EFFECTS OF NANO-SiO2, Nd2O3 AND CeO2 ON THE GROWTH OF Paramignya trimera (Oliv.) AND Paris polyphylla

The study investigated nano-SiO2, Nd2O3, and CeO2 materials applied as fertilizer for Paramignya trimera (Oliv.) Guill plants. (Rutaceae) and Paris polyphylla. The cultivation results indicated that the individual uses of nano-SiO2, Nd2O3, and CeO2, respectively, induced stem and root growth of P. trimera and P. polyphylla. The plant height, root length, stem, and root weight of the mixture of Nd2O3 and SiO2 or CeO2 and SiO2 exposed plants were greatly higher than those of the individual nanomaterial exposed plants. The extraction experiments indicated that ostruthin, a valuable medicinal substance, accumulated in the roots of the P. trimera rather than in its stems. The ostruthin content in the root of the Nd2O3 exposed P. trimera was also greatly higher than that in the control and SiO2 exposed plants. Gracillin, an important medicinal compound, content in the rhizome of the CeO2 exposed P. polyphylla was also greatly higher than that in the SiO2 exposed P. polyphylla.
