Plant Tissue Culture Applications

Applications of Plant Tissue Culture Application in Research Work Tissue culture techniques have helped in research work variously: By culturing different tissues on artificial media, knowledge about requirements of various chemical substances (minerals) necessary for the growth of those tissues is found. Organogenesis has been studied by inducing formation of roots, shoot tips, etc. From callus on nutrient mediums. Tissue ...

Plant Tissue Culture

Plant Tissue Culture The term plant tissue culture is commonly used to describe in vitro (in glassware) and aseptic cultivation of any plant part on a nutrient medium. Tissue culture technique has provided an efficient tool for modern plant breeding. Plant tissue culture technology is based on three fundamental principles. The plant part (explant) must be isolated from the rest ...

Abscisic Acid- ABA

Abscissic Acid (ABA) Abscissic acid (ABA) is a ubiquitous plant hormone that inhibits growth of vascular plants. It has been detected in mosses but appears to be absent in liverworts. Several fungal genera make abscissic acid as a secondary metabolite. In algae and liverworts, a compound similar to abscissic acid called lunularic acid appears to play physiologic role similar to ...

Ethylene

A Volatile Growth Inhibitor Ethylene, a growth inhibitor, is the simplest known olefin. It is lighter than air under physiological conditions. It is flammable and readily undergoes oxidation to ethylene oxide, and can be hydrolyzed to ethylene glycol. In most plant tissues ethylene can be completely oxidized to CO2. Ethylene is released easily from the tissue and diffuses in gas ...

Cytokinins

Cytokinins After the discovery of auxins and gibberellins and their influence on growth and development, efforts were diverted to find the factors that would stimulate plant cells to divide. These efforts led to the discovery of cytokinins, they were found to effect other physiological and developmental processes as well. Kinetin Folke Skoog tested many substances for their ability to stimulate ...

Gibberellins

For many years after the discovery of auxin, plant scientists attributed all the development and plant processes taking place in plants to auxin. In 1950s another groups of growth substances, the gibberellins, was discovered. The main effect of the hormone was tallness in plants and chemically it was recognized as gibberellic acid (GA). Later many more, about eighty gibberellins were ...

Ectocarpus

Occurrence Ectocarpus is a brown alga. It is abundantly found throughout the world in cold waters. A few species occur in fresh waters. The plant grows attached to rocks and stones along coasts. Some species are epiphytes on other algae like members of Fucales and Laminaria. Ectocarpus fasciculatus grows on the fins of certain fish in Sweden. Ectecarpus dermonemcnis is ...

SOIL EROSION

The wearing away of the soil by wind, water, snow or gravity is called soil erosion. Climatic, topographic. biotic, edaphic, and geologic factors cause the soil erosion. Climatic factors: Wind and rainfall are climatic factors. Topographic factors: Length of slope is a topographic factor. Biotic factors: Uncontrolled grating of vegetation by animals and cutting of vegetation by man are biotic ...

Batrachospermum

Occurrence Batrachospermum is fresh water alga. It is found in clear, cool and running streams. Deep water plants are dark violet or reddish in colour. But the shallow water species are olive green. The intensity of light changes the colour of pigments. The thallus is attached to the substratum. General structure Vegetative structure Tha:lus of adult plant is soft, thick, ...

DESERTIFICATION

Spreading of deserts to the green areas is called desertification. Desertification occurs due to human activities. Desertification occurs in grasslands and forests. Earlier, vegetation was present there. But over exploitation of these natural resources changes them deserts. These are not natural deserts. But they arc man made deserts. Deserts are characterized by few vegetation and arid land. The ruins of ...
