Seedkäyrää

Seedkäyrää is a Finnish term that translates to "seed curve" or "seed arc." It refers to the graphical representation of the seed germination rate over time. This curve is a fundamental tool in seed science and agriculture, providing insights into the viability and vigor of a seed lot. The horizontal axis of the seedkäyrää typically represents time, measured in days or hours, while the vertical axis indicates the cumulative percentage of seeds that have germinated.

The shape of the seedkäyrää is characteristic of a particular seed type and its storage conditions. A typical seedkäyrää starts with a lag phase where no germination occurs. This is followed by an exponential phase where the germination rate is highest, and finally, a plateau phase where germination ceases, and the curve reaches its maximum germination percentage. Factors such as temperature, moisture, light, and seed dormancy can significantly influence the shape and duration of each phase.

Analyzing the seedkäyrää allows researchers and farmers to determine optimal sowing times, predict crop establishment, and assess seed quality. A steep, rapid curve indicates high germination vigor, while a slow, drawn-out curve might suggest dormancy issues or reduced viability. Understanding the seedkäyrää is crucial for ensuring successful crop production and efficient seed management.
