Yield is a function of root distribution and activity. In flood conditions, root growth and efficiency are essential for crop productivity. The goal of this study was to investigate the effect of different irrigation regimes on the root development, yield and yield components of green pepper (green Hashemi cultivars). This study, which was based on a completely randomized design with three repl...

Knowledge on physical and mechanical properties of fruits is necessary for designing and optimizing processing systems. In this study, several physical and mechanical properties of date fruit (Kabkab cultivar) and its seed were determined. The average of length, width, thickness, unit mass, 1000 fruit mass, geometric mean diameter, unit volume, surface and projected areas, sphericity, fruit tru...

In order to evaluate the effect of different training systems on growth, yield and fruit quality of greenhouse cucumber (Cucumis sativus cv. Gohar) this experiment was set out in a randomized complete block design with three replications. Treatments consisted of four training systems including twin-stem system (V-shape), modified twin-system, high-wire system and horizontal system (single-stem)...

DOR: 98.1000/2383-1251.1397.5.71.9.1.1575.1605 Extended abstract Introduction: Generally speaking, plants contain various organic compounds which could influence the behavior of plant communities. These compounds are basically secondary metabolites which are found in various parts of plants such as rhizomes, roots, stems, leaves, flowers, fruits and seeds. The objective of the present st...

Abstract In order to study the effects of different levels of nitrogen (N) and molybdenum (Mo) in nutrient solution on quantitative and qualitative traits and nitrate concentration of cucumber (Sultan cv.), a factorial hydroponic-experiment with completely randomized design and three replications was conducted in the greenhouse of Soil Science Department, Zanjan University, in 2009. The concen...

in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
