Cloning Plants and Hydroponic Cultivation

Cloning is not a new technique nor does it require complicated laboratory equipment. One does not need an advanced degree in biology or genetic engineering to understand and do cloning. People who have very little formal education in science can easily perform cloning. Farmers and gardeners have been doing it for thousands of years since agriculture was invented. Nature has been doing it for billions of years since the first single celled organisms learned how to reproduce asexually. Multiple generations of genetically identical organisms can be reproduced asexually through the process of cloning. These cloned organisms have the same exact set of genes as their parents.

Compared to cloning animals, cloning planst is very easy to do. Vegetative parts of plants such as stems and leaves can be cloned given the right conditions. The undifferentiated cells that are found on the tips of roots are also ideal for multiple cloning. However, other vegetative and fully mature parts such as stems may also be used for this purpose. The simplest method is to simply cut a callus or undifferentiated component of a plant and plant it directly in the soil. Some plants such as cassava can easily be cloned by cutting their stems and planting the cut pieces in the soil. The seedlings usually develop within a few days or a few weeks. Newly formed but genetically identical plants will eventually grow.

However, it should be noted that not all species of plants are easy to clone. Some plant species require special and meticulous attention for them to be successfully cloned. Some plants that have high agricultural and horticultural value oftentimes need special care and attention. Plants that have high yields, high resistance to diseases, priced for their decorative value and rarity, and have medicinal use are very desirable. Unfortunately, some of these plants are hard to come by. Oftentimes, the most cost-effective and efficient way to reproduce these plants is through cloning. Cultivating cloned plants is usually very convenient when done using hydroponic systems.

Using hydroponic systems is the ideal way of cultivating plants indoor. Hydroponic systems allow for the precise amount of nutrients, light, hormones and water that is needed by cloned plants. The situation can be particularly tedious for some cloned varieties. Another main advantage of hydroponic systems is that they can be set up in such a way that the growth media can be made sterile, preventing plant infections. The growth and development can be precisely controlled and monitored. The consumption of water and nutrients is very efficient when it comes to hydroponic systems.
