Abstract:

In order to investigate the effect of osmotic stress on germination indicators of eight genotypes of sugar beet, afactorial experiment was done in a randomized complete block design on 2011 with three replications. In this study indicators Coefficient of velocity of germination, Germination rate index, Final germination percentage, Mean germination time, Germination speed and Mean daily germination were evaluated. The results showed that the drought conditions all traits had significant difference at 1% probability level. According to result, therewere significant difference between all evaluated genotypes except Mean daily at 1% and 5 probability levels. Interaction of Drought stress × genotype was insignificant for all traits. Genotype 3 with an average of 9.67 percent had the highest percentage of germination, and genotype 1 with a mean of 78.66 percent had the lowestpercentage of germination. Drought stress reduced the 10.99 % GI, 4.62% CVG, 47.85% MDG and 6.66% GS, and was increased the 4.61% FGP and 4.97 % MGT.
