Abstract:

To evaluate storage and Remobilization ability photosynthetic material in 10 variant of wheat and bread, a pilot randomized complete block design was done under optimal conditions and with drought stress at the end of 2012 in the field of Islamic Azad University, Ardabil branch. Characteristics of the amount of Remobilization of material and storage from stem to grain, contribution amount of stem reserves to the grain yield, transfer efficiency of carbohydrates from stem to seed and special weight of stem were measured at physiological maturity. The results of combined variance analysis showed that the effect of the environment (drought), genotypes and interactive effect of genotype on all of the traits showed significant differences at 0.1 levels that implies to the large impact of environment on these characteristics. Results showed that Remobilization amount of stem reserves in stressed environment is significantly more than its favorable environment. Only two types of 10 types had greater efficiency in the transference of carbohydrates in stressed condition. So we can conclude that Remobilization of material in optimal moisture condition plays important role in the grain yield. Contribution amount of stem reserves in stressed condition was variant from %7.3 in cultivar type to %28.75 by Trakya type. In terms of transfer efficiency of carbohydrates Azar-2 figure easy the lowest.
