In order to study the effects of different levels of nitrogen fertilizer and plant density on grain yield and its components in sunflower, an experiment was conducted using 'Record' cultivar at the Research Farm of College of Agriculture, Isfahan University of Technology in 1996. Four levels of nitrogen (0, 75, 150 and 225 kg/ha) and four plant densities (65000, 75000, 85000 and 95000 plants/ha...

tuberose (polianthes tuberosa l.) is one of the most important cut flowers in tropical and subtropical areas. this flower has forth order in cut flower and second order in bulbous plants production in iran. plant spacing and nitrogen necessity are the most important factors for tuberose quality and quantity. in this study, field experiment carried out as factorial design in randomized complete ...

This research was carried out to evaluate the effect of two mycorrhiza species on growth, yield and oil content of geranium under salinity stress. The experiment was done at research greenhouse of Faculty of Agriculture, Lorestan University, Iran, in 2014. Four levels of substrate (sterilised and non-sterilised control soil and sterilised soil inoculated with Glomus mosseae or G. intraradices),...

The developmental variation in stem height with respect to stem diameter is related to a broad range of ecological and evolutionary phenomena in trees, but the underlying genetic basis of this variation remains elusive. We implement a dynamic statistical model, functional mapping, to formulate a general procedure for the computational identification of quantitative trait loci (QTLs) that contro...

Due to their theoretical advantages, hip systems combining modular necks and large diameter femoral heads have gradually gained popularity. However, among others, concerns regarding changes in the load transfer patterns were raised. Recent stress analyses have indeed shown that the use of modular necks and big femoral heads causes significant changes in the strain distribution along the femur. ...
