Effects of seed traits on weed seedbank dynamics in response to seed depth and soil structure
2008
International audience; Weed seedling establishment in fields strongly depends of soil tillage because it determines both seed depth and soil structure. Species can differ in their ability to develop after germination a shoot able to grow towards the soil surface. The length of the pre-emergent shoot growth is limited and seed size could be a key functional trait related to the maximum shoot growth. Besides, during pre-emergent growth, a proportion of seedlings can remain blocked under obstacles into the soil. This mortality could be linked to the hypo- or epicotyl morphology. This trait could be correlated to the emergence force exerted at the extremity of the shoot in the soil. The maxima…
