Plant Tissue Culture PPT

Tissue Culture  Banana Cultivation - In Tissue culture banana cultivation the banana suckers should be kept under shade and water sprayed over them 4-5 times everyday. This should be done for 3-4 days.

Planting
Pits of 3x3x3 feet should be dug and the surface soil should be placed in the bottom of the pit along with composed farmyard manure.

Furadon granules at 10-15g per pit may be mixed with the soil and farm yard manure. Light irrigation should be given for 3-4 days.

If the planting is done during the monsoon Carbendazim fungicide at 5 gram per litre of water may be applied to avoid seedlings rotting disease.

Phosphate and potassium fertilizers should be applied within five months after planting the suckers.

While planting the suckers, the pits should be manured by 1/5th of recommended phosphatic fertilizer along with 1/5th of ammonium sulphate as nitrogen fertilizer.

Equal quantity of ammonium sulphate should be applied further on the fifteenth day. The remaining nitrogen and phosphatic fertilizers and the full dose of recommended potash should be applied in four equal splits at monthly interval.

Micro-nutrient fertilizers should be applied in two equal splits during third and fifth month of planting.

Zinc (Zn) and Copper (Cu) micro-nutrients should be applied without fail, particularly in sandy soil field and the fields where previously banana was cultivated.

Ferrous sulphate should be given as foliar spray for the fields having `calcareous' soils, four times during third and fifth month at an interval of 10-15 days.

Increasing weight
Proper plant growth promoting enzymes should be sprayed. After opening of last hands of the bunch NKP foliar grade fertilizer at 2g/litre of water should be sprayed four times at 15 days interval over the bunch for increasing the weight. S.

Banana Tree Information - The Banana tree is not actually a true tree; it is an herb in the genus Musa. Due to its tall size and structure, a Banana plant is however commonly referred to as a Banana tree. The Banana tree is cultivated in warm climates all over the world for its fruit and archaeological and palaeoenvironmental findings suggest that the banana tree have been cultivated by humans for at least 7000 years, possibly 10 000 years in Papua New Guinea.

The Banana tree originates from tropical environments in South-East Asia. The upright part of the Banana tree is very similar to the stem of a true tree and is an example of a so called pseudostem. The pseudostem of the Banana tree can grow up to 2-8 metres in height. (Different cultivars have different maximal heights.) From the pseudostem, large green leaves that can reach a size of 3.5 metres will grow.

Each pseudostem will produce one bunch of bananas and then die, and be rapidly replaced by new pseudostem. The rhizome base of the plant, from which the pseudstems grow, is called a corm. A corm is a swollen underground stem in which a plant can store energy that allows it to survive during harsh conditions, e.g. during a drought. The banana tree corm is perennial and can keep on producing pseudostems for 15 years or even longer.

The elongated fruit produced by the banana tree is not a true fruit, it is a false berry. False berries are accessory fruits that distinguish themselves from true berries by having an inferior ovary. Other examples of false fruits are cucumbers, squashes, pumpkins, watermelons, blueberries and blackcurrants. The banana tree produces clusters of such false berries and one tier can contain up to 20 false fruits. A banana tier is also known as a banana hand. Each bunch will typically contain from 5 to 20 hands. One single banana tree bunch can weigh up to 50 kilograms.

As mentioned above, the leaves of the banana tree can grow up to 3.5 metres in length. Since they are not only large, but also strong, flexible and waterproof, they are used in many different ways in regions where the banana tree is common. One of the most well known ways of making use of the banana leaf is naturally as food wrap. Central American tamales are for instance often steamed inside banana leaves, and Chinese xongzi is sometimes prepared using banana leaves instead of bamboo leaves. The imu (underground oven) used in traditional Hawaiian Kalua cooking is often lined with banana leaves.

The flower of the banana tree is often referred to “banana heart” and “banana blossom”. In Indian and South-East Asian cuisine, this part of the banana tree is frequently used for soups and curries. It can also be eaten raw with dip sauces. Another part of the banana tree that is often used for human consumption is the banana trunk. In Bengali and Kerala in India, as well as in Burma, the tender core of the banana tree trunk is used to extract a juice. This juice is used as a traditional folk remedy against kidney stones.
