A genus of the family aponogetonaceae. Aquatic rosette plants with underwater leaves and some species with floating. The leaves have long petioles, the leaf blades of the underwater leaves are thin, translucent. The shape and color of them makes aponogetons desirable plants in the collection. Most of them grow well in nutrient soil with clay additives. The light is bright. However, as in nature aquarium aponogeton in the winter months, stop growing, drop their leaves. Often there is only a tuber with a supply of nutrients. Inexperienced aquarists believe that something unusual is happening to plants, they begin to transplant them from place to place, and often throw them away. Instead, you should try not to disturb the plant, reduce the temperature by 5-10 °C. in the Spring, a. will resume its growth.
Propagated by a, exclusively seeds. It should be noted that many plants are cross-pollinated, so it is necessary to reproduce at least two bushes. Pollen from the inflorescence to the inflorescence is transferred by a brush. Large seeds, falling to the bottom, germinate in 2-3 days.
The exact definition of species by an Amateur aquarist is difficult. The fact is that a considerable number of aquarium hybrid aponogetons have now been added to the numerous species.
Wavy aponogeton (Aponogeton undulatus Roxburgh)
India. Leaves on long thin petioles, up to 40 cm long. Underwater leaves with blunted apex, broadly colanceolate, strongly wavy, on a translucent leaf blade a characteristic pattern of veins is visible. The floating leaves are elongated-oval, glossy. In aquariums, the most common variety of a. wavy, in which young plants appear from a nodule at the end of a long shoot. Stronger seedlings with developed leaves are separated from the mother. Seeds almost does not reproduce, because very reluctantly blooms.
Aponogeton curly (Aponogeton crispus Thunberg)
sri lanka. Leaves up to 50 cm long, only underwater, narrow-lanceolate, wavy on the edge. The Botanical literature indicates that plants of this species have a reddish tinge in the color of the leaves. In hybrids with many close species, the leaves are light or dark green, without red tones. The temperature in the range of 20 to 25 °C. odnorazovyj Peduncle, white or slightly purple. The plant is self-pollinating.
Madagascar aponogeton (Aponogeton madagascariensis (Mirbel) Van Bruggen)
Madagascar. Madagascar aponogeton also called other species common on the island-Aponogeton fenestralis, Aponogeton henkelianus, Aponogeton bernerianus.
The plant is complex in culture, but deserves attention due to the peculiarities of the structure of the leaves. The leaf blade of the broad-oval leaves consists of only longitudinal and transverse veins and resembles a green grid.
Contain the plant in separate aquariums at 18-25° C in soft fresh water, pH 6-7. The lighting is dim. The soil consists of 1 part clay, 1 part charcoal and 7 parts sand. Peduncle 2-6-carob, white or pink.
