The effect of shading on density and size of glandular trichomes in artemisia cina tetraploid, the source of anti-cancer artemisinin

Abstract

Artemisinin is a sesquiterpene lactone found in Artemisia cina having many medicinal properties. Artemisinin produced and stored in Glandular trichomes The purpose of this study was to determine the effect of shade 0%, 50% and 75% on the density and size of glandular trichomes and the content of artemisinin in A.cina tetraploid plants. The shade treatment significantly affected the density and size of glandular trichomes and the content of artemisinin in Artemisia cina tetraploid. 50% shade treatment showed the highest density of Glandular trichome, the width of glandular trichomes, and Artemisinin content. The results of the correlation analysis show that there is a very significant relationship between the density of glandular trichomes and the content of artemisinin.
