| Popis: | Sacred lotus (Nelumbo nucifera) is known to vent pressurized air in the leaf blade through stomata on the central plate of the leaf via the rhizome. This study measured diurnal CH4 emissions from lotus-cultivated in tanks during July and August 2016. CH4 emissions from the central plate of leaves of different age were also evaluated. Average daily CH4 fluxes of lotus-cultivated tanks were 23.1 ± 5.6 and 11.4 ± 6.0 mg C m−2 h−1 during July and August, respectively. Both the diurnal pattern of flow rate and the CH4 concentration of gas emitted from the central plate were similar to those of lotus and other wetland plants. However, the diurnal pattern of CH4 flux of younger leaves was dissimilar to that of tanks with cultivated lotus. Younger leaves exhibited a higher flow rate and greater concentration of CH4 than older leaves. This implies that pressurized air in older leaves is emitted through younger leaves, which contrasts with other plants that emit gas from older leaves or columns via pressurization. |
