THE article by Dr. C. F. C. Beeson in Nature of October 26, p. 572, is a welcome attempt to sort out the many conflicting references to a subject of much importance and of wide interest. Numerous factors go to the growth of a plant, and I felt many years ago that it was necessary first to find out the chemical and physical effects of moonlight under simple controlled conditions. The research was carried out chiefly under the bright moonlight of South Africa. Moonlight is partially polarized… Expand

Lunisolar tidal force and the growth of plant roots, and some other of its effects on plant movements.
TLDR
Experimental observations indicate a putative lunar-based relationship with the rate of elongation of roots of Arabidopsis thaliana maintained in constant light, and the evidence suggests that there may be continuous modulation of root elongation growth by the lunisolar tidal force. Expand
Effects of some internal and external conditions on seed germination
TLDR
The present chapter and the following one will deal with the physiology of seed germination as such, i.e. seeds which are fully able to germinate as soon as given the conditions directly necessary for activity and which may be called quiescent seeds. Expand
Plants and the Moon - Traditions and Phenomena
When the annual reunion of the Swiss Natural Sciences Society was held in Lucerne in 1834, the German geologist Jean de Charpentier—a defender of the modern theory of glaciations— was able to attendExpand
Moon and Cosmos: Plant Growth and Plant Bioelectricity
Many of the growth movements of plants (diurnal leaf movements, and perhaps stem dilatation cycles) initiate action potentials which are propagated within the plant body. Action potentials are thenExpand
Full moonlight-induced circadian clock entrainment in Coffea arabica
TLDR
A massive transcriptional modification in Coffea arabica genes under full moonlight conditions, particularly at full moon zenith and 3 h later is reported, confirming this huge impact of weak light on the transcription of circadian clock genes in controlled conditions mimicking full moonlights.

Degradation of starch by polarised light
Abstract Aqueous suspensions of either original corn starch (30%, w/w), or starch heated for 2 h at 120°C in water, were illuminated by linearly polarised visible (>500  nm) light for 5–25 h.Expand
What Has Been Thought and Taught on the Lunar Influence on Plants in Agriculture? Perspective from Physics and Biology
TLDR
It is found that there is no reliable, science-based evidence for any relationship between lunar phases and plant physiology in any plant–science related textbooks or peer-reviewed journal articles justifying agricultural practices conditioned by the Moon. Expand
Polarized‐Light‐Stimulated Enzymatic Hydrolysis of Xylan
The 1‐ to 2‐h illumination of xylanase with visible polarized light (PL) prior to the action of that enzyme upon beechwood xylan significantly increased its activity. The activity only negligiblyExpand
Nonconventional methods of modification of starch.
TLDR
This chapter presents the nonconventional methods for the modification of starch and suggests that the effect of irradiation on starch gels is generally monitored by the changes in viscosity, reducing power, and reaction with iodine. Expand
The Polarized Light‐Induced Enzymatic Formation and Degradation of Biopolymers
White, linearly polarized transformed starch amylopectin into amylose. Moreover, it activated α-amylolysis of starch, hydrolysis of xylane with xylanase, hydrolyses of chitin with chitinase, chitosanExpand
