Effect Biosynthesis of fenugreek leaves nanomaterial on some plant's germination using saline water

Abstract

The synthesis of new, low-cost nanomaterials that do not cause harm to the environment is of great importance in modern Science. In addition to the importance of plant use in medical purposes and the active substances they contain, this research includes the synthesis of nanomaterials from medical plant (fenugreek) Trigonella foenum extract for tolerating irrigation with saline water. The extract of the dried and ground leaves of the T. foenum plant was taken, centrifuged, filtered, and then dried. The resulting material was tested by the X-ray Diffract meter (XRD) and the Atomic Force Microscope (AFM) examining to ensure it was on the nanoscale. Aqueous dilution at a ratio of 1: 1 used to irrigation seeds of the aromatic plants (Apium graveolens and Lepidium sativum) with saline water 0.05 g / l. The germination ratios, the extreme length and the plumular were calculated after 3, 5, 7 and 10 days of germination. The germination rates were superior to the treatment with a nanomaterial and saline water mixture for 98.5% in A. graveolens and 97.2% in L. sativum. Saline water treatment showed 75% for A. graveolens and 78% for L. sativum. The extreme length reached 14.5 cm for the A. graveolens and 11.3 cm for the L. sativum in the mixture treatment after 10 days. Saline water treatment gave 6.3 cm and 8.5 cm, respectively. The plumular measurements were similar to the radical results. These results proved the synthesis of a natural bio-nanomaterial that is easy to prepare, low in cost and have a stimulating effect on germination, growth and tolerance irrigation with saline water. This improves our ability to utilize water resources and propagation methods for aromatic and medical plants.
