Title : Monochromatic LEDs lighting affects redox homeostasis and morphological traits in lentil seedlings

Abstract:

It is known that the light is an environmental factor with a key role in plant growth and development processes. In the last years, in addition to the different and conventional lighting modes in greenhouses, very attention towards the use of light-emitting diodes (LEDs) has been paid. This technology includes the use of spectral light with the possibility to choose the quality and quantity of lighting in plant. The use of LED allows to evaluate as the single monochromatic light can affect the redox state in plant cell and some morphological parameters. Particularly, the monitoring of parameters involved in redox homeostasis such as reactive oxygen species, enzymatic and not-enzymatic antioxidant systems, and thiol-disulfide status of proteins, are useful to better comprehend the responses of the plant to the single monochromatic light.

Seeds of Lens culinaris L. (lentil) were germinated and grown in darkness (control) or under continuous different LEDs at different light intensities. The analyses were carried out at the early growth stages of the seedlings. The study highlights how quality and quantity of the LEDs light differently affect the biochemical and morphological parameters analysed. Particularly, red monochromatic has a positive effect on biometric parameters such as length and fresh weight whereas blue monochromatic light positively influences enzymatic and non-enzymatic components such as ascorbic acid and phenols. Future studies are needed to conduct an in-depth analysis how the light conditions can strengthen the antioxidant machinery and induce anatomical modifications useful to improve crop productivity and stress resilience through a sustainable approach.

Biography:

Dr. Costantino Paciolla studied Biology at the Bari University Aldo Moro, Italia and graduated as MS in 1987. After two years fellowship of Accademia Nazionale dei Lincei in Agricultural Genetics Studies, he obtained the position of permanent researcher and then of Associate Professor in Plant Physiology at the same institution. His research concerns the study of the redox homeostasis in plant cell under biotic and abiotic stress and the influence of light on antioxidant activity and photomorphogenic growth in plants of food interest. He has published more than 70 research articles in journals with impact factors present in Scopus database.
