TS Inter 2nd Year Botany Notes Unit 6 Plants, Microbes and Human Welfare
→ Plant breeding is a technique of manipulation of plant species in order to create desire plant types that are better suited for cultivation, give better yields and are disease resistant
→ Green revolution was dependent mainly on plant breeding techniques.
→ Methods of breeding for disease resistance are
- Conventional breeding method
- Mutation breeding.
→ Insect resistance in host crop plants may be due to morphological, biochemical or physiological characteristics.
→ Biofortification is the process of developing crops with higher levels of vitamins, minerals, proteins and healthier fats to improve public health.
→ Single Cell Protein (SCP) is an alternate protein source for animal and human nutrition from certain Microorganisms like Spirulina.
→ Techniques of tissue culture and somatic hybridisation offer vast potential for manipulation of plants in vitro to produce new varieties.
→ Microbes are the major components of biological systems on the earth.
→ Various types of microbes are protozoa, bacteria, fungi, viruses, viroids and prions.
→ Microbes in household products are common experience of everyday life.
→ The common products obtained by the use of microbes are curd, dough, toddy, cheese eta
→ Microbes are used to produce industrial products like lactic acid, acetic acid and alcohol which are used in a variety of processes in the industry.
→ Antibiotics are chemical substances which are produced by some microbes and can kill or retard the growth of the disease causing microbes.
→ Microbes play a major role in sewage treatment
→ Biogas produced by microbes is used as the source of energy in rural areas.
→ Microbes can also be used to kill harmful pests. This process is referred to as biocontrol. There is a need for the aggressive use of biofertilisers in place of chemical fertilisers.
→ Microbes, play an important role in the welfare of human society and have been put to adverse use.
