Abstract

The interaction of CuO nanoparticles (nCuO), a potential nanopesticide, with the growth hormone indole-3-acetic acid (IAA) is not well understood. This study aimed to evaluate the nutritional components in seeds of green pea (Pisum sativum) cultivated in soil amended with nCuO at 50 or 100mgkg, with/without IAA at 10 or 100μM. Similar treatments including bulk CuO (bCuO) and CuCl were set as controls. Bulk CuO at 50mgkg reduced seed yield (52%), compared with control. Bulk CuO at 50mgkg and nCuO at 100mgkg, plus IAA at 100μM, increased iron in seeds (41 and 42%, respectively), while nCuO at 50mgkg, plus IAA at 100μM reduced boron (80%, respect to control and 63%, respect to IAA at 100μM). IAA, at 10μM increased seed protein (33%), compared with control (p≤0.05). At both concentrations IAA increased sugar in seeds (20%). Overall, nCuO, plus IAA at 10μM, does not affect the production or nutritional quality of green pea seeds.

摘要

氧化铜纳米颗粒(nCuO)作为一种有潜力的纳米农药,其与生长激素吲哚-3-乙酸(IAA)的相互作用尚未得到很好的理解。本研究旨在评估在添加了 50 或 100mg/kg 的 nCuO(有/无 10 或 100μM 的 IAA)的土壤中种植的绿豌豆(Pisum sativum)种子中的营养成分。类似的处理包括大块氧化铜(bCuO)和 CuCl 作为对照。与对照相比,50mg/kg 的大块 CuO 降低了种子产量(52%)。50mg/kg 的大块 CuO 和 100mg/kg 的 nCuO,加上 100μM 的 IAA,增加了种子中的铁含量(分别为 41%和 42%),而 50mg/kg 的 nCuO,加上 100μM 的 IAA,降低了硼含量(分别为 80%,与对照相比和 63%,与 100μM 的 IAA 相比)。与对照相比(p≤0.05),10μM 的 IAA 增加了种子中的蛋白质含量(33%)。在这两种浓度下,IAA 都增加了种子中的糖含量(20%)。总的来说,nCuO 加上 10μM 的 IAA 不会影响绿豌豆种子的产量或营养品质。
