positive correlation between root, raw sugar and white sugar yields with ethanol production from sugar beet roots. Molasses sugar also showed high positive correlation. But ethanol production from molasses, the highest correlation belongs to potassium and sodium impurities of root. There was significant high negative correlation between molasses ethanol yield with raw extract purity. The IR2 variety with 9285 lit/ha was superior in root ethanol production and highest production of molasses ethanol observed with fodder beet variety of 7112 with 804.3 lit/ha. It seems commercial traits of sugar beet is suitable for sugar production and so for bio-ethanol production.
