ICP-MS based metallomics and GC-MS based metabolomics reveals the physiological and metabolic responses of Dendrobium huoshanense plants exposed to Fe₃O₄ nanoparticles.

ABSTRACT: It is found that the growth of Dendrobium huoshanense was dependent on Fe₃O₄, while the bioavailability of plants to ordinary Fe₃O₄ was low on the earth. In order to improve the growth, quality and yield of D. huoshanense, we used Fe₃O₄ NPs (100 or 200 mg/L) that was easily absorbed by plants as nano-fertilizer to hydroponically treat seedlings of D. huoshanense for 3 weeks. Fe₃O₄ NPs induced not only earlier flowering and increased sugar content and photosynthesis, but also stressed to plants, increased MDA content and related antioxidant enzymes activities. Inductively Coupled Plasma Mass Spectrometry (ICP-MS) revealed that Fe₃O₄ NPs caused a significant accu
