The aim of the present study was investigating some ecological factors in the habitats of four species and determining the most significant variables affecting the presence and distribution of these species. Study area, which was about 4600 ha, was located at Polur, Mazandaran province. For this purpose, after primary survey and selection of main plant species, 3 transects 150 meter in length w...

In order to study inheritance of traits (Height, Peduncle length, Extrusion peduncle length, Diameter first internode, Diameter secondary internode, Diameter third internode length of secondary internode, length of third internode) associated with height in bread wheat, seven cultivars of bread wheat with their F1 progenies produced through a half diallel mating design were planted in a randomi...

     In present study, 72 barley double haploid lines with two parents were studied. The experiment was arranged in a completely randomized block design with two replicates under normal and boron stress in hydroponic condition in 2013.The traits Fresh and dry weight of root and shoot, length of root and shoot, length of the largest leaf and the height of whole plant were measured. Statistical a...
