Introduction:
It is a method of growing isolated cell or tissue aseptically achieved by mechanical or enzyme method and culture it on a nutrient medium with required optimum conditions for it is growth and it is widely used to produce number of same copies of single plant and it is known as “micro propagation”.
The basic principle is the isolation of large number of living cells and cultures it on a suitable nutrient medium. Many plant cells have the ability to regrow a new plant called toti-potency. Single cells of plant, leaves, stems or roots can also used to generate a new plant on culture medium by giving required nutrients and plant hormones.
History of Tissue Culture technique in Pakistan:
Tissue culture method in Pakistan was started before ten years ago and this technique was truly new for most of the research labs and horticulture universities. From 1990 onwards the number of plant tissue culture lab were introduced where public and private sectors comes and invest in this new field of science. Now this field emerged rapidly that now everyone knows about the plant tissue culture and it is advantages in different science departments. Now plant tissue culture technique successfully emerging in Pakistan in different the field of establishment, to get varieties of new plant traits, to reduce plant diseases and many more.
Advantages of plants tissue culture:
There are certain advantages of plant tissue culture methods of micro-propagation, such as:
• Through plant tissue culture, plants have ability to form number of same copies of a plant within a short period of time. It may produces fruits, flower or other different types of traits.
• To produce number of copies of plant within a short period of time.
• ...

...lable known as cardinal. Desiree, and diamant. This research was done at Pak labs. The forum is working for huge variety of different crops.
The plants of potatoes were washed with detergents and after that with double distilled water for sterilization and free from bacterial contamination. Then explants were placed into the agar medium with the combination of GA3 with different concentrations. After three to four weeks results were shown of formation of roots and shoots
Conclusion
Plant tissue culture technique is promoting day by day in Pakistan. Because it has number of applications in many different fields like in food industry, pharmaceutical industry, and also in agricultural industry. The main benefit of this technique is the micro-propagation process which takes less time and gives large quantity of crop on commercial level with free from pathogens.
The focus of this lab on planaria regeneration and development. Having been taught the gradient of morphogen and there were many experiments testing this possible phenomenon of regrowth. In a planarian there is a single adult stem cell type called the neoblast. Neoblast are abundantly present throughout the body and it divides continuously. This neoblast has the ability to regenerate different cell and organ types in the planarian, from the brain, digestive system, the sensory system to even the reproductive system. With this continuous stream of continuous division of cells it allows the cells of the planarian to be rapid in self-renewal of the entire
Grafting as a means of managing disease and increasing yield has only recently begun to take off in much of the western world. In Asia, however, grafting has been an important agronomic technology since the 1920’s. (Kubota) Farmers in Asia first started grafting cucurbit species and then started grafting solanaceous plants such as eggplant and tomato. Producers in Japan and Korea readil...
1Germination can be defined as the process of seeds, develop into new plants. In spite of being changeable according to its species, there environmental conditions that needs to be supplied such as temperature, ph and sunlight.1The first process is when water is plentiful, the seed fills with water in a process called imbibiton. In this process seed starts to grow a root. As the plant grows leaves to obtain sunlight. After this point, plant will continue to develop and make its own food by photosynthesis. In order to grow a plant stronger and faster, over the time, people developed different ways. One of these ways is applying fertillizer directly to the plant. Fertillizer is mostly beneficial and widely used so that plants may
Plant development is done through two key procedures known as photosynthesis and respiration. During the process of
Plant cell division: a cell plate develops across the centre of the cell, forming a new cell wall between the 2 cells
Selective breeding is carried out by both commercial and hobby breeders. Breeding must be carried out within the same species, if it is carried out with two different species then they can’t breed together. Animals that are bred are known as breeds, whereas plants which are bred are known as varieties or cultivars. The outcome of cross breeding animals and crossbreeding plants are called hybrids. There are two types of selective breeding which i...
Plants are the life forms from the Kingdom Plantae. They reproduce sexually and asexually, they can reproduce with only one parent. The plant lifecycle begins with a seed. It can grow with the right amount of sunlight, water, and the air. Next, the seed sprouts and the seed grows its roots, stem, leaves, flowers and more seeds. The leaves that are formed from the seeds stem are called seedlings. As the seed slowly becomes a plant it sheds seeds and the cycle continues.
Genetic cloning may, to the public, be a relatively new technology but in reality scientists have been trying to accomplish this feat for hundreds of years. When used the right way and for the right reasons, genetic cloning for plants, animals, and humans can be used for the benefit of all.
...ince, there is a need to use for advanced novel methods of culturing plant to furnish new means for quickly propagating,conserving of endangered species and also introducing exotic plants. The production of high quality planting material of exotic nature propagated from vegetative parts through tissue culture has created new opportunities in global trading. The exotic plants are advantageous for farmers;growers; nursery owners & rural employment. As exotic plants are restricted to their natural environment; the main benefit of tissue culture technology lies on production of high quality & uniform planting material that can be multiplied on a year round basis. The plant selected for such purpose is Stevia rabuadiana Bertoni. Objectives of study:
Tissue culture allows for the clonal propagation of plant (production of multiple copies of the same genotype).
(4) Cut small pieces of callus (0.5 gm) fresh weight and subculture on the same fresh medium for proliferation.
Take cuttings for clones before you move plants from vegetative grow area to the flowering area. Low branches are cut to increase air circulation under the green canopy. Rooted clones are moved to the vegetative growth area, and new clones are started in the cloning area using the low branch cuttings. Each cycle of growth will take from 4-8 weeks, so you can constantly be growing in 3 stages, and harvesting every 6-8 weeks.
Cloning involves the process of producing a cell, tissue, or even a complete organism from a single cell. The DNA sequence is replicated from the original biological unit. There are two types of cloning, natural and somatic cell transfer. Cloning of plants or bacteria is natural. Plants have been duplicated for many years by replicating itself and growing. Bacteria are cloned through the process of mitosis, division of a single cell. Somatic cell transfer cloning is completed when cells are copied and transferred. Genes maintain genetic codes that hold our inherited information. Gene mapping is used to establish order.
Micropropagation - This method uses a mature cell to dedifferentiate into callus tissue. The two processes in micropropagation are known as organogenesis and somatic embryogenesis. Organogenesis develops shoot buds into apical meristems, while somatic embryogenesis forms non z...
