Effect of Light Irradiation on Plant Growth and Nutritional Content of Vegetables Intended for Closed Plant Factory

Solar irradiation affects photosynthesis and the composition of vegetative tissue.Here, the effects of UV-A irradiation on growth, and amino acid and vitamin content were investigated in %UDVVLFDUDSD. % UDSD seeds were planted in soil in pots saturated with nutrient solution under four light irradiation regimes: natural light plus red light, blue light, visible light or UV-A light. Experiments were conducted in an air-conditioned room with constant irradiation. Growth rate and dry weight, and nitrate ion (NO

) , amino acid, ascorbic acid and chlorophyll concentrations were measured in the dried leaves. In the present research, we examine the effects of UV-A irradiation and the timing of its application on plant growth and the quality of postharvest vegetables. The results show that the stress of UV-A irradiation slowed foliage growth and decreased rate of photosynthesis.
