Sexual propagation

In the wild, many aquatic plants reproduce sexually, much like terrestrial plants, by producing flowers and seeds, or spores. When a flower is pollinated with the pollen from another plant of the same species, a viable seed is produced with the potential to grow into a new plant. The combination of genetic information from the two parent plants will produce a genetically different

Right: The flowers of some aquarium plants are quite stunning in design. Spathiphyllum wallisii produces blooms that are robust and well able to withstand environmental pressures, both above and below the water.

Above: The flowers of this Bacopa monnieri are produced above water and will be fertilized by insects, much like terrestrial plants. This plant can also be propagated by cuttings and side shoots.

plant. Sexual propagation requires two or more plants to produce flowers above the water surface, and although this does occur in the aquarium if the environmental conditions are favorable, it is difficult to control. First you must encourage the plants to produce the strong aerial stems on which the flowers will be borne, so provide a well-ventilated area above the aquarium and below the light unit. Most plants that can produce aerial flowers will eventually do so, although this does depend on the water level, which may have to be lowered for some species. Most stem plants and lilies will produce flowers in the aquarium under the right conditions.

Once the flowers are produced they must be pollinated. In nature, insects are responsible for the transfer of pollen, both in aquatic and terrestrial plants, but to carry out the process artificially, transfer pollen from the stamen (male) to the stigmas (female) using a fine artist's brush. In some cases pollen can be used to fertilize the same plant from which the pollen was taken, thus creating seeds with an identical genetic makeup.

If pollination is successful and seeds are produced, plant them up Immediately, as often they do not last long before starting to germinate. In many cases, it is better to plant the seeds in damp soil, rather than submerged in water, and grow them out of water until the seedlings are about 4 in (10 cm) tall. Then you can transfer them to aquarium conditions.

Propagating aquarium plants from seeds

Propagation Aquarium

The seeds of most aquatic plants are quite delicate and need not be planted deep in the substrate. Simply sprinkle them onto damp soil.

As the seeds begin to sprout, add a little water, so that the leaves are just covered. Some aquatic plants can be grown from seed above water, but they may not acclimatize quickly to the aquarium.

As the new plants grow, raise the water level so that the leaves remain covered. Once the seedlings have at least four or five leaves and are about 4 in (10 cm) high, they can be moved into the aquarium.

Barclaya Longifolia

Above: Barclaya longifolia (the orchid lily) can be propagated only by seed. At this stage, the seeds are ready to be removed and sown in damp substrate. Most should sprout and produce new plants, which can eventually be moved into an aquarium.

The COMPLETE guide to Aquariums

The word aquarium originates from the ancient Latin language, aqua meaning water and the suffix rium meaning place or building. Aquariums are beautiful and look good anywhere! Home aquariums are becoming more and more popular, it is a hobby that many people are flocking too and fish shops are on the rise. Fish are generally easy to keep although do they need quite a bit of attention. Puppies and kittens were the typical pet but now fish are becoming more and more frequent in house holds. In recent years fish shops have noticed a great increase in the rise of people wanting to purchase aquariums and fish, the boom has been great for local shops as the fish industry hasnt been such a great industry before now.
