Study the Response of Cucumber Plant to Different Magnetic Fields
Keywords:Magnetic field, Cucumber, Direct magnetic current, Alternative magnetic current
Magnetic fields (MF) are widely distributed in the environment and their effects are increasing due to various instruments that are used in industry and medicine. In the present experiment, the growth and productivity of cucumber plants of seeds in which affected by different magnetic fields was investigated. The soaked seed samples of cucumber were exposed to a 20?T AC magnetic field for 30 minutes. Similar seed samples also were treated with DC magnetic fields of 5?T for 30 min. To compare the effect of different magnetic fields, control samples with three replications were placed in gape out of magnetic field for 30 min. Results of study showed that the germination of seeds was significantly influenced by different magnetic fields depending on the days after treatment application. The first germinated seeds were observed two days after beginning of test in DC magnetic field (0.7 seed) treatment. In the last days of experiments (day ninth), no difference was observed among treatments. The growth behavior of seedling of cucumber affected by different magnetic field in comparison with control plants in greenhouse showed that seeds in which treated with AC magnetic field have better growth rate. The results of evaluation of plants in the field showed that parameters like fruit length (FL), the diameter of fruit (FMD), Fruit weight (FW), number of side stem (NSS), flower number (NF) and the number of flower per main stem were not significantly different at different times of experiment. Contrary to that, parameters such as the number of fruits per plant (NF) and the length of main stem (LMS) were significantly increased by time. Based on the obtained results of the germination, greenhouse and field trials it can be concluded that direct magnetic field stimulates seed germination and increases the growth rate and vigor of seedling especially at the beginning of germination. Generally, it can be indicated that the initial effect of magnetic field on the germination rate and the growth of seedling is very positive since it induces an improved capacity for nutrient and water uptake, providing greater physical support to the developing shoot.
