Abstract

Electric field conditions have been regulated for optimum growth of corn as determined from field delay experiments on both corn and bean plants in a reversed electrostatic field, a conventional electrostatic field,and an electrokinetic (60 cps) field. These experiments have established the critical dynamic potential gradient (field strength necessary to induce physical leaf damage)at about 100 kv/m for extended electrification ( >10 hr) or corn and bean plants.Field delay or field intensity-time duration experiments on corn and bean plants allow a possible relationship between plant growth and storm conditions in the natural environment to be established.

Zusammenfassung

Es wurden elektrische Feldbedingungen für optimales Wachstum von Mais eingestellt, die in Feldverzögerungs-Experimenten mit Mais- und Bohnenpflanzen im umgekehrten elektrostatischen Feld, konventionellen elektrostatischen und elektrokinetischen (60 cps) Feld ausgearbeitet worden waren. Uber diese Experimente wurde der kritische dynamische Potentialgradient für Mais- und Bohnenpflanzen erarbeitet, das ist die Feldstärke, die erforderlich ist,um wirklichen Blattschaden zu erzeugen. Er liegt bei ausgedehnter Elektrifizierung ( >10 hr)bei ungefähr 100 kv/m. Feldverzögerungs- oder Feldintensitäts-Dauerexperimente mit Mais- und Bohnenpflanzen gestatten die Ausarbeitung der möglichen Beziehungen zwischen Pflanzenwachstum und Gewitter in der natürlichen Umwelt.

Resume

On a établi des conditions de champ électriques provoquant une croissance optimum du maïs. Pour ce faire, on s'est basé sur des recherches portant sur les effets de retardement dû au champ tant sur le maïs que sur des pois dans un champ êlectrostatique renversé, conventionnel ou électro-cinétique (60 imp/sec). Ces essais ont permis d'établir un gradient potentiel dynamique critique (champ absolument indispensable pour occasionner des dégâts physiques aux feuilles)et cela pour les deux dites plantes. Ce gradient est voisin de 100 kv/m pour une mise sous tension de longue durée (plus de 10 heures). Des essais de durée de l'intensité du champ ou de son effet retardateur, essais effectués sur du maïs et sur des pois,permettent détablir la relation probable qui existe entre la croissance des plantes et les conditions orageuses naturelles.
