Lemongrass Growth, Essential Oil, and Active Substances as Affected by Water Deficit

Environmental stress has a major influence on the growth and quality of medicinal plants. More than half agricultural land worldwide suffers from lack water. In this study, we estimated effect different irrigation intervals growth, yield, essential oil content as well their main compounds lemongrass, Cymbopogon citratus. The objective was to test how much consumption can be lowered without significant impact yield properties. Water deficit led decreases in characteristics including number tillers fresh dry herb yield. addition, relative leaf greenness decreased under water deficit, especially plants irrigated every 20 days. contrast, proline increased with increasing 15 Essential percentage also condition, highest observed However, per plant significantly due decreasing GC-MS analysis identified 31 compounds, mainly geranial neral. Geranial neral 10-day but severity at These results suggest that lemongrass sensitive drought. Nevertheless, represented by active substances improved prolonging intervals. This study recommends 10 days maintain small higher quality. it is recommended conduct more studies improve shortage conditions.
