    ABSTRACT: Carrot seeds which had been imbibed or germinated and were then sown in a gel extruded through standard coulters emerged five days earlier than dry seeds sown with a conventional drill and gave higher yields after 64 days although not after 77 days. There was no difference in mean time to emergence or in final plant stand between lettuces grown from dry seeds and those from seeds imbibed for 24 h and sown in a gel, but the duration of the emergence period of the latter was halved in one of the two experiments. Celery seeds, the light requirements of which had been satisfied during germination in optimum conditions in the laboratory before they were sown in the field in a gel, gave a 60% plant stand as compared with a stand of 2% from dry seeds.

    ABSTRACT: Abstract— Les résultats des expériences réalisées sous différentes conditions d'éclairement et de température ont permis de définer deux processus de germination probablement indépen-dants: 1°/un processus thermosensible: à l'obscurité la germination ne se produit qu'en alternance de température. L'éfficacité de ces alternances est fonction de l'éart qui existe entre les deux températures et de la valeur de ces deux températures. L'influence des alternances de températures peut être exaItée par un certain nombre de substances: nitrates, nitrites, hydroxylamine et thiourée 2°/un processus photosensible: la lumière rouge clair (630–680 mµ) stimule le germination, par contre la lumière rouge sombre (700–730 mµ) élimine la stimulation due à la lumière rouge clair. L'acide gibbéréllique sensibilise les graines à la lumière rouge clair.
