  • 2 and sometimes 4.

    2. Seeds need water and oxygen to germinate. Oxygen to start respiration so the seedling can break the surface. Too deep, no oxygen.

    4 Some seeds particularly in jungles need light to reach them from the canopy or they won’t germinate. This is not true for seeds not originating in jungles.

  • 2) due to unavailability of air.
    “Seeds sown deeply in soil, fail to germinate because of lack of oxygen. Ploughing aerates the soil and helps in good germination”
