In order to evaluate grain yield potential and study dry matter remobilization to seed, 8 commercial bread wheat cultivars were examined in two separate experiments, using randomized complete block design with 4 replications in 2003. There were significant differences for most traits in normal and drought conditions. Sarday variety had the least grain yield in the two environments. There was c...

Abstract Five bread wheat (Triticum aestivum L.) cultivars including Kavir, Pishtaz, Niknejad, Omid and Roshan were evaluated in a split plot experiment based on randomized complete block design with three replications. Water stress and well-watered conditions were assigned to the main plots and varieties to the subplots. Water stress was imposed by withholding irrigation at the booting stage....

kochia is a halophyte plant and is a good source of forage for livestock under saline irrigation. in order to investigate the salinity effect on morphological and forage characteristics of kochia, an experiment was conducted. three saline waters (5.2, 10.5 and 23.1 ds m-1) and three kochia ecotypes (birjand, borujerd and sabzevar) were allocated as main and sub plots, respectively, in a split p...

Mutant genetic materials are valuable tools for understanding the physiology of remobilization and could be useful in the breeding of drought tolerant varieties. Two advanced mutant lines of bread wheat (T-67-60 and T-65-7-1) along with their wild type (Tabasi Cv.) were planted at two moisture conditions (normal and 30-40% of field capacity) as a factorial experiment in format of completely ran...

Understanding the nitrogen remobilization by plant, in order to obtain cultivars with higher quality, has specific importance in plant physiology. In this experiment, a bread and a durum wheat cultivar, were treated with different rates and times of nitrogen application, by using split factorial on the basis of randomized complete block design with three replications at Shiraz region during 200...

wheat stem reserves can be an important contributor to grain filling particularly under drought conditions. knowledge concerning genetic variation in stem reserve could be empolyed to develop wheat genotypes more adapted to harsh environments. the aim of this research was to study the ability to store assimilates in stem and their re-mobilization to the grain in all the 81 iranian wheat cultiva...
