Stem reserves of barely can be an important contributor to grain filling particularly under condition is limited such as salinity stress. The aim of this research was to study dry matter accumulation and remobilization ability in different internodes of some Iranian Barley varieties and promising lines under salinity and normal conditions. The research was set up as two Randomized Complete Block design with three replications at the agriculture research station of Neishabur, Khorasan Razavi, during 2013-2014. The amount of dry matter accumulation and remobilization were determined using method. The relationship between length and specific weight of internodes with dry matter accumulation and Remobilization was investigated. The results showed that lower internodes had maximum dry weight and specific weight in both of experimental conditions. Maximum remobilization was obtained from penultimate and lower internodes in normal and salinity conditions, respectively. A positively significant correlation was observed between seed weight per spike and the amount of Remobilization from all of internodes in saline condition. Results indicated that dry matter accumulation and remobilization ability are two different mechanisms that inherent from parents to progeny. Also in this study it was found that new tolerant promising lines compared to old tolerant varieties, had internodes specific weight, dry matter accumulation and remobilization ability.
