Growth and photosynthesis of Chinese cabbage plants grown under light-emitting diode-based light source. However, since we found that the responses of the photosynthetic apparatus of tomato plants to a particular light regime were cultivar-dependent and there was a weak correlation between the growth and photosynthetic parameters tested in this work, special attention should be paid in future research.Īvercheva O, Berkovich YA, Erokhin A, Zhigalova T, Pogosyan S, Smolyanina S. Our results can be used to improve the production of tomato plants under artificial light conditions. On the other hand, the mixture of red and blue light with a high proportion of blue light led to an increase in non-photochemical quenching (NPQ). This was demonstrated by the increase in the effective photochemical quantum yield of PSII (Y), photochemical quenching (qP) and electron transport rate (ETR). Our results showed that the best performance of the photosynthetic apparatus was observed under a mixture of red and blue light (R7:B3) or a mixture of red, green and blue light (R3:G2:B5).
In this work, we tested the responses of the tomato photosynthetic apparatus to different light spectral qualities. Chlorophyll a fluorescence measurement has been widely used as a rapid, reliable, and noninvasive tool to study the efficiency of the photosystem II (PSII) and to evaluate plant responses to various environmental factors, including light intensity and quality. However, the influence of the new light sources recently used in horticulture, known as Light Emitting Diodes (LEDs), on this process is not yet fully understood. It is already known that the process of photosynthesis depends on the quality and intensity of light.
