Abstract Aquaponic is the combined culture of fish and plants. This experiment was arranged as a factorial in the framework of completely randomized design with two factors of growing system (aquaponics and hydroponics) and plant species (Mentha piperita and Mentha sativa) with 3 replications. The results showed that most growth factors of the two species were higher in hydroponics compared to...
Peppermint (Mentha piperita L.) was grown in a growth chamber under several combinations of temperature and illumination, and the monoterpenes of each leaf pair were analyzed by gas chromatography. Effects on the monoterpenes could be seen in the new leaves after a few days in the growth chamber. Long-day conditions enhanced growth, with a corresponding increase in the total amount of monoterpe...
