Factors influencing the germination of seeds of the potato

  • Published:
American Potato Journal Aims and scope Submit manuscript

Summary

  1. 1.

    The percentage and velocity of germination of potato seeds was more satisfactory when planted 1/8-inch deep than when planted at a greater depth.

  2. 2.

    No significant differences were obtained between covering the seeds with soil, or with 50 per cent soil and 50 per cent sand, or with sand.

  3. 3.

    High temperatures reduced the percentage and velocity of germination.

  4. 4.

    Alternating the temperature between 20° and 30° was more satisfactory than a constant temperature of 25°.

  5. 5.

    A higher velocity of germination was obtained when the seeds and seed-ball debris were allowed to ferment before washing and drying.

  6. 6.

    Soaking the seed in an aqueous solution of potassium nitrate did not affect the percentage or the rate of germination.
