Reason why seeds will not germinate

Commercial processing of seeds is designed to ensure maximal germination, not to stop them germinating.The simple fact is that not all seeds are viable, just as not all pregnacies result in children.For various reasons seeds can fail. Sometimes that is because of genetic flaws within the seeds. Sometimes the seeds get infected with diseases or mites that eat them before they germinate.

Mostly seeds fail simply because theye weren’t treated right. Sometimes the seeds are too old and have died. Sometimes they are buried too deep, or have been watered too much, or not watered enough, or let get to hot, or too cold or a million other environmental factors that prevent germination.

• Conditions needed for germination

• The opportunity to germinate may come if the soil is disturbed in some way; for example, if a fire sweeps across the land or if humans or grazing animals destroy the growing vegetation.

• The conditions needed for seeds to germinate vary from species to species. In general we can say that all seeds need water and warmth to germinate.

• Temperature

• In general, most seeds will germinate at temperatures between 10°C and 35°C. Some seeds, however, need a period of cold before they will germinate. For example, cherry seeds will germinate better if they are kept humid at 5°C for 16 weeks. If these seeds are kept at 25°C they will not germinate. This period of cold temperature “tells” the seeds that winter has passed by.
