This research was managed to identify the effects of the different seed quantity (5, 10, 15 and 20 kg.ha–1) and row interval (15 and 30 cm) on the yields and the volatile oil components of fennel (Foeniculum vulgare Mill.) under the Harran Plain conditions, during 2013 and 2014 years. The study was established according to the split plot in randomised complete block design. Seed and volatile oil yields, volatile oil ratio and volatile oil components were importantly affected seed quantity and row interval. The transaction of 15 cm × 10 kg.ha–1, the highest seed and volatile oil yield were taken, was determined to be the most suitable. The trans-anethole was taken the primary component under all transactions and it was changed to depend on the row interval and seed quantities.

Abstract Background Asarum heterotropides Fr. Schmidt var. mandshuricum (Maxim.) Kitag. is an important medicinal and industrial plant, which is used in the treatment of various diseases. The main bioactive ingredient is the volatile oil having more than 82 identified components of which methyleugenol, safrole, myristicin, and toluene account for about 70% of the total volume. As a sciophyte plant, the amount of light it absorbs through leaves is an important factor for growth and metabolism. Results We grew Asarum plants under full, 50, 28, and 12% sunlight conditions to investigate the effect of different light irradiances on the four major volatile oil components. We employed de novo transcriptome sequencing to understand the transcriptional behavior of Asarum leaves regarding the biosynthetic pathways of the four volatile oil components, photosynthesis and biomass accumulation, and hormone signaling. Our results demonstrated that the increasing light conditions promoted higher percent of the four components. Under full sunlight conditions, cinnamyl alcohol dehydrogenase and cytochrome p450719As were upregulated and led the increased methyleugenol, safrole, and myristicin. The transcriptomic data also showed that Asarum leaves, under full sunlight conditions, adjust their photosynthesis-antenna proteins as a photoprotective response with the help of carotenoids. Plant hormone-signaling related genes were also differentially expressed between full sunlight and low light conditions. Conclusions High light induces accumulation of major bioactive ingredients A. heterotropides volatile oil and this is ascribed to upregulation of key genes such as cinnamyl alcohol dehydrogenase and cytochrome p450719As. The transcriptome data presented here lays the foundation of further understanding of light responses in sciophytes and provides guidance for increasing bioactive molecules in Asarum.
