Although the aleurone layer of ceral grain seeds has many advantages for the study of gibberellin action, it has the disadvantage that the hand-isolation of the aleurone layers is time-consuming. To overcome this disadvantage, a commercially available pasta machine was modified and used to remove aleurone layers from imbibed barley (Hordeum vulgare) seeds. This equipment allows isolation of a t...

Dry seeds of seven winter wheat varieties and one line were exposed by gamma-rays and chemical mutagens to determine their effect on plant grows and development. Next parameters have been investigated – plant survival, pollen fertility, components of yield structure. Informative value by mutation depression evaluation of all parameters has been developed. The most informative parameters for mut...

To evaluate the effect of plant density and detopping on grain yield, protein content biological yield harvest index, growth indices, number of cob in each plant, No. of row per ear, No. of grain in each row, thousand seed weight of corn (Zea mays L. ar. SC 704), an experiment was conducted at the experimental statues of Research Center of Uremia Agricultural College in 2004. The Treatment desi...

In order to investigate the effect of planting method and sugarcane residue compost fertilizer on morphological and physiological traits and grain yield of corn, a field experiment using a split-plot arrangement was accomplished in a randomized complete block design with four replicates in Mian-Ab, Shooshtar, south-west Iran in summer 2018. Experimental factors included four planting methods (o...

In order to investigate some physiological responses and grain yield of five chickpea cultivars under different levels of moisture and salinity, two experiments (i.e. a pot and a field experiment) were conducted in 2012. In the pot experiment, effects of four salt levels (i.e. control, 50, 75 and 100 mM of NaCl) on five chickpea cultivars, i.e. Arman, Azad, Hashem, ILC-482 and Noorabad were stu...

The aim of this research was to assessment of drought tolerance in bitter vetch (Vicia ervilia L.) ecotypes. For this purpose, 16 ecotypes collected from four provinces (East Azerbaijan, West Azerbaijan, Ardabil and Zanjan) of Iran, were evaluated using randomized complete block design with four replications in three separate experiments (60, 90 and 120 mm water evaporation from A pan) during 2...
