Abstract
A strong negative correlation has been found between the growth rate of young rice seedlings as well as the coefficient of variation affecting it and the P indices of the chemical test of Piccardi. The correlation coefficients exceed 0.9 with a probability of null hypothesis which is extremely low. The biological effects appear to be due to electromagnetic radiations accompanying the solar eruptions, whereas the chemical test appears to be influenced by the subsequent corpuscular emission.
Zusammenfassung
Eine enge Korrelation zwischen der Wachstumsschnellheit von jungen Reispflanzen sowie deren Variationskoeffizient einerseits und dem P-index des chemischen Piccardi Tests anderseits wurde festgestellt. Die Korrelationskoeffizienten übersteigen 0.9 mit einem äusserst geringen Wahrscheinlichkeitsgrad der Nullhypothese. Es wird angenommen, dass die biologischen Effekte durch die elektromagnetischen Strahlungen bei Sonnenausbrüchen hervorgerufen werden, während der chemische Piccardi Test auf Teilchenstrahlung reagiert.
Resume
Le taux de croissance de jeunes plantules de riz, ainsi que le coefficient de variation qui l'affecte, ont été trouves en étroite corrélation négative avec les indices P du test chimique de Piccardi correspondant à la période de croissance. Les coefficients de corrélation dépassent 0.9 avec une probabilité d'hypothèse nulle tout à fait négligeable. Les variations biologiques seraient l'effet des radiations électromagnétiques accompagnant les éruptions solaires, tandis que les émissions corpusculaires de même origine influenceraient le test chimique.
