The germplasm of plants may be stored as a seed collection in gene banks or cryobanks. Gene bank conservation of plant seeds (at about – 20 °C and 7% residual humidity of seeds) is preferable to field conservation since climate change can affect the viability of on-farm conservation of landraces by changing the environmental conditions so much that growing a crop in its centre of diversity becomes non-viable and leading to its „extinction‟ in particular regions or agroecosystems. However, both germination rate and biochemical indeces such as enzyme activities of conserved seeds are altering with time. Hence, germination tests and biochemical analyses from time to time of plant seeds stored
