Abstract
The influence of pot size on plant height, stem diameter, dry leaf biomass, essential oil content, and composition of Eucalyptus citriodora was investigated in this experiment. Both the physical and the chemical properties of pot-grown plants were significantly affected by pot size. Plants grown in larger pots were generally taller, had thicker stems and wider canopies, grew more branches, and produced more leaves that were larger than plants grown in smaller pots. The highest essential oil concentrations (∼ 1.2%) were observed in plants grown in 1-liter (20-cm diameter) and 5-liter (11 cm diameter) pots. Essential oil composition was fairly similar for all pot sizes. We conclude that Eucalyptus citriodora can be grown in pots, preferably in 10- or 5-liter pots, and thus provide fresh leaves on a daily basis.
