Which of the following is not a method of ex situ conservation

Germplasm Conservation The uses of germplasm conservation are varied and include plant breeding for agriculture, horticulture, and forestry, as well as restoration of damaged habitats. From: Encyclopedia of Applied Plant Sciences (Second Edition), 2017 Related terms: • Cultivar • Genetic Divergence • Gene Bank • Mango • Plant Breeding • Germplasm • Genetic Resource C.A. Offord, in Encyclopedia of Applied Plant Sciences (Second Edition), 2017 Abstract Germplasm conservation underpins global efforts to ensure future food security by capturing natural and existing crop diversity, and developing new crops for agriculture. It is also essential for forestry and horticulture and, increasingly, for the restoration of degraded lands and to maintain ecosystem services in the landscape. Germplasm conservation may be ex situ, in seedbanks or other genetic repositories, or in situ, on farms or in natural parks and reserves. Bioinformatics, including high-throughput phenotyping and DNA technology, such as next-generation sequencing, is becoming increasingly important in understanding and managing germplasm collections. Efforts to conserve germplasm at local, national, and international levels are in place and aimed at equitable sharing of material and relevant information in the spirit of the Convention on Biological Diversity. Germplasm conservation is the most successful method to conserve the genetic traits of endangered and commercially valuable species. Germplasm is a live informat...

The method of preservation of components of biological diversity outside their natural habitats is called as ex situ conservation. Cryopreservation is the method of preservation where the species are preserved at very low temperature to preserve structurally intact living cells and tissues. The agroforestry, sanctuary, and biosphere reserve are the methods of in situ conservation.

• Biodiversity conservation can be done in two modes i.e . In-Situ andEx-Situ. • The mode of conservation whichincludes protective maintenance of threatened species outsidethe areas where they naturally occur is called as Ex-Situ Conservation. • Examples: Zoological parks and Botanical gardens, in-vitro fertilisation, tissue culture propagation and cryopreservation of gametes • In-Situ Conservation:The conservation methodto protect the entire ecosystem in which the species are protected in their natural habitat. • Examples:National parks, SanctuariesBiosphere reserves, Reserved forests,Protected forests In-vitro fertilisation: • In vitro fertilisation is a process of fertilisation where an egg is combined with sperm outside the female body, in vitro. • It is a method of ex-situ conservation. Tissue culture propagation: • Somatic tissue can be storedin vitrofor short periods of time. • This is done in a light and temperature-controlled environment. • It is an ex-situ conservation method. Biosphere reserves: • Biosphere reserves cover very large areas, often more than 5000km 2. • They are used to protect species for a long time. • It includes protecting threatened species in their natural habitat . • It is a method of in-situ conservation. Cryopreservation of gametes: • The storage of seeds, pollen, tissue, or embryos in liquid nitrogen is called Cryopreservation. • It is a method of ex-situ conservation. • This method can be used for virtually indefinite storage of material...
