Question

the plant that is not possible vegetative propagation​

Answer 1

Answer:

Explanation:

Crop species, which do not produce seeds like pineapple, banana, strawberry, fig, jasmine, hibiscus, bougainvillea, etc., cannot multiply by this method. It is also called 'vegetative propagation'. The vegetative parts of a plant like leaf, stem, root or their modified forms are used for propagation.

Answer 2

Answer:

Vegetative propagation can be most effectively done under controlled environment. Therefore, photoautotrophic micropropagation will replace the conventional vegetative propagation method, provided that the production cost per propagule is comparable with that in the conventional vegetative propagation in greenhouse. Propagation efficiency and costs for maintaining stock plants are variable, being affected by the weather conditions in greenhouse vegetative propagation. Thus, vegetative propagation under a controlled and pathogen free environment (i.e., photoautotrophic micropropagation) can be feasible. The production costs can be reduced in photoautotrophic micropropagation, but energy and mass balance in photoautotrophic micropropagation systems need to be analyzed for further improvement of the production efficiencies.

Potential applications of techniques and methods developed for photoautotrophic micropropagation include using photoautotrophic micropropagation as a research tool of testing phenotypes (such as specific resistances) of genetically engineered plantlets under aseptic, controlled environment conditions as indicated by Kirdmanee and Mosaleeyanon (2000) 21. Considering the high level of regulation against testing genetically modified plants under natural environmental conditions, the photoautotrophic micropropagation method could provide the advantage of inducing phenotype expression under conditions similar to those of a greenhouse, but in a highly contained situation.
