Effects of silver nanoparticle on Morinda officinalis How

Abstract

Nanosilver is a form of silver metal particles, extremely small nano-sized particles, about 1 to 100 nm. Nanosilver solution can be used to treat the soil before sowing or planting trees to control pathogenic microbes and improve plant growth and development. Nevertheless, the study on the effects of silver nanoparticles remains limited. Therefore, the aim of the current study was to examine the effects of nanosilver concentration on the growth and development of Morinda officinalis How grown in Ba Che district, Quang Ninh province. The silver nanoparticle solution (2 to 10 ppm) mixed with the extract of sour star fruit was sprayed on the seedlings of M. officinalis How and their growth and development were measured. The results showed that the use of nano-silver solution affected the growth and development of Morinda officinalis How. The study successfully prepared a 500 ppm nanosilver solution by a chemical reduction method with reducing agent extracted from the sour star fruit. It has the dual effect of both promoting growth and development as well as producing the best tuber quality for Morinda officinalis How grown in Ba Che, Quang Ninh at 6 ppm.
