Lunar Rhythmicities in the Biology of Trees, Especially in the Germination of European Spruce (Picea abies Karst.): A New Statistical Analysis of Previously Published Data
Abstract
Interest in the question of moon-related fluctuations in tree biology and physiology has been revived by recent
experimental research, which could confirm the existence of real phenomena. In this context, previously
published extensive data from germination tests on European Spruce using established standard devices, which
appeared at the time to give negative results, has been analysed with the help of modern statistical tools. Slight
but statistically significant lunar rhythmicities were revealed by this new analysis. One of these fluctuations is
found in the germination rate from sowings shortly before Full Moon, compared to those shortly before New
Moon.
