Aim and Background. In order to study the effect of drought stress on some quantity and quality characteristics of sugar beet genotypes a field experiment was carried out at Agricultural Research Station of Khoy in 2009. Materials and Methods. Treatments was arranged in strip block experiments based on completely randomized block design with three replications. Three sugar beet hybrid varieties were as Rasoul, Shirin and 7112.
Results. The results showed that the
water stress on root yield, white
sugar content, sugar content, root length, fresh and dry
weight of leaves, petioles and roots
were significant. Effects of cultivar on most
traits studied were significant, and Rasoul was
significantly higher than others of
root yield and white sugar
yield.
The interaction between cultivar and water
stress was not significant. Due to stress
and free- stress environments, Shoot fresh weight reduction showed
the water storage in cultivars is
non-equal. Decrease in shoot dry
weight and total dry weight
indicate that drought stress have
reducing affects on the growth
of shoot parts and total
dry weight.
Conclusion. Noticeable point in the results was that the traits sugar content and white sugar yield, impurities of nitrogen, sodium and potassium, and molasses sugar in two environments revealed no significant difference.
