Seed and Germination
Ripe seeds are extremely resistant to both heat and cold. Some can survive the temperature of liquid hydrogen and some can bear, for a period that of boiling water. Moreover their respiration rate is so low that many can remain viable for many months in the absence of free oxygen. By contrast the vegetative parts of plants that are used for propagation – tubers, bulbs, etc. – are much more sensitive to heat and cold, and are dependent for survival upon a supply of free oxygen. Potato tubers, for example, are killed by a few degrees of frost, by heating to comparatively low temperatures, and, in perhaps two of three days, by submersion in oxygen-free water or in waterlogged soil.
It isa familiar fact that seeds of different species germinate at different rates.
Beets and carrots germinate slowly, cereals very fast. In many cases germination can be speeded up by wetting the seed before sowing. The length of time that seed will remain viable varies greatly from one species to another. Onion seed deteriorates rapidly, even under good conditions of storage. The seeds of many common weeds survive in the soil for long periods in some cases for several decades.
