The morphophysiological response of Phaseolus vulgaris L. to low-power electromagnetic radiation was investigated in order to assess the potential harmful effects of long-term continuous exposure. The plants were grown in two separate electromagnetic field (EMF) shielded rooms, in a controlled, greenhouse-like environment. One batch was continuously irradiated during the growth period (from sowing to maturity) and the other one was used as a reference. An unmodulated signal at 915 MHz (the central frequency between the uplink and downlink of the GSM900 mobile communications band) was used, with a maximum power density of 10 mW/m2 measured near the plants. The plants were analyzed using ultraviolet-visible, statistical, morphometric, and electron microscopy methods. Significant differences were observed regarding the height of the plants, number of inflorescences, and chlorophyll and carotenoid content, all closely connected with the ultrastructural changes observed in the leaves. The irradiated batch grew higher (19% increase in plant height, 20% increase in stem and leaves' dry mass), with 18% fewer inflorescences, and extremely long roots (34% increase in dry mass). The ultrastructure of the irradiated leaves showed irregular cells and a higher content of plastoglobules in the chloroplasts. All results indicate that the irradiated plants suffered significant morphological modifications during their long-term exposure to the specific EM radiation.

长期暴露于低功率915 MHz未调制辐射对菜豆的影响。

研究菜豆对低功率电磁辐射的形态生理响应，以评估长期连续暴露的潜在有害影响。这些植物在受控的温室状环境中，在两个独立的电磁场（EMF）屏蔽室中生长。在生长期间（从播种到成熟）连续照射一批，另一批用作参考。使用了915 MHz（GSM900移动通信频段的上行链路和下行链路之间的中心频率）的未调制信号，在工厂附近测得的最大功率密度为10 mW / m2。使用紫外可见，统计，形态学和电子显微镜方法对植物进行分析。观察到植物的高度存在显着差异，花序数，叶绿素和类胡萝卜素含量均与叶片中观察到的超微结构变化密切相关。受辐照的批次生长更高（株高增加19％，茎和叶的干重增加20％），花序减少18％，根长极长（干重增加34％）。辐照叶片的超微结构显示出不规则的细胞，叶绿体中的质体球含量更高。所有结果表明，受辐照植物在长期暴露于特定EM辐射期间会发生明显的形态学改变。生物电磁学。©2020生物电磁学会。受辐照的批次生长更高（株高增加19％，茎和叶的干重增加20％），花序减少18％，根长极长（干重增加34％）。辐照叶片的超微结构显示出不规则的细胞，叶绿体中的质体球含量更高。所有结果表明，受辐照植物在长期暴露于特定EM辐射期间会发生明显的形态学改变。生物电磁学。©2020生物电磁学会。受辐照的批次生长更高（株高增加19％，茎和叶的干重增加20％），花序减少18％，根长极长（干重增加34％）。辐照叶的超微结构显示出不规则的细胞和叶绿体中更高的质体球含量。所有结果表明，受辐照植物在长期暴露于特定EM辐射期间会发生明显的形态学改变。生物电磁学。©2020生物电磁学会。所有结果表明，受辐照植物在长期暴露于特定EM辐射期间会发生明显的形态学改变。生物电磁学。©2020生物电磁学会。所有结果表明，受辐照植物在长期暴露于特定EM辐射期间会发生明显的形态学改变。生物电磁学。©2020生物电磁学会。
