Abstract

Biljke percipiraju zvuk kao mehanički podražaj koji utječe na promjene u metabolizmu stanice. Dosadašnjim istraživanjima utvrđeno je da zvučni podražaji mogu utjecati na stopu klijanja i povećati rast i razvoj biljaka, tolerantnost biljaka na sušu. Međutim izlaganje biljaka umjetnom zvuku različitih frekvencija može imati i štetne učinke na metabolizam stanice. Stoga je vrlo važno utvrditi koje frekvencije zvuka utječu pozitivno, a koje negativno na rast i razvoj biljaka.. Cilj ovog rada je utvrditi utjecaj zvuka od 1000 Hz na rast biljke i aktivnost antioksidacijskih enzima (peroksidaze i superoksid - dismutaze) kod bosiljka. Dobiveni rezultati utvrđuju negativan utjecaj zvuka frekvencije 1000 Hz na duljinu biljke i lisnu površinu, kao i na masu svježe tvari. Tretman zvukom također je utjecao na smanjenje sadržaja ukupnih proteina u listu bosiljka te na pojačanu aktivnost enzima peroksidaze i superoksid – dismutaze.

Abstract (english)

Plants perceive sound as a mechanical stimulus that affects changes in the metabolism of the cell. Previous research has shown that sound stimuli can affect the germination rate and increase plant growth and development, plant tolerance to drought. However, exposing the plants to artificial sound of different frequencies can also have adverse effects on the metabolism of the cell. Therefore, it is very important to determine which sound frequencies have a positive, and which have a negative effect on the growth and development of plants. The aim of this study was to determine the influence of 1000 Hz sound on plant growth and activity of antioxidant enzymes (peroxidase and superoxide - dismutase) in basil. The obtained results establish the negative influence of sound with a frequency of 1000 Hz on the length of the plant and leaf surface, as well as on the fresh weight of plant. Sound treatment also reduced total protein content in the leaf of the basil and increased the activity of the enzymes peroxidase and superoxide – dismutase.
