Study the amount of dry matter remobilization from different aerial organs to grain on barley varieties under rain-fed condition

In order to study dry matter remobilization on barely, an experiment was carried out in Agriculture and Natural Resources Research Station of Ardabil in 2011-2012. The experiment was conducted as randomized complete blocks design with three replications. Five barley varieties as Aday, Tokak, Orza-96, Sahand and Abidar were evaluated in terms of the amount of dry matterremobilization from different aerial organs. The results of variance analysis showed that there was significant different between barley varieties in term of DM remobilization of stem, spike, leaves (expect flag leaf), peduncle and total above ground organs (α= 1%). In between barley varieties, Orza-96 had the highest DM remobilization from stem, spike, leaves, peduncle and total organs however in term of DM remobilization of stem and spike it wasn’t significantly different with Tokak and Aday, respectively. Sahand and Abidar varieties had the lowest total DM remobilization
