The primary reasons for failed germination are:

Seeds get eaten

– mice, voles, birds, and wireworms all eat seeds. Check to see that the seed is still in the soil. Seeds rot – planted too deeply, over-watered, or in cold weather, our untreated seeds may simply rot.

(1) Imbibition (2) Respiration (3) Effect of Light on Seed Germination(4) Mobilization of Reserves during Seed Germination and Role of Growth Regulators

gram, pea, groundnut

are some common examples of hypogeal germination.

Does heat speed up germination?

Tips for Warming Soil to Speed Up Seed Germination

Seeds need both moisture and warmth to germinate.

Warm up the soil before sowing your seeds

. … Keep in mind that high temperatures will kill seeds or dry out seedlings, so stay in the desired temperature range. More is not more.

What are two types of germination?

  • Epigeal Germination: In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil. …
  • Hypogeal Germination: In this type of germination, the epicotyl elongates and the cotyledons remain below the soil.

Is too little heat bad for seed germination?

Most seeds will germinate over quite a wide range of soil temperatures but the speed of germination will vary. Too cold and they'll be very slow to sprout and

too hot will also reduce the speed of germination

. Far too cold or hot and they'll just fail.
