Abstract:

To study the physiological aspects of drought on a number of traits of 20 sugar beet genotypes, an experiment was performed in 2014 in the laboratory of Islamic Azad University, Ardebil branch as two-factor factorial in a completely randomized block design with three replications. The first factor included zero control (water) and 0.8 MPa, while the second factor included studied genotypes. The examined traits included plant height, leaf length, leaf width, number of leaves per plant, root length, fresh weight of shoot and root fresh weight. Analysis of variance results showed significant differences between stress levels except for root length and root fresh weight in the rest of traits. Also, there were significant differences between studied genotypes regarding all the traits. Also, the only interaction of stress levels × shoot fresh weight genotype showed a significant difference. Also, a reduction was seen in plant height, leaf length, leaf width, number of leaves per plant and root fresh weight in stress conditions compared to normal terms, respectively as 29.28%, 26.95%, 32.92%, 7.77% and 37.14%.
