Abstract :
In order to the effects of deterioration, accelerated aging and planting density on yield, yield components and seed characteristics of produced wheat seeds in Gonbad region, an experiment was conducted as factorial arrangements, based on completely block design with three replication at researcher station in 2017. Treatments were combination of three factors, i. E. leaf deterioration (without leaf deterioration, removing all leaves, removing all leaves except flag and Removal of all leaves except flag leaf and the leaf below), accelerated aging (without deterioration and deterioration for 72 hours at 45 centigrade in incubator) and plant density (350, 400 and 450 plants per square meter). The simple effected of removing leaves and accelerated aging and plant density were significant on yield and its components at 0.01 probability level. The yield and its components decreased with increased removal of the leaves, such the grain yield with leaves removal decreased from 4125 to 3670 kg/ha. There was significant deterioration among accelerated aging for studied traits. The seed yield was 3423 and 4244 kg/ha for accelerated and non accelerated treatments.
