Abstract:   (160 Views)
Microgreens are considered a functional food that can be so useful for increasing the health level of society. This experiment was conducted in factorial format based on a completely randomized design with two factors. The first factor, light spectrum, was investigated at four levels, and the second factor, sulfur nutrition, at two levels (0 and 60 mg/liter). The light treatments included different ratios of red (R) and blue (B) light (R1B2, R1B1, R2B1, and R3B1). The highest leaf length was recorded in the R3B1 treatment without sulfur feeding, which was significantly higher than all other treatments used. The length of the stem in the combined treatment of R3B1 with sulfur feeding showed the highest figure. The highest amount of total chlorophyll was obtained in R1B2 treatment with sulfur feeding, although their difference with R3B1 treatment with sulfur feeding and R2B1 without sulfur feeding was not statistically significant. In carotenoid pigment, the highest amount was seen in R2B1 treatment without sulfur, which did not show a significant difference with R1B2 without sulfur feeding. The total antioxidant activity showed the highest value in R3B1 treatment without sulfur, and its difference was not significant between R1B1 treatment without sulfur and R1B1 with sulfur feeding. The maximum calculated phenol was recorded in R2B1 treatment without sulfur, which was not significantly different from R1B2 treatment without sulfur and R3B1 with sulfur feeding. The most flavonoids were obtained in the R1B2 treatment without sulfur feeding, which was significantly more than all other treatments. Since the high proportion of red light in conditions without sulfur nutrition caused proper morphological growth and also increased the antioxidant capacity of the plant, therefore the mentioned treatment is recommended for the production of broccoli microgreens under artificial light.
