Abstract:
The use of nanotechnology can fulfill food problems through crop improvement in future time. Nanoparticles can enhance the morphological growth and fruit yield of plants. Titanium is considered beneficial for the growth rate of plants. Titanium dioxide (TiO2) nanoparticles were synthesized by precipitation method. The nanoparticles were carried out at room temperature using TiO2, NaOH and HCl as precursors. Its characterizations were completed by PSA (Particle Size Analyzer), UV-Vis Spectroscopy, XRD (X-Ray Diffraction) recorded result was ranging from 60 to 200 nanometers and crystalline nature and SEM (Scanning Electron Microscopy) of TiO2 nanoparticles. In this research study, we treated Phaseolus vulgaris seeds with five different type 15, 30, 60, 120 and 240 mg l-1 TiO2 nanoparticles concentrations for 1 week (7 days) in the culture tubes and examined morphological such as germination rate and time of seeds, root and shoot growth, height, number of leaves, pods and seeds and biochemical changes. Low concentrations 30 and 60 mg l-1 boost root and shoot growth rate of seedlings and mature plants parameters. The high concentration 240 mg l-1 affected these parameters in a negative manner. At the low concentrations increased height of plants, number of leaves and changed structure and chlorophyll content and weight of seed in treated plants.
