Z. Naturforsch. 46c, 542-548 (1991); received February 13, 1991 Blue-Light Photoreceptor, Chlorophyll Synthesis, Desmarestia aculeata, Green-Light Photo receptor, Nitrate The chlorophyll synthesis in the brown algae Desmarestia aculeata is affected by light quali ty and by the nutrient state in the medium before the illumination. Pulses of 5 min of red, green and blue light together with 200 ...
BACKGROUND Vulnerability to the reduction in natural light associated with fall/winter is generally accepted as the main trigger of seasonal affective disorder (SAD), whereas light therapy is a treatment of choice of the disorder. However, the relationship between exposure to light and mood regulation remains unclear. As compared with green light, blue light was shown to acutely modulate emotio...
There is a seasonal cycle of sexual activity for all species of birds. It is more or less pronounced according to the species, and it is primarily controlled by the external factor of light, the daily duration and intensity of which vary during -the year, the minimum amount of light being present on December 21, while the maximum is reached on June 21 in the northern hemisphere. Rowan54 was the...
This research work involves the dyeing of wool yarns with saffron petals as a source for green color. At first step woolen pile yarns treated with four different mordents, namely: tin chloride, copper sulfate, aluminum sulfate and iron(II) sulfate in acidic condition using acetic, oxalic, citric and lactic acids respectively. In this study the possibility of using saffron petals as a natural dy...
At a concentration of 0.025% (w/v) chitosan-chloride inhibited spore germination of Botrytis cinerea, Penicillium expansum, and Candida saitoana. In contrast, at 0.5% (w/v) glycolchitosan inhibited spore germination of B. cinerea and P. expansum, but not the growth of C. saitoana in vitro or in apple wounds. The combination of C. saitoana with 0.2% glycolchitosan was more effective in controlli...
Persistent holograms are recorded with green light in LiNbO(3) crystals doped with Mn and Fe. The recording sensitivity is 20 times better than that obtained by recording with red light. Partial loss of persistence is caused by using green light for recording.
