the main objective for plant breeding is to increase genetic diversity. mutation induction is a method to increase genetic diversity associated with selection, recombination, or a combination of these approaches in plant breeding. the present research was aimed to compare efficacy of different doses of gamma rays (150, 200, 250, 300 and 350 gy and zero dose control) on the sesame morphological ...

The aim of this research was to accurately measure the surface of the semi lunar articular surface of the pelvis (facies lunata acetabuli) and the variability of the acetabular geometry, as well as to determine the correlation between measured parameters. 30 macerated anatomical specimens of pelvic bones were measured. The radius and depth were measured in the classical way, while cartilaginous...

Chemical and morphological characterization of different parts of banana plant(Musa paradisica) (peduncle, leaf stalk and pseudo stem) were carried out in orderto assess their potentiality for chemical pulp. Each portion was tested forextractives, sodium hydroxide solubility, ash, lignin, cellulose and pentosancontents as well as their fiber length and width. These segmented parts werecharacter...

During last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. However, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. In this paper we examined dung germinating seed content, seed deposition p...

abstract in order to investigate the effects of different irrigation regimes on yield and yield components of three chickpea cultivars, an experiment was conducted during the 2007 growing season at mashhad. six irrigation regimes including i1= full irrigation, i2= irrigation at branching, i3= irrigation at flowering, i4= irrigation at pod formation, i5= irrigation at seed filling stage, and i6=...
