Populations of threatened plants are declining rapidly in natural habitats due to various anthropogenic activities. Reinforcement of the dwindling populations through reintroduction is a promising aspect for conservation of threatened plants. However, due to lack of standardized propagation methods of such plants, mass production of planting materials has become a challenge, thereby constraining the replenishment process. Identification of factors constraining the seed germination of threatened plants and addressing it effectively, are among the most cost-effective strategies for large-scale multiplication and subsequent conservation of the threatened species. Similarly, conventional low-cost vegetative propagation techniques such as grafting, air layering, and regenerating plantlets from ischolar_main-suckers, apical meristems, and stem cuttings often prove more successful for multiplication than relatively costly micropropagation techniques. In this article, we present a few case studies on low-cost mass propagation techniques of threatened plant species of India through seed, stem/apical shoot cutting and airlayering, that helped in the restoration of the species.

Abstract


Populations of threatened plants are declining rapidly in natural habitats due to various anthropogenic activities. Reinforcement of the dwindling populations through reintroduction is a promising aspect for conservation of threatened plants. However, due to lack of standardized propagation methods of such plants, mass production of planting materials has become a challenge, thereby constraining the replenishment process. Identification of factors constraining the seed germination of threatened plants and addressing it effectively, are among the most cost-effective strategies for large-scale multiplication and subsequent conservation of the threatened species. Similarly, conventional low-cost vegetative propagation techniques such as grafting, air layering, and regenerating plantlets from ischolar_main-suckers, apical meristems, and stem cuttings often prove more successful for multiplication than relatively costly micropropagation techniques. In this article, we present a few case studies on low-cost mass propagation techniques of threatened plant species of India through seed, stem/apical shoot cutting and airlayering, that helped in the restoration of the species.
