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...

Three maize hybrids (Baber, Pioneer 30P45 and Syngenta 6621) were compared for yield and yield components and correlations were worked out among the yield parameters at various nitrogen levels in an experiment conducted at Agricultural University, Peshawar, Pakistan during summer 2009. The experiment was laid out in randomized complete blocks with split plot arrangement having three replication...

to determine the optimum weed management method and plant population density on chickpea yield, a split plot experiment based on rcbd with four replications was carried out at the university of tehran research farm (located in karaj) during 2010-2011. the main factor consisted of nine treatments including: 1. trifluralin pre-plant, 2. pendimethalin pre-plant, 3. complete weeding, 4. imazethapyr...

The paper presents the results of two and three years research on effectiveness organic mineral complex fertilizers their combination with protectants for pre-sowing treatment seeds vegetative plants new varieties lentils, chickpeas soybeans. It is established that use above-mentioned agrochemicals as foliar top dressing promising agroeconomically justified. Grain harvest increases depending cr...

abstract: evaluation of drought tolerance for 20 barley genotypes were conducted under normal irrigation and terminal stress condition by withholding irrigation at the time of 50% flowering. drought effect on grain yield and plant total mass traits was studied and eight of stress indices including stress tolerance index (sti), stress tolerance (tol), stress susceptibility index (ssi), mean prod...
