Nourishment plants during the field time is a must; to have healthy, high productive and self-propagating plants. The trendy nano-fertilizers came to the front in modernized agriculture seeking for minimizing the soil suffocation with other chemical fertilizers in the bulk size. Nano-fertilizers may represent a way out of shot as they are completely absorbed by plant due to their small size, also it magnifies the benefit to the plant due to its high surface area. Nano-fertilizers are introduced via different way of synthesis methods. In this work, three of new nanocomposites are prepared in nano form via Gamma irradiation from Cobalt 60 source at irradiation dose 5 KGy. These composites which can supply plants with P, Zn elements needs to be revised for their safety usage in agriculture. Three compounds; Zinc oxide, phosphorous and the mixed Zinc–phosphorous elements were prepared in nano-composite forms coated with PVP as a shell and then characterized by HR-TEM, UV and FT-IR to emphasize their new sizes and shapes, then, they were examined for their cytotoxicity in three concentrations (0.5, 1 and 2%) on Vicia faba plants; after 3 h of direct roots treatment. Cytotoxicity test concerned the mitotic index, phase index, abnormal mitosis and the type of the aberrations at each phase. The three tested NPs exerted mito-accelerating effect on root meristematic cells. However, concentration‐dependent genotoxicity was also an evident. The three examined nano-composites may recommend to be used in the lowest examined concentrations to minimize its harm effect on the plant cell and keep their benefits to the environment. It also recommended to count the Zn/P mix NPs over ZN or P separately as it induces an intermediating cytogenetic effect on mitosis apparatus of Vicia faba plant.

γ辐照制备的一些纳米结构聚合物对蚕豆植物的细胞遗传学效应

田间的营养植物是必须的；拥有健康、高产和自我繁殖的植物。新潮的纳米肥料在现代化农业中走在前列，旨在尽量减少与其他散装化学肥料的土壤窒息。纳米肥料可能代表了一种出路，因为它们由于尺寸小而完全被植物吸收，而且由于其高表面积，它也放大了对植物的益处。纳米肥料通过不同的合成方法引入。在这项工作中，三种新的纳米复合材料通过来自钴 60 源的伽马辐射以 5 KGy 的辐射剂量制备成纳米形式。这些可以为植物提供 P、Zn 元素的复合材料需要对其在农业中的安全使用进行修改。三种化合物；氧化锌，磷和混合锌-磷元素以纳米复合形式制备，以 PVP 为壳，然后通过 HR-TEM、UV 和 FT-IR 表征以强调它们的新尺寸和形状，然后检查它们的细胞毒性在蚕豆植物上以三种浓度（0.5、1 和 2%）；直根处理 3 h 后。细胞毒性试验涉及有丝分裂指数、相指数、异常有丝分裂和每个相的畸变类型。三种测试的 NPs 对根分生细胞具有促进有丝分裂的作用。然而，浓度依赖性遗传毒性也很明显。三种检查过的纳米复合材料可能建议以最低检查浓度使用，以尽量减少其对植物细胞的危害影响并保持其对环境的益处。
