Several ways exist of maintaining the genetic resources of crops. The cheapest and most convenient way is by storing seeds. However, not all crops can be preserved by storing their seeds, because they are either vegetatively propagated and/or do not produce seeds, or the period of their seed viab...

Hermetic cold storage without previous drying (wet–cold storage) was experimented for the preservation of yam pollen grains. Pollens collected from white yam D. rotundata and a wild relative, D. praehensilis, were stored at -80, -20, 5, and 150C in sealed packs for 2 years. Pollen samples were dr...
