- Abstract
The aim of this study was to determine the season that promotes the highest production and best quality of marjoram (Origanum majorana L.) essential oil in summer and winter transplantations. Two experiments were performed in a protected cultivation, the first with transplanting in summer and the second with transplanting in winter, with a completely randomized design with four treatments, corresponding to the seasons of the year. Content, yield, and chemical composition of the essential oil were determined. The essential oil was extracted by hydrodistillation and analyzed by gas chromatography. In the summer transplanting, the essential oil content and yield were higher in the summer and spring seasons. In the winter transplanting, the essential oil content was higher in the summer season and the yield in summer and spring. Carvacrol was the major component of marjoram essential oil regardless of harvest and transplanting season. Of the other main compounds, only terpinolene was detected in all samples analyzed, with the other essential oil components varying between transplanting and harvest seasons. The highest production of marjoram essential oil is obtained in summer and spring harvests from plants transplanted in summer and winter. Carvacrol was the major component of marjoram essential oil and the other main components vary among seasons.
