The role of low intensity red luminescent radiation in the control of Arabidopsis thaliana morphogenesis and hormonal balance

Lanthanide-Based Luminescent Hybrid Materials

“…Productivity increases up to 100% for plants in greenhouses have been reported after the use of polymer films with these additives. The faster growth and development of plants under such films is known as the Polysvetan effect , − which is thought to be caused by the effect of low-intensity red luminescent radiation on the plant hormonal balance . Examples of europium(III)-containing dopants for polymer films are Y 2 O 2 S/Eu 3+ , − Y 2 O 3 /Eu 3+ , and Eu(phen) 2 (NO 3 ) 3 .…”

“…The faster growth and development of plants under such films is known as the PolysVetan effect, [1097][1098][1099] which is thought to be caused by the effect of low-intensity red luminescent radiation on the plant hormonal balance. 1100 Examples of europium(III)containing dopants for polymer films are Y 2 O 2 S/Eu 3+ , [1101][1102][1103] Y 2 O 3 /Eu 3+ , 1102 and Eu(phen) 2 (NO 3 ) 3 . 1102 Yang and coworkers describe luminescent films for agricultural applications prepared by doping [Pr(sal) 3 (phen)] and [Eu(sal) 3 -(phen)], where sal ) salicylate and phen ) 1,10-phenanthroline, in different molar ratios in linear low-density polyethylene (LLDPE).…”

“…Likewise, it is known that, under conditions of low illumination, red light effectively intensifies photosynthesis [29], which could also be the case in our work. Also, the contribution of red light emitted by phosphors can stimulate a change in the content of phytohormones [30]. IR absorption and luminescence in the red region can change the ratio of red and far red light and thus activate the phytochrome system, which, in turn, can intensify photosynthesis, increase stress resistance and accelerate plant growth [31,32].…”

Influence of low-intensity laser radiation on the dynamics of some phytohormone content in the callus tissues of wheat Triticum aestivum L.

“…In addition to these compounds, of special interest is indoleacetic acid. This phytohormone is one of the main plant growth and development regulators, and is shown to be characterized by a rapid change in content (a decrease, as a rule) in response to the influence of various stressors [17].…”
