Aeroponics is a modern and soilless technology that used for the efficient production of pre-basic seed potatoes, namely minitubers. This study aimed to evaluate effects cultivar type planting material on minitubers in aeroponic facility Guča, Serbia, at short, 7-day harvest intervals. Although cultivation prolonged vegetative cycle all five investigated cultivars, dynamics minituber formation ...
due to lack of knowledge management system in the organization of technical and vocational university of iran (tvuni) and losing good employees because of retirement and substitution causes huge amount of costs to replace the similar expertise. there is no any suitable system in the tvuni to store, to document, and to distribute knowledge. based on the university’s features such as it has diffe...
light is one of the important environmental factors seriously affecting plant growth. given the availability of roots in aeroponic system, the influence of various light rays emitted towards the root zone of anthurium was studied. foliar spray of calcium nitrate in concentration of 10 mm was tried because of the high importance of calcium element in enhancement of vase life and strength of cut ...
abstract abstract of thesis (includes summary, goals, execution methods, and results) story “al-obnosat al-bayza” is one of the short stories from “hanna mineh” collection. this story is a selection of lives of some humans during a voyage together, each of them is a symbol of human nature (love, mind, kindness) and examine social, cultural, and political aspects of governing system, and it...
in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
ABSTRACT Potato seed is one of the largest costs a crop. This mostly due to incidence and spread viruses that occurs when crop grown in open field. Thus, it necessary obtain virus-free potato plantlets through meristem isolation, with subsequent cultivation protected environment, where easier control virus-spreading insects. One way increase greenhouse viability by multiplicating using high tec...
The aeroponic production of certified seed potatoes is a booming alternative for arid and semi-arid areas where fresh water scarce soil-borne diseases nematodes preclude field production. Although widely used in aeroponics, nutrient-solution salinity effects have not been evaluated potatoes. This study aimed to (1) establish the best two nutrient solutions (Otazú vs. modified Furlani) at 20, 50...
The atomized nutrient solution droplet sizes and spraying intervals can impact the chemical properties of solution, biomass yield, root-to-shoot ratio uptake aeroponically cultivated plants. In this study, four different nozzles having N1 = 11.24, N2 26.35, N3 17.38 N4 4.89 µm were selected misted at three 30, 45 60 min, with a 5 min time. measured parameters power hydrogen (pH) electrical cond...
در این پروژه هدف طراحی و ساخت fluorescence detection systemجهت آشکارسازی مولکول های dna می باشد. در روش pcr، طی چندین چرخه دمایی، مولکول های dna کپی می شوند و سپس با استفاده از روش fluorescence detection، مولکول های بر انگیخته شده dna آشکارسازی می شوند. پس از آشکارسازی می توان به کپی و یا عدم کپی dnaها پی برد.می توان برای جداسازی مولکول های dna بر اساس طولشان، از روش gel electrophoresis استفاده...
