Earthworm collection from agricultural fields: Comparisons of selected expellants in presence/absence of hand-sorting Inra
Pelosi, C.; Bertrand, M.; Capowiez, Y.; Boizard, H.; Roger-Estrade, J..
The role earthworms play in soil fertility is under increasing scientific scrutiny, especially in light of the fact that farmers are seeking to reduce soil tillage. However, there are many discrepancies in earthworm sampling methods. The aim of this study is to compare the efficiency of three chemical expellants (formaldehyde, commercial ‘hot’ mustard and allyl isothiocyanate, abbreviated AITC), with two sampling methods: (i) a simple method that consisted in spreading an expellant solution on the soil and retrieving earthworms that emerged at the soil surface, and (ii) a combined method that consisted in applying a chemical to expel earthworms and then hand-sorting the remaining earthworms from the block of soil. Sampling efficiency was measured in terms...

La crise de croissance de la plantule de mais a basse temperature Inra
Derieux, M.; Bourdu, R.; Duburcq, J.B.; Boizard, H..
La crise de croissance étudiée chez la plantule de maïs par Bourdu et Gregory (1983) en conditions de températures favorables se retrouve, accentuée mais au même stade, en conditions froides. Cette crise semble correspondre à l’établissement des translocations vers les racines. Le poids initial et la texture de la semence ont une influence sur la vitesse de croissance et l’utilisation des réserves.
