EFFECTS OF GINGER EXTRACTS ON TOTAL PROTEIN AMOUNT AND PEROXIDASE ACTIVITY IN SOLANUM LYCOPERSICUM L.

Abstract

Zingiber officinale Roscoe, belonging to the Zingiberaceae family, is a medicinal plant that also spreads in our country. In this research, extracts of Z. officinale rhizomes were prepared with different solvents (ethanol, methanol, distilled water, DMSO). Zingiber rhizome extracts were sprayed on the leaves of rio grande and marmande varieties of 10-12 weeks old Solanum lycopersicum plantlets. Total protein amount and peroxidase activity were examined by spectrophotometrically 24 and 48 hours after the application. According to the results, it was determined that the maximum increase in the total protein amount compared with the control group was 31.31% and 25.53% in marmande and rio grande varieties in ginger rhizome extract prepared with methanol, respectively. The increase in peroxidase activity was determined as 144.14% and 124.85% in marmande and rio grande varieties in ginger rhizome extract prepared with ethanol, respectively. As a result of our research, it was determined that rhizome extracts of Z. officinale can be used as natural plant activator.
