Abstract

Growth rate studies were conducted on barley plantings exposed to vertical electrical fields of 50–400 kV/m and also to plantings exposed to the gaseous by-products dispersed from such high field exposures. In general, direct exposure to fields below about 200 kV/m produced enhanced growth while higher fields inhibited growth. For all fields up to 750 kV/m gaseous by-products carried to an adjacent planting resulted in increased initial growth, this gain eventually being lost as total growth dropped back to normal after about 150 hours.

Zusammenfassung

Studien der Wachstumsrate wurden ausgeführt mit Gerstensetzlingen, die vertikalen elektrischen Feldern von 50–400 kV/m und den gasförmigen Nebenprodukten derartig hoher elektrischer Feldbelastung ausgesetzt waren. Die direkte Feldbelastung unter 200 kV/m bewirkte im allgemeinen ein verstärktes Wachstum während bei höheren Feldstärken das Wachstum gehemmt war. In allen Feldern bis 750 kV/m führten die gasförmigen Nebenprodukte zu einem anfänglich gesteigerten Wachstum. Dieser Gewinn ging später verloren, indem das Gesamtwachstum nach 150 Stunden auf Normalwerte zurückfiel.

Resume

On a étudié le taux de croissance de jeunes plantes d'orge exposées à des champs électriques verticaux de 50 à 400 kV/m, ainsi que de germes exposés aux émanations gazeuses provenant de tels champs électriques à haute intensité. En général, l'exposition directe à des champs de moins de 200 kV/m à peu près provoque une augmentation de la vitesse de croissance, alors que des champs supérieurs ont un effet inhibiteur sur cette même croissance. Dans tous les champs électriques jusqu'à 750 kV/m, les produits gazeux accessoires ont eu pour conséquence au début, une croissance supérieure. Pourtant, ce gain s'est perdu par la suite, du fait que la croissance totale est retombée à des valeurs normales après 150 heures.
