The aim of this study was to investigate the effects of different LED lights on the growth of cauliflower microgreens and to determine which combination of LED light best increases tolerance to salt stress and promotes the growth and accumulation of secondary antioxidants in the presence of salt stress in vitro. Plants were grown in a growth chamber under different LED light treatments (red light, blue light, a combination of red and blue light, and cool white light) and in MS media with different NaCl concentrations (0, 50, and 100 mM). The effects of the different light qualities and salt stress conditions on growth, content of photosynthetic pigment, flavonoids, phenol, proline, and antioxidant enzyme activity were measured. The best treatments for microgreen development, according to the data, were those that combined red and blue light. In addition to increasing stress tolerance and enabling plant growth at a lower salt concentration (50 mM NaCl), the combination of blue and red light also enhanced the synthesis and accumulation of secondary metabolites and the antioxidant potential of microgreens grown in vitro, which may have nutritional and pharmaceutical value.

One of the goals in eggplant breeding (Solanum melongena L.) is higher yield. This study included 20 different genotypes that are part of the collection of the Institute for Vegetable Crops Smederevska Palanka. Sixteen genotypes originated from Serbia, two originated from the Netherlands, one originated from Italy, and one originated from Israel. The experiment was conducted at Vranovo (44°36′6.35″ N, 20°59′55.47″ E, altitude 87 m) using a randomized complete block design and three replications. The yield parameters (earliness, plant height/centimeter, number of fruits per plant, fruit weight/gram, fruit length and width/centimeter, and fruit yield per genotype/kilogram) were examined to study the relationships among traits and their effects on eggplant yield. The number of fruits per plant had a positive and significant correlation with yield (r = 0.685 **). Additionally, the results showed positive correlations between plant height and fruit length (r = 0.812 **), between plant height and fruit weight (r = 0.147), and between fruit width and fruit weight (r = 0.523 *). These characteristics had direct or indirect positive effects on yield, so they can be used as selection criteria to increase the final yield of eggplant. Because there is genetic variability between the tested genotypes, progress in breeding will depend on this variation. Earliness had a negative correlation with yield (r = −0.044) and with all other parameters.
