Nutrient medium is solidified by adding NAA Sodium hypochlorite Agar Explant 2. Inoculation of explant is carried out in Autoclave Laminar air flow chamber Incubation chamber Septic condition 3. Nutrient medium is sterillized with the help of Laminar air flow chamber Incubation chamber Pasteurisation Autoclave 4. Any part of the plant which is introduced to culture medium to grow into full fledged plant or| organs in vitro is called Propagule Clone Plantlet Explant 5. A synthetic seed consists of Somatic embryo without protecting capsule Only sodium alginate capsule Somatic embro with capsule made with mercuric chloride Somatic embryo, nutrient mediu and capsule made with sodium alginate 6. From a virus infected vegetatively propagated plant, virus free plants can be produced by Embryo culture Anther culture Shoot – tip culture Organ culture 7. “In vitro” tissue culture is based on the principle of Cellular asepsis Cellular totipotency Inoculation and incubation Organogenesis 8. Which of the following need not to be used while preparing a basal nutrient medium Sugars Vitamins Growth regulators Amino acids 9. Regeneration of complete plantlets from callus does not require the pressence of this component in the culture medium NAA Kinetin Sodium hypochlorite IAA 10. The tissue used by Steward from carot plant to demonstrate totipotency is Secondary xylem from stem Secondary xylem from root Secondary phloem from root Heart wood from stem 11. Which of the following provides energy for tissue growth “invitro” Macro and micronutrients Amino acids and vitamins Growth regulators Carbohydrates 12. Plantlets developed by another culture can be prevented from dessication by Keeping them in autoclave Growing them in small pots with compost Growing them in medium rich in growth hormones Covering them with polythene bags 13. Mismatch of the following is Shoot tip culture – Production of virus free plants Somaclonal variations – Variations due to gene recombination Synthetic seeds – Alginated embryoids None 14. The following provides aeration for tissue growth “invitro” Macro and micronutrients Amino acids and vitamins Growth regulators Non – absorbent cotton of culture vessels 15. Rhizogenesis and caulogenesis are initiated by Auxin and Cytokinin 3) Gibberellin and Cytokinin 2) Auxin and Gibberellin Cytokinins and Zeatin Loading … Related posts: Strategies for enhancement in food production Test-4 Strategies for enhancement in food production Test-5 Strategies for enhancement in food production Test-6 Strategies for enhancement in food production Test-8 Strategies for enhancement in food production Test-9 Powered by YARPP.
