The influence of artificial lighting on the state of the fund of photosynthetic pigments of assimilating and generative organs of tomato plants
Abstract
The results of a study of the effect of artificial lighting on the formation of a pigments fund of plastids of tomato plants (Fanto variety) in a production experiment with a 4-variant scheme – natural lighting (control), using a DNAT sodium lamp with a power of 600 W, as well as LEDs of the brands Arlight and Eviyar with a power of 112 and 127 W, respectively. The positive effect of all light sources on the saturation of the pigment fund of plastids has been established with varying degrees of manifestation of the effects in the assimilating and generative organs of plants.
It has been shown that despite the higher saturation of the pigment fund of the assimilating organs against the background of LED lighting, the most pronounced increase in the accumulation of pigments in tomato fruits compared to the control was found when using a DNAT sodium lamp, which indicates a slight slowdown in the process of their maturation when using LEDs.
